Was browsing their website last night about this very issue. Price was listed at $750 MOL for a pair of Xovers and maybe some other tweaks. Sounds reasonable to me...

Have you ask Danny at GR? I have a question. You don't like the way your speakers sound, or have herd the GR XO mod? I just wonder how he balances left to right without having the physical drivers/boxes from your system there.. No two boxes have the exact same drivers.. And no two drivers have the exact same impedance. Maybe I'm being to picky. It's just the way I've seen it done on dozens of pairs of MATCHED speakers.. The two OX never look the same. The coils are hand trimmed and different measurements should be written on the coils and caps to reflect that.. (In case a component fails for repair.) https://www.madisoundspeakerstore.com/xover-design They design, I'm sure if you ship them your parts they will put it together for you. There are a few that will build XOs but normally they want you to buy their STUFF.. Happy hunting though |
Wow that is a BIG XO, for being in a speaker. That thing would be outside the enclosure for me.. No way it would go inside.. That is a going to have vibration issues.. Period.. There would be silicone everywhere. I only see zip ties... That may secure the coils, but no way inside the box. BAD idea with bass in the box and that flexible HUGE XO with upright coils.. Mine would be heaped up with hot glue and silicone OUTSIDE. You can trim the goop to look very nice. The old XO is far better as far a vibration control and size for sure.. Pretty typical of Danny using foam vs sound coat and insulation. The stiffening inside I would wrap with dampening material like dyno mat or something.. They BOING if you don't. I cut the long panel lengths in half with a 3/4 X 2" brace sound coat the inside and black hole the baffle face. Heavy insulation for the bass and wool for the mid/highs. Change the terminal ends to some good ones.. He really like tube connectors.. I like pure red copper I don't care who makes it.. It can be battery lugs for all I care.. Heavy pure copper NO gold plating or any thing else.. I'll bet if you just redo the inside of the box correctly, you won't need to do a darn thing. The 1k peek he was talking about.. ??? It's a peek, easy peasy. Not a valley or suck out.. Wall panels will tame a 1K flame or EQ for god sakes. What state does jerrygarcia reside in? Regards |
If you listen to the video, Danny says "If you don't do the crossover do the box upgrade". You'll notice a difference.. I'd start there and see if fixing the box alone makes a lot of difference.. I bet more so than the XO change.. There is peak he addresses at 1K. Like I said it is a PEAK not a suck out or combing or a crossover issue. It's an EQ issue, and easy to address with a simple GEQ, no need for PEQ or anything fancy. Could probably fix it with simple tone control.. http://www.thebestamp.com/ Maybe these guys.. |
Check out the GR Research forum on Audio Circle for new crossover building service discussion. https://ezeescrossovers.com |
So, GR Research will supply you the parts and schematic, all you have to do is wire it up? If true, you only need to develop soldering skills. Don't you also have Crites and ALK Engineering to choose from? I purchased Crites crossover for my Klipschorns some time ago, diy mods based off that crossover. Jupiter and Audyn caps, Jantzen inductors, Volti mid horns, diy baffle for tweeter, new drivers, all new wiring, etc, etc Point being, more than one way to go for upgrade. I'll just say well worth it for my Klipschorns! All the best attributes and none of the liabilities of stock Klipschorns. |
Just watched 'services' link on GR Research site, see Miflex capacitors being used, those also step up from Sonic cap. They should develop kits for all Klipsch Heritage. Jerrygarcia, many of us diy's could wire this up for you, the problem is responsibility issues and not wanting to make hobby into business. I had to learn modding on my own, diy's willing to offer advice, not services. As someone else suggested go over to Klipsch forums or diy audio forums. Or practice soldering skills, putting together that kit looks to be a novice level mod. I'd predict that kit takes Forte up quite a notch! |
It's well worth the exercise learning to solder. I'm no expert, but I get by. A thin tipped temperature controlled station is well worth purchasing. I prefer a hot tip with a minimum contact time. Just enough to get the solder flowing with a nice silver surface when cooled. The cheap ones on eBay seem ok for occasional soldering. A thin roll of solder with resin is also good. In my own case, there wasn't a schematic as I upgraded the components in my existing crossover. I followed the path on the circuit board and created my own. Good luck and it's not that difficult. |
