Millercarbon's Mega Moab Mod Meander
One of the all time great automotive engineers, Norbert Singer, was a key player in every one of the 16 Porsche LeMans victories from 1970 to 1998. His dominance was such that at one point Porsche had won LeMans more than all other marques combined. This was all accomplished by building on the already solid foundation of Porsche production models. The air cooled flat 12 in the 917 was really two flat sixes combined to make 12. This car so dominated motorsport the rules had to be changed to stop it!
So Norbert Singer modified Porsche production technology to extract the absolute most for racing. His legacy is today’s Singer Vehicle Design https://singervehicledesign.com Norbert doesn’t make for a very good car name so they called it Singer. What is a Singer? It is a modified Porsche. It is in essence a hot rod. What Norbert Singer did was make the most hot rod racing Porsche. What Singer does is take that to the next level, capturing every aspect of Porsche right down to excellence of design and aesthetics.
I am not anywhere near the level of Singer. But that is the spirit of what we are doing: taking an already world-class design and hot-rodding it to be even better. Well, better for me anyway- or so we hope!
The early modders started with substituting off the shelf parts to get more power or less weight. That is pretty much all we are doing here. Would be cool if some day people are doing this with a lot more sophisticated approach. Maybe they will. Maybe even I will. For now though we have the current crossover project.
My approach is pretty simple: better parts sound better.
This lesson was learned back in the late 90’s with Linaeum Model 10 speakers. The designer had a new tweeter and told me how to modify the crossover for it. Simple mod, one cap, one resistor. Bought the parts from Radio Shack, put it together, sounded like crap. Absolute horrid crap! Called him up, he said those parts are crap. Said Musicap, Vishay. But they measure the same? Just do it. I did. It worked. Even though they measure exactly the same, the sound difference is off the charts.
Even though they measure exactly the same. There is a lesson here. For those willing to learn.
So this is the essence of it: Eric Alexander has made a speaker the equivalent of a Porsche 911. Even better: an affordable Porsche 911! But after a while with my 911, after learning what makes it drive and feel the way it does, it was only natural to change the shocks and torsion bar and other items to bring out even more of what I like so much about the 911.
That is what we are doing here. Hot-rodding a speaker. Thank you Rick for the metaphor!
The parts are on order. Next week the fun begins!

Let’s see if I got this pic posting thing right. Here is the crossover for the upper section of my double impacts. When the boxes are complete (parts on order) the wires coming from the drivers and out the rear of the speaker will be into one neat sheathed cable with each wire terminated with a male GR Research tube connector and the xover components will be soldered to wire connected to female GR conns. mounted to the boxes rather than the copper post units you see now, the components will be fastened with zip ties. When finished they will be painted black along with the covers I made for the boxes. The boxes are dove tailed drawer boxes. https://postimg.cc/y3cvzHy2/7333bf4f |
While I don't own a Porsche I do own an Audi TT but that's not the point. The guy that rebuilds the Powerdyne BD-11 supercharger for my S-10 ZR2 4.3l engine is a huge Porsche enthusiast. Check him out here: https://928motorsports.com/ |
Woke up this morning around 5AM couldn't go back to sleep so started working on the crossover. Incredible how much time it takes to put this thing together with all the tweaks and short leads and tight space. Anyway, just finished soldering it all together. Everything still needs to be glued down but this is pretty much what it will look like. https://systems.audiogon.com/systems/8367 One shot shows the parts just laid out to see if they will fit. Most of them are covered over with fO.q tape and the whole thing is mounted on a Tetrault Quantum of Solace, and will be laminated to a BDR Shelf on Townshend Pods. This all goes on a brace behind the lower woofer. Getting it glued down and in there should take up the rest of the day. Really want to hear this tonight!😍 |
I read in Sound and Vision magazine the half-million dollar Rolls Royce had a sound system which has software giving access to every pop song ever recorded. It excludes classical music and opera because according to some market research too few people who buy a Rolls Royce prefer that kind of music, something few people would expect. That taught me the lesson; entering the ranks of the super-rich is not a gateway to the higher and more human forms of culture. |
Sure. PM coming. But I don’t really "do" crossovers. Barely understand the subject. All I do is swap out parts - caps, resistors, inductors - for higher quality parts of the same value. Done a fair amount of this over the years and with speakers, amps, and other stuff, always with good results. Do it right and you don’t really change the fundamental character of the component much at all- it just becomes a whole lot more clean and liquid, with greater detail and a greater sense of ease. Caps are kind of like tubes or cartridges. The better ones are just plain better, but among the better ones you can choose smoother or more analytical. No matter what you choose even the more analytical of the better caps will seem liquid and make even the smoothest cheap cap sound grainy by comparison. |
@millercarbon - I would like to discuss with you, if you are willing, crossovers I’m considering for my Apogee Duetta II Signature Series full range ribbon speakers, but I’m on the fence regarding doing it at all (don’t want to lose the “Apogee” sound I’m so addicted to) and, if I do, if I should go with the caps recommended by Music Technology/ Graz in Australia or maybe consider going a different way. The speakers are being sent to Bill Thalmann @ Music Technology for full restoration anyway. I don’t want to potentially (partially) squander the ~$1,200 I’ll be spending for freight (AR to VA). Are you able to private message me? If not, we can take it offline via email if you prefer. Thanks in advance. |
@ricevs - Air core coils will sound best if you have the signal enter the inside of the foil and exit the outsideFunny, I wired mine signal in on the outside, the core towards ground, I posted the photos in my system page, and that aspect is clearly seen also. I was told the opposite??? I almost had to run the lowest value inductor that way you said, as I had not left long enough leads, but I wound (Andrew Lenehan actually hand wound them, and he's better at it really) a new pair the way they are now. I do know of an Australian speaker manufacturer who bypasses the spade terminals on the basket by drilling off the rivet that holds the mounting plate on, but it’s how he joins the ribbon internal wire that makes it work so damned well. He’s using a special silicone for vibration isolation on the join. I did the same on my larger speakers using Jack Bybees bullets, directly wired in. Thank you, good info mate. Can you imagine the time to do a Tekton array of tweeters eliminating the posts? It took me hours just to silicone mount my bybees to the basket and connecting the tinsel leads on just four drivers - Urrggggh! And he replaced the aluminum baffle on the tweeter with a polished copper baffle, which gave it a significant increase (I had to edit out my Aussie slang, I forget sometimes I can be hard to understand) , well in performance and cost (copper plate and machining aren’t cheap). @millercarbon - I sure hope you read that? Now you have conflicting information, something else for you to investigate. |
rixthetrick OK, My Supercharged car was a first generation 1988. It was not available in the states without T-Tops, although there were a few people who did add the equipment on their own to the non-blown car. I lost to one at the Dog Wood Gran Prix. Unfortunately, most people did not realize that the engine blocks were different, with the S/C engine block. etc. being much more robust, from a spec series race engine. My Turbo was a second generation 1993. You are correct, it was available with or without T-Tops. I owned both cars for a few years The Turbo is the one I used at the Porsche Club events, although the few series championshipd I won weer with the S/C car. A former Porsche National champion father and son had a turbo, and showed me a a few tricks for my car, but never quite enough to beat them. I used B&W (box) car speakers in the former car, with a Soundstream amp. I really like B&W's, having owned at least one set since my early 1970's DM4, which was interestingly a DM2 changed from a ported to a transmission line cabinet. Both used the Celestion upper mid/tweet and the Coles super tweeter that KEF used in their speaker, as did the famous Rogers min-monitors. B&W's first speaker was this KEF that was bought to improve the crossover to create their first speaker, the Domestic Monitor. This B&W, and the KEF from which it was derived, used the squashed 6 x 9 looking KEF woofer that was used to make the cabinet narrower, in order to lower Britain's VAT tax on cabinet width. B&W then came out with narrow stand mount models (DM 2/II, DM7, DM14, DM16, plus the powered DM14 called the Active One. Both designs were originally created to lower this VAT tax. (Added that to make the topic home audio related.) teh |
Air core coils will sound best if you have the signal enter the inside of the foil and exit the outside.....either towards the driver or towards ground. The xover should never be inside the vibrating box. Run the wires out the back and have the xover mounted on damped raised platform.....much easier to upgrade xover with time, as well. The wires to the woofers should be soldered directly to the voice coil wires.......do not go through the binding posts or tabs that are mounted on the driver. Just solder your wire directly to the voice coil wire where it meats its tab. Of course, you do not want distorting binding posts or spades, etc on your speaker wires. You want to hardwire your xover to your speaker wires (the wires from your amp).......or you can use my binding post bypass system for easy connect and disconnect. Less is more. If you have midranges in your speakers.....then hardwire the speaker wire to their voice coil wires, as well.....same with full range drivers....way better sound. Felting around all the tweeters (and midranges) will give a more focused and pure sound. The felt should run right up to the edge of the dome....covering the entire tweeter. All of the speakers I have made or modded all had the above done....always with superior sound. |
Sorry, wasn't even thinking of that angle. Was more like that is how expensive just the caps are. Even with no mortgage I can barely afford Duelund bypass caps! Not that Duelunds would fit in there even if I could afford them! Will have to "get by" with just Alumen Z with the Duelund bypass caps. It will all be good though thanks to my Krissy magic. Heh. ;) |
If you can just do two mortgage payments a month, plus however much you can scrape together at the end of a year of clipping coupons eating beans never going anywhere and never buying anything, then in just 6 or 7 years when the mortgage is paid off you will be absolutely astounded with how easy it is to buy really good capacitors.Been Dave Ramsey-ing it for the last three years mate. Over 20% cash for the deposit (no mortgage insurance), no other debt not even for a vehicle. Started out making somewhere between 6 to 8 times in the principle, but after securing 2.625% rate, I dropped back to double principle payments, and banking the rest for investment. *just ta be cheeky* Oh I already have the capacitors mate, cast Duelund VSF with silver foil bypass caps - the pair cost as much as your entire upgraded crossovers. It would be bragging rites if yours weren't as good, or so damned close in quality. So yeah, you're the lucky buggar with the deal mate. |
stringreen- The truth is that Porsches only become the joy they are at speed. Here in Arizona where everyone is doing 80/90 on the highway, mine starts to make me smile.....the car sticks better, the engine is quieter/smoother, the body becomes more responsive....it becomes a part of me. Around town its much like a Honda/Suberu, etc. https://youtu.be/bXRyy-RBuzc?t=581 |
Rennsport Reunion is the pinnacle of Porsche, at least in the USA. Donahue, Redman, and Bell were telling tales at the Mission when Porsche was the featured marque at Laguna Seca one year. Hurley Haywood's plane barely got him there in time to get to the track, hop in a 914/6 and go from last in the field to win in only I think a 15 or 20 lap race. He won by a foot at the line, most exciting race ever and I was watching from the hill above Andretti Hairpin where between the view and the big screens you could see almost the entire circuit. To top it off this was the last race of the weekend- and Porsche won! After passing the whole field! Thrilling! Haven't heard them myself but Double Impacts are his best selling speakers for a reason. Outstanding reviews. Moabs have the full MTM array. A lot more money but guys who have heard both say well worth the extra. At the same time there are guys who say DI is so good it is their end game speaker. Hard to go wrong with any Tekton, far as I can tell. I'm just east of Seattle in Redmond, and would love to have you over any time. There's so many tweaks that just to give an overview, people ask questions, it can be a good 20-30 minutes just to skim the surface. Seems sometimes like this is all I do, but the truth is years go by doing hardly anything, yet after 30 years it really adds up. This being one of those years where it is adding up a lot faster than average!😂 |

Mr. Miller , thanks for your thread . I love Porsches and I’m considering a pair of Tektons . My Porsche memories are only that of a race fan , but they were some fun times . Number 1 was watching Mark Donahue drive the Sunoco Porsche 917-30 at Laguna Seca . Number 2 is the picture my buddy snapped as I helped Al Holbert push his #14 Lowenbrau 962 into the garage at Riverside. While the 917’s were certainly the Beast of the Era , those 962’s were one of the most consistent race cars ever created . A couple years ago , I got to sit in the Sunoco 917-30 at the Rennsport Reunion at Laguna Seca . Another notable car was the Slantnose rebuilds from Mclaren complete with an F1 engine from either Laudas’ or Prost’ . I’m looking at adding a higher power amp to my single ended SEP system, and obtaining a new pair of Double impacts to replace my Zu Omens . I will certainly spend some time studying your system, as it is light years ahead of mine . I would love to spend time at your house , first to hear your system , and second to learn about your mods . I have certainly learned from this site , and been entertained too . Although growing up in a family that couldn’t afford to have a race car , I was fortunate enough to be exposed by my father to a lifetime of watching races all over California. My fathers school mate raced a Mclaren Can-Am car and owned the famous 198 Cobra that earned its fame later when owned by Dick Smith . So thanks for triggering happy memories and the the Tekton update . Regards , Mike B. |

DHL has delivered the Pods. I have just about decided to stay up however long it takes tonight to get everything fastened and glued down. If I can do that tonight then all I have to do tomorrow is drill and tap BDR, solder, paint, attach the Pods, cut a brace to mount the Pods, cut the Moab braces so this thing will actually fit in there, hook it up, and put the woofer back. That’s all. No problem. Right? |
@flynnrd - as you posted directly under a comment by petg60, (I’m guessing it wasn’t a question for me, but the timing was too good to give up) I just went and played Faithless - Flyin Hi. Okay it’s British rap, and it’s mixed like it’s for audiophiles, and it’s not overly crass or vulgar - and I just love that track on my system. I love the surge, the pull, away from the curbHe’s in a 350Z, but it works for Porsche too :-) Peace brov! @millercarbon - oh the mortgage crack was a good one. I won’t be owning a car until it’s paid off, well so long as my employer keeps buying me new GMC Sierra trucks to drive ;-P |
@danvignau Are you talking about the 1992-1995 turbo MR2? You can get Japanese ones with no t-top at all, my friend had one, and it was a little go kart. A decent body guy could do a cut and shut and you'd be in the business mate! Hardtop MR2,just like it was factory. Come on MC even if it’s just one photo of where you’re at on the crossover?? I wanna see |
sokogear, I am working on another project in tandem with this one. That one in some respects is actually ahead of this one. What I mean, it has passed proof of concept. It has been done. It works. The challenge now is to figure out how to make it cost effective, to sell at a profit and still be good value, and of course to be something people can actually use. Because yes there is a skill level, and there is time. There was a time we had Dynaco and Speakerlab and even today we have some kits people can get a lot for their money if they are willing and able to turn a screwdriver and solder. That is about the level we are talking. That is the way I started, building a Dynaco ST400 in High School. This current project, everything all-in is well over $2k. Probably close to $3k if you count the BDR, Mats, and Pods. Some of this like BDR was already here just sitting around left over but you get the idea. One guy on FB was wanting me to make him one- until I said $2k just in parts! BUT this is more a learning curve thing than an actual problem. The learning curve is what all us who have done mods know very well, that manufacturers always use the cheapest possible parts they can get away with! This means the guy with mere soldering skills can easily do a $5k or even $10k upgrade for $1k worth of parts. We who have done this know this. Problem is hardly anyone else gets it. That is my big motivation for doing this. Already know very well these punch way above their weight even in stock form. With this crossover upgrade, forget about it! Mine are 194 & 195. There are probably by now 200 pair out there. Ten percent market penetration would be huge, but even that would only be 20. So whatever I do will be with the thought in mind there could be a market for this- of a whopping 10-20 customers. Maybe. Michael Spallone does something like this. He figured out a great cap and diode mod for Synergistic Active Shielding MPC. I know, I bought it. Because even though I can DIY he is the man who knows which parts really sound the best. So it would be like that. IF I can get the wiring figured out AND find some really primo wire AND figure out how to deliver something your average motivated screwdriver solderer can handle... but yeah you are right. Any way you slice it, huge amount of work to sell only a small number, just not worth it. That is the challenge all these manufacturers face. Eric's real genius was to figure out a better way of using the same parts to deliver sound at a level no one can touch at that price point. If he made them like mine, even though he would pay maybe $1k for the parts that cost me $2k that would still wind up being $3k for him to profit. At that price people look and see Encore has more drivers. There we are back at the learning curve, they see more and better drivers, crossover components are hidden inside, the average customer just does not and probably will not ever get it. Oh well. We do. Man am I stoked for this weekend!!! |
rushfan71 yes I am sure they will! Ted Denney tells me it is time not power level that soaks and equilibrates dielectrics, so just leave on 24/7 for a week. The Melody blew a tube last week, have been running it on an old spare backup set, might just leave it one and see what happens. At least the first few days anyway, I am off this weekend and next Mon/Tues. Great news! DHL notified me my Townshend Pods are out for delivery! I will have them today! Thank you John Hannant for getting them out so fast! Was thinking the crossovers would have to go in without, then add Pods later. Now it will all be in one fell swoop! Yes!! |
I agree with the concept of what you're saying Chuck, but in reality, most Porsche tinkerers have tuner shops do the upgrades of suspension, roll cages, etc. I don't know of many audio "tuners" out there, heck, there are hardly any repair shops. You doing your own lab work is great, and there is a small number of audiophiles who want to get their hands this dirty. I am surprised there isn't a business out there seeking to upgrade crossovers and drivers in speakers, SS components, etc. If the manufacturers can economically improve the sound, I would think they would want to. Once you start spending more on the product, you have to charge more, and the marketing positioning changes. What you are doing is providing the free labor and paying more for the parts. It's like that car show Wheeler Dealers where they try to make money fixing and improving used cars and selling them at a profit. When they do the summaries at the end of the show, they never appropriately value all the time spent by the mechanic, and even the main guy's time hunting around for various parts. Just like older Porsches typically command more money for originality, I wonder what the market is for homemade upgrades on audio. Now, if they came from a manufacturer, that would be another conversation. |
bullitt5094, Ulf would be a much bigger project. Mine with the new parts will barely fit back in. Pretty sure a little cutting will be called for. My bet would be Eric follows the same pattern and you will find yours behind whichever driver is across from the terminals on the back. I have never seriously considered active because every time it runs into the stone wall of reality. Active means more amps, more power cords, more interconnects, more speaker cables. Every single one of these incredibly important they be done right. It just seems way too easy to give up more than you gain, and that is even before considering money. The parts for this will be almost $2k. The improvement should be staggering. But $2k will not be enough to cover even one good amp if I went active. A good thought experiment. But there is a reason we almost never see anyone doing this at a high level. So don't let imaginary perfection hold you back from making real progress. Even just replacing the resistors in there would no doubt be a big improvement. They are relatively inexpensive too- and might actually fit! ;) |
danvignau, One of my best students, Mark Dennie, had a 79 Targa that was his daily and track car. It remained his daily for more than a decade of autocross and track. I hope to move to TN one day. No worries tespilot, there would already be photo's if this site made it easy to put em up when posting. I have one of the parts laid out all nice and new, and will take another before installing, when they are all wrapped in goo. The only thing about doing it this way, honestly don't know which will be the greater effect, the caps, resistors and inductors or the Quantum of Solace Krissy TDF? Either way it is hard to imagine anything but awesomeness coming out of the Mighty Moabs after this! I look forward to standing corrected, rushfan71, because if you are right astonished it will be. Awesome is overrated and overused anyway. ;) pet60, thanks for reading. That was back when I was putting even more energy into Porsche and being a skilled driver than goes today into audio and being a skilled listener. Both are perishable commodities, something my 911 lets me know real quick every time we go out after too long apart. |
Upgrading the passive crossover components is an excellent idea. It’s always resulted in substantive gains in my experience. But the ultimate upgrade would be an active crossover. That presents a whole new level of complication and expense (like the need for a channel of amplification for each transducer section of each speaker) but results in significant improvement in sound vs passive in my experience. I’ve only played with this on two-way speakers, but I’m sure it will show even more of a difference in 3+ crossover section speakers. What I built for my experiment is a DIY system designed by Nelson Pass. https://www.firstwatt.com/pdf/art_diy%20biamp_6-24_%20crossover.pdf https://diyaudiostore.com/products/diy-biamp-6-24-crossoverYou can add additional crossover points by using multiple boards and interconnecting them. That’s going to be my next experiment. Now, if I am ever brave enough to attempt this on my Ulfs remains to be seen. Not because I would be afraid to do it... I would be afraid my wife would divorce me if I touched those speakers! Great work Millercarbon. Kudos to you for taking this leap. |
millercarbon I had a flexible car that I autocrossed at Porsche meets in Tennessee. The track was a highly banked oval with cones down the straights, and a big drop off into the center X section that made it a figure eight. My Supercharged MR2 actually wore the paint off of the door sills, because the body flexed so much that the door rubbed on it. This was the bane of the SC MR2, because they only came with T-tops. BTW, I did have a fast time of the day in my Turbo MR2. My boy had a 90 advertised hp Subaru GL with the huge Buick Riviera type rear hatch window. It beat a third of the Porsches. That was fun. |
@ rushfan71 - bravo, you used some good quality components. Dyna Mat is a great product. I've never played with No Rez, just read though that it needs to be used carefully? https://forum.polkaudio.com/discussion/159754/installed-no-rez-on-back-and-sides-removed-from-sides Can you put up (even if temporary) a system page with the upgrades you’ve done? I’d like to see the upgraded vs stock as well?? |
Miller, I’ve completely disassembled my entire D.I’s. I had to build the xover for the tweeter array and the 2- 6inch mids outside the box. The mids took 220uf so I used Mundorf Evo in oil. The center tweeter and the surrounding array I used a few Audyne True Copper caps and Path Audio resistors. I’m using the same inductors for now In the woofer section on the bottom, I removed all the insulation and replaced it with no rez. I also used Mundorf MPK caps and Mills resistors for the xover. I intalled Dyna Mat (vibration control sheeting) to the cross braces behind the woofers. I wired the each speaker with Duelund tinned copper wire of the appropriate size If you have any questions or I can figure how to send you some pictures message me. Grannyring was a big help with some questions that I had when I did my D.I’s. I was inspired when I saw that he had done a pair. The results are astonishing compared to stock. |
This little exercise is about just one thing: if you want to avoid an accident, look where you want to go! Don't look at the accident or you will be the accident! This isn't just about avoiding accidents, either. Looking ahead to where you want to go helps you be smooth and fast on the track or auto-cross and safer in everyday driving.I liked that part. |

There is no way you can claim your Tekton speakers are equivalent to a Porsche in status or quality, you either don’t know Porsche cars or you don’t know audio, or both. What you are trying to do is to take a Corolla equivalent speaker and make it a Porsche beater, good luck with that. BTW, I’ll take the Ruf! |
Yes, that is the plan with inductors. Strip of fO.q tape, wrap with Mat, glue and strap em down. Crossover tweaks alone are enough for a big jump in sound quality. Combined with these high end parts you turned me onto it is scary to think how good it will be. Might be. Should be. lol! We will see! After carefully studying your system page Rick I think I have figured out what you are doing wrong. The system will be so much easier and better if you can just figure out how to get rid of the mortgage. |
