Paul, I am no expert on tapped horns but I think the main (40 year old) principle is that you join the back wave of the driver with the front wave, now in order to have the 2 wave fronts meet, the back wave should travel a certain distance depending ...

The closest to date I overlapped cones and horns myself was waaaay back in my time with Altec A7s. But I have since then and up to now heard many fine "hand-offs" from cone to horn, and my current project speakers hand-off cone to (very fast/short) h...

In our experiments, the more power we threw at the A7s, the better they worked. I heard some of the original "theater" version Altecs playing with their original "dedicated" Altec amps, and these sounded considerably better; but I never got ahol...

nope. i truly believe it to be one of the best and definitely without argument most innovative speaker designs ever made. sorry if you don't see that.you need to learn more about them tho, because you didn't even realize what drivers they used from t...

... to better express myself, with every needed nuance... Roman: I never wrote I'm able to time-align my speakers, I only told you I quite recently began "moving" drivers and horns as I never did in the past few years, NOT simply looking for a practi...

With near 1R impedance I
presume you will have multiple bass drivers paralleled. That is perfectly
legitimate way to operate but there are a few things you might consider. The mistakes at 1R are more effective then at high impedance.
If you have...

KOT, as you may know, the ML2 has a BIG transformer to make "36 Watts" at clipping; but even with this and the trick feedback it is not the first choice for large dynamic/OB drivers. Of course I mention this because of your remarks about the 6C33C, ...

Don't worry Romy, I know exactly what you mean. I tend to discount the opinion of anyone who raves about a system's ability to play back patricia barber. Speaking of which, if I were in her shoes, bunions and corns aside, I'd be mildly...

I appreciated a couple of things, probably for different reasons than Q put them forward, I think. For one thing, I more or less discount his timelines, and also the idea that certain audio components reached a high-water mark as "complete" achievem...

Ok, I blamed the tweeters and MF drivers now the turn of the MF horns. The Mid Frequency Horns (I’ll them “MFH” from now and on) are the stinky like pieces of horn installations, and if they are not done correct then they screw up anything big time T...
|
|
Like I said before, I found the silk domes best below the highest frequencies, just like your Vitavox, so it's another case of pick your poison. And I'm not sure about matching dissimilar driver types/efficiencies to mo...

OK, Romy, that EnABL stuff got my attention!I can't recall all of the bad ideas borne of good research, but this EnABL thing sounds a little fishy, and certainly it sounds too good to be true, as existing in a simple and really useful form. Can...

[quote user="Paul S"] I can report that the G2Si loses the "glycerin" at 10k with the ML2s…. [/quote]
I concur with this finding. Any ribbon tweeter that I heard has "glycerin" tone but it is because the ribbon mostly crossed too low. I would say th...

I am glad to hear that I am not the only one who is overwhelmed by compression drivers. I tried the A7s way back when they were current and everyone's favorite, and I tried various modifications with like-minded friends; but I came to the concl...
|
|
That just about sums it up, all right. You'd think it would be obvious that cartridges are not a viable subject for DIY/boutique building and/or modding; but, apparently, they are yet approached in this way by a small "underground" army of hopefuls,...
|
|
Romy, is there any way you can re-arrange tor re-configure the speakers in order to accommodate the stacked 15" drivers, or are you determined to push your speakers against the wall where they are now? I ask because I have heard stacked 15" drivers ...
|
|
Besides the single driver Aporia (which I haven't heard) I don't think Silbatone has made any speakers. So they don't 'employ' GIP drivers. I think GIP is a separate Japanese company who have just been invited to participate at these German show...

[quote user="Romy the Cat"]Here is the idea that I had for the “ultimate bass” for my room. Below is the picture of Macondo one channel as it is now from my listening position. So, if I find a way to deal with the wall edge at my ceiling then I migh...

Be, thanks for bringing up the "subharmonics" in the way that you have done, for another good look at the elusive-to-hi-fi "undertones". I have been bitching about and futzing with this for ages, and now am I working with the drivers, themselves, t...

[quote user="Paul S"]Again, I am NOT a collector - at all. I am only in it for the music[/quote]I am not a collector too. I collect some very specific drivers only to take some good parts out of them which are not available anywhere else. I do not c...

[quote user="cdwitmer"]Dear Robert and Roman,[quote user="Romy the Cat"]
To spending $40K for let it be even good single-driver loudspeaker is a summing of absurdity in my view.The Cat[/quote]For some people that is almost certainly true. But to tu...

I don't know why the Berning topic gets everyone so worked up. No need for another ZOTL screaming contest. Is this not a hobby where we explore many solutions? It is a difficult subject technically. I for sure can not speak about th...

Well, why not go 1st order with those little "woofers"? And I suppose you will be glad that you've isolated the MF, too.Unless you just get lucky, it looks like the MF/HF XO might be dropping. I am not familiar with the 2105, but dependin...

Maybe this is a mic problem, or a Sunfire problem. But, like I said way back when, the raised floor sink is not only the 5 Hz structural/footfall resonance, but it is uneven broadband + & - with respect to hi-fi, and the helluvit is that your ho...

Hi Cat,The more and more I listen to reproduced music, the more I realize dynamics and tonal respect are key to start any reasonable installation. This kind of crosses over into some driver discussions so bear with me...My Tannoy 10" ...

I have had similar impressions to other speakers using these drivers. For example I found the top of the line Avalon Eidolon diamond to be similarly colorless and lifeless. Also a pair of Vaic speakers (designed by the guy from Lumenwhite...

Ok, I ordered this a day before making the thread, and got them yesterday. These are overall the best headphones I've used, having neutrality, details, and natural sound. What's important to note is that when you touch the back or inside, you don't r...

"Vitriolic" is certainly the wrong word to apply to my "attitude"/post(s), Dominic. "Amused" is more like it. I am amused by claims that ANY 4" driver makes a stand-alone "Full-Range" speaker able to "presen...

Of course we do not defend or support a given topology itself but we only wrestle with the results we are able to get from it. Right? But perhaps there are some basics we can agree on? Basically, if it's Tone you are after, you are swimming upstre...
