Wow, didn't I just do this? For all the tedium with directed listening to a de-constructed system, 2011 went by in a blink!This has been for me The Year of the Driver. Much learned, and much yet to learn with repect to choosing, modifying, combinin...

So I am currently working towards this concept for my Macondo (see below) and I have just the Upperbass horns left to turn and prep. I am thinking about how to best integrate the DSET with Macondo and have come up with something like this… Perha...

Surely one of the objectives of this site is to allow people to be guided towards good sound by discussing the issues involved in getting there. Whether that entails discussing the merits of different recordings or performances or whether it entails ...

JJ, I not only loved the bass from the ML2 (SETs) but I loved the bass from the little Wright WPA 3.5 SETs! In fact, I loved everything about those amps, as long as they were "comfortable". Too bad that wasn't FR, etc. with my speakers...in my own ...

Hi, WojtekI get lots of PM from readers of this site; it should work. Try again, and be careful with the spelling, etc. Though I can easily upload pictures to GSC Image Gallery, I can't seem to get them from the Gallery to the Board. Perhaps they ...

[quote user="Paul S"]Thanks, Scott L. I get the math, and no doubt hearing is believing. Still, I do know for certain that "a driver" can be influenced by a defined amount of trapped air in an enclosure, at least as far as the sound that comes from ...

[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...

Well, FWIW, my Audax LF units started life at ~100 dB and wound up closer to 96 dB to get ~40 Hz from them via ~ 4.75 cu. ft. BR boxes. Computer tuning was very close, only a strip of rubber weatherstripping in the vent opening between be...

Well, Yoshi, at least you're on your way to getting your speakers more of a piece.I have for some time warned people against a mix-n-match approach with the DEBZs, based on my early experiments with them, and it is true enough to say, I think, that&n...

Yes, the "bottom drops out" of the "IB" depending on whether or how it's "opened", and one way or another, the cabinet may or may not "assist" the driver at some point. This is where one has to decide how much to ask from the particular driver or dri...

[quote user="Jorge"] I have never found the law of diminishing returns to apply to audio! Going crazy always sounds better… [/quote]
Jorge, we need to have a perspective about those things. With exception of oxric’s episode, who still is not...

At this point I think that the main advantage of efficient speakers is that they represent the best chance for a sort linearity that to my knowledge can't be gotten any other way. It seems like inefficient drivers simply do not sound the s...

Greg, do you have any experience with the Eminence drivers?When the Audax PR380M2 I use (8 Ohm) became unavailable, Dick Osher specified the 15" Eminence driver as a drop-in substitute for the BZ series.I happen to use a single 15 " Au...

We enter a complicated region as the lower driver we go the drivers could be used for different purposes and it is very hard to generalize. A 10-incher might be MF driver and LF driver. In my past I experimented with few MF 10-inchers, including some...

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 ...

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...

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...

Preparing for my Midbass Channel projects

…I did inventory if the drivers that I might use for it. I never did it before as the all were in different storages, now they a...

[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 ...

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...

The big RCA field coil is the best thing about the Cogent system. It has great "promise", based on what I heard. Although their methods of "developing" this driver seemed confused to me, they do have truly encyclopedic knowledge...

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 ...

[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...

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 ...

[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...

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...

Jessie, your post catches me thinking about multi-channel driver matching, as well. I am not familiar with the Fanes, but I wonder if simply throwing more power at them would make them nothing more than louder, so they would then "match" the res...

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...
