The best-sounding drivers I've heard will amplify a wide range of sounds from scratching or tapping differently at different points on the cone, or even from tapping or rubbing the driver frame. And never mind OB, some throw amazing tonal range and ...

My room, is 16 to 17 feet wide, 27 to 28 feet long by 12 to 14 feet high with all walls splayed, with a combination of absorption and diffusion on the walls. All electronics are fed electricity by three pure power units originally recommended by Rom...

[quote user="Rewind"]Hi, I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. [/quote] OK, but it is not how I feel about the service of injection...

After the painstaking setting up of the new Macondo, measuring all distance, paralleling the horns and time-aligning everything, after the setting up a correct level of the new channel’s attenuation (it turned out -2dB was necessary) I spent some tim...

Big 93 dB woofers with a "split" no-feedback SET?Perhaps if you re-think the LF drivers you might indeed start with a vanilla version/pair of the Melquiades, just to get a sense of what you're dealing with. If you are able to get or get a sense...

[quote user="Jeffrey Jackson"] Also, I had never dreamed of a driver with a variable compliance resulting in a variable free air resonance... such a toy would be wonderful with custom midbass and bass horns... [/quote]
It is why I use cone drivers f...

ML2 is also making me hear my modified AI M3A pre-amp, not to mention I guess I could now benefit from all shielded cables. All this stuff was fine with the Wright 2A3s. Speakers: I built a version of Dick Olsher's 3-way Diamond...

The thing I notice with live music is the way the sound at all audible frequencies has articulated drive like I never hear with "true HF tweeters", or at least not the "tweeters" that go way up there. I got some sense of this drive and nat...

Hi Romy,I have found that the Apogee loudspeakers ribbon drivers can quite successfully reproduce correct tone. The reason why is this: They have very little coloration from the driver materials themselves (no nasty resonances as the reso...

Andrey, I have seen the ad you have mentioned. A few things. Facebook is notorious for supporting fraudulent ads. I personally bought many things based upon Facebook ads, mostly stuff for kids, and never was receiving exactly what the ad promised. So...

[quote user="Paul S"]Amir, what you say and the simple way you put it is indeed a very important consideration for speaker/amp matching, and it is something that one must actually hear and cultivate in the first place. Since there is no way to emperi...

[quote user="Jorge"]I have seen Beyma rewrite their specs when they redo a driver and even add a letter to the driver for that change, even if it is the same driver.Now I have seen variable FS responses form different drivers of the same model also....

[quote user="Jorge"]One more thing about the JBL 375, I did play around with them enough, I aligned the diaphragms several times untill they sounded their best and were very listenable, This was some time ago now, I didnt turn my horns then, so I tr...

Of course I am not really talking about Rullit but only holding up his implimentations against his stated aims. This is certainly no special case, since most smart people learn the talk and the "look" long before they learn practicum, if they ever d...

Looking at Vox as a glorified 2-way Altec speaker with tweeter and supertwiter with all " not optimal" choices ,folded 70's PA thunderbolt mid bass cab time misaligned crap ( Romy's opinion ) bi-radial Vitavox midrange suitable for derby races and d...

I'ts not that I feel "someone else's would be more informative than Cogent". Rather, even though I know what I heard from the Cogent version, I cannot at this point say I understand how much and what part of what I heard is ...

Romy, I think I didn't explain myself very well. I was agreeing with you, and still do. I posted the Chris Widmer link to show that the same fanaticism is going on, but even more so, from the thread two years ago which you posted th...

Alex, contrary to the numerous speculation that many people more or less reasonably spread about the subject, my experience indicates that there are no such a things as “preferable crossover frequencies". The chosen optimum crossover frequencies are...

Hi Rony The only think a manufacturer has over the me is custume made drivers not saying that makes them better.Also you came up with a design conclusion and assembled you own system(That makes you a DIYer).You choose not to endores an...

Jorge, not to stoop to a shopping list, but I thought I also mentioned the 375 in the post where I introduced Rullit. Anyway, I meant to. Since there is no mention of the 375 there now, I will drop it again. This was the driver I lusted after in my...

Jessie makes an interesting point with the idea of trying to get ULF from 97 X 2" drivers. Very few small drivers are "optimized" to produce ULF in the first place, and so far the small-ish, BIG X-MAX drivers that are intended for "bass" have not be...

This there is the last in the “THE PROBLEMS WITH HORNS” cycle. The previous threads might be found at:
Problems with horns: tweeters.Problems with horns: mid-range horns.Problems with horns: mid-range drivers.
This would be probably the most contro...

Thanks for the link, Murat. I have seen the WE copy drivers before, but today I confused the 555 with the 750/753, etc. paper drivers. If the 555 sounds good over anywhere near its claimed frequency range, and if you are in a position to buy 2, why ...

[quote user="Romy the Cat"] Good question, HookEm. I would say my answer would be 2, “Any single driver back-loaded loudspeaker in general”. Do not get me wrong, driving your, or any other single drivers would do fine by ML2.0 and you will be able to...

[quote user="Romy the Cat"]our logic is correct but you refuse to see the whole picture - this is the biggest mistake the admirers of the open baffles do. Let trace the entire process. You grow the size of the baffle in order to keep the speakers to ...

I have heard several Tannoy speakers in the past, but have never heard the quality of sound Romy has obtained with his brain child. I don't know whether it is the speakers alone or his setup which has allowed his system to enthrall so much more than ...

After trying these reticulated foams for some time now, I ended up with using them only on the JMLC 1400 with the Radian 475 beryllium drivers. I had a smallish bump about where it worked. It flattened out and the sound changed a little. It sounded a...

Romy, of course I frame my remarks according to how I "understand" the issue at a given point, ie., dialog. If your response helped me to undersatnd your idea of this problem any better, then it seems to go back to the ...

[quote user="Paul S"]The frustrating thing for me while messing with the mounting screw tensions was that there was never a universal "best" setting that involved looseness, but it would all change with different sources or at different volume settin...
