New MOFI speaker (Andrew Jones)


Here is some info on the new MOFI/Jones speaker:

 

128x128mofimadness

Not all speakers rated at 87db perform alike. My Atalante 3 monitors are 87 db and  my JBL 4319 are 92db and when I listen to the Atalantes, the volume is turned up only 1 to 1.5db to get the same room filling sound. That's 3 steps on the volume setting if I need to go up 1.5db. Any decent amp will reach levels you wouldn't want to listen to.

As for the bass, the JBLs are -6db @38Hz and the Atalantes are -3db @ 44Hz and it took all of 2 minutes to adjust to the sound of the bass. In fact, it's more tight and defined but not as overpowering. 

All the best,
Nonoise

Audiophile Junkie just posted an interview with Andrew Jones on the SP 8: https://youtu.be/b-OI6FwRAiE

It's the exact same driver as in the SP 10 but trimmed to size.

If any of the sourcepoint 10 owners happen to access the speaker cabinet, please post a crossover parts list and their values. While you're in there, install some .1uf or .01uf bypass caps, and let us know what you hear.

Absolutely! I love tweaking components and will share my findings with you all. However, I need to downsize my systems and will look into new speakers with the Mofi under my radar. I don't have the speakers yet, but a fellow DIYer can help persuade me to make a final decision depending on how accessible the crossovers are.

Do you understand driver design+crossover optimization better than Andrew Jones?

 

Have you ever upgraded coupling caps? If you know, you know.

It's part of the hobby for me. Sorry if that bothers you.

I have read this recently resurrected thread from start to finish and am intrigued.  I am wondering if anyone has experience with either the SP10 or SP8 in a small room/near field listening?  @nonoise  , I am assuming that you did not pull the trigger on a pair, or did I some how miss that?

@immatthewj , You're right....I didn't pull the trigger on this one. I opted for something smaller and more manageable and couldn't be happier.

@nonoise  , what did you go with?  I am debating a speaker upgrade myself (I am currently listening to a pair of ancient B&W 805 Matrixes in a small room/nearfield listening) and I am constantly window shopping on the internet for possible options. 

While you're in there, install some .1uf or .01uf bypass caps, and let us know what you hear.

thank you, I am done designing speakers for good. I will just get ideas from this forum. -Andrew

@immatthewj  I went with the Revival Audio Atalante 3 monitors (w/stands). 

I don't see myself parting with them any time soon. 😄

Good idea, AJ. Your expertise pales next to the audio geniuses on forums.

McGowan is another one. I enjoy his posters putting him in his place on the PS forum.

@nonoise

Ignore him. He enjoys attacking respected members; probably because he knows he will never be one.

@deep_333 What a weird and stupid thing to say. A couple of positive things some members say about something and you troll it as a conspiracy and possibly gay?  You need to grow up some. This is not Reddit or YouTube, despite your efforts. 

@roxy54 I'd like to but he did need some dressing down.

@nonoise , You didn’t dress down anybody. Some threads just start to get just a li’l strange/suspicious from time to time, y’know. Dealers <---> " apparently respected members" backstage agreements and the like...

Here, scroll over to 5:20. I’ve known all about this phenomenon since the dawn of the internet.

Next, i might start linking a few specific threads and elaborate on where exactly they started to get just a li’l strange/suspicious (for educational purposes, would help out some unsuspecting audio enthusiasts).

But, sorry, if you didn’t fall in that category...Nevertheless, a guy is free to think his thoughts in this day and age...

@deep_333 What on earth does Mikey's experience with a dealer asking to sell his product and being nefarious about it have to do with a discussion about a speaker that audiopoint happens to sell? He was quite upfront about it all and merely offered advice. There was no hard sell going on. That's a hell of a lot of conflating and implying going on that simply doesn't apply.

But, by all means, feel free to think whatever it is you want in this day and age and carry on with the trolling. Dissect this thread and link whatever you think is relevant to your hearts content so we can discount it and move on with our lives.

All the best,
Nonoise

@nonoise 

You have to realize that this is the same character that called Ralph Karsten a liar regarding his experience as a musician and electronics designer.

Trolling at its best.

 

@roxy54 I've been staying away of late due to the declining civility here so I thankfully missed that one. I just peruse the threads, smile or shake my head, and move on as it can get too taxing trading barbs with ne'er-do-wells.

I actually feel better doing so.

"Have you ever upgraded coupling caps? If you know, you know.

Sounds like fun. I think some fail to realize that even the most brilliant designers/manufacturers have retained a bit of intellectual humility and recognize that their knowledge base is incomplete. There is always something new to discover. Secondly, in any commercial venture there is a finite amount of time and resources you can assign to a project before you have to take the D&E exit and go into production. Why not $10k a pair? Because "under $4k" would attract a lot more customers, and (arguably) provide more bang for the buck. So, you do what you have to do to hit a price point.

We may have just been introduced to an instant Hi-Fi classic, the best under $5k speaker ever produced. That being said, it doesn’t mean that with a little TLC, it can’t be improved. Or, have a blast as a speaker geek tossing parts around.

fyi- A while back I took a pair of AJ’s designed Pioneer SB-L22s apart and upgraded the crossovers to see how much music you can get out of a (at the time) $150 pair of speakers. Surprising. I also performed some serious upgrades to one of the most commercially and sonically successful speakers in recent memory, auditioned the finished product to the manufacturer and had some influence on their future "flagship" models. Even "classics" can be improved.

So, any first-hand experience with balanced/floating crossover designs?

I have diy’d several speakers and subs in years past. You could do that on simpler designs with no issues. Andrew Jones and his bottom end budget speakers (where he was literally given a 40 dollar budget to work with), for example....yeah, you can do some diy upgrades. Nevertheless, even Danny Richie got put in his place years ago by AJ on that lil budget Pioneer speaker. I’ll share that back n forth discussion, if i can find it.

On his 5k and above type of speakers where the dude had a decent budget to work with, especially the Elac Adante series, which i own...No, i wouldn’t touch that coupled cavity design of his. When that dude went into depth on how he modeled it, etc, etc before he even started to spec or dev any hardware, i was humbled. It ain’t all that simple as changing out a stupid li’l cap. But, then again, every forum guy around here is a freak genius diy expert in his own head.

On certain 20k, 30k, etc, clown car speakers designed by some "high end" dude, sure, no problem, upgrade away, fix the crap.

Yes. Me too. Not worth it. Professional trolls are …. just that. Trolls full time. As they say, don’t wrestle pigs in the mud. You will never win, and the pig enjoys it. Or something like that.
