OK, this morning I tuned the playback and did some listing, trying to understand what was the problem. Sound was not just bad but it was very strange, it was almost as a mechanical replica of sound. I took my phase meter trying to set horns in ph...

Romy,
>If Bruce suggests that his folded upper bass horns works better then his straight horn, and if it is correct (do not forget the he said about his horns), then it means absolutely nothing.>

[quote user="CO"] Ive been building and improving my own speakers the last few years and at this point i'm thinking a fully horn loaded setup ( 3 way + sub ) is the best route to take to get a speaker capable of faithfully reproducing the elect...

hi romy
idea of a 4way speaker system. not time aligned, but in compensation mid-bass horn and mid-high would create a one point source.
30hz - ~ 120hzBass cabinet similar to bassmaxx

[quote user="msaudio"]Your Typical Acoustical Suspension-type Loudspeaker enclosure witch has less then 90 db at 1 watt does not belong with a horn system that starts at 110db at 1 watt, even when you ad more then 1 driver, it is still way to far...

[quote user="RonyWeissman"]A mid-bass horn for my Altec 515-8G drivers operating from 100-600hz [/quote]
Rony, I think your wish to have mid-bass horn with 515G is a bit faulty. A mid-bass horn for 515G shall be 50-600 Hz. Let me to explain. T...

A visitor of my site sent me email with following:
“I take it you don't like the Rogero style (or Johan Dreyer) bass horns with wings, but you could add compression to a similar setup and make it work properly. I have made several design...

Finally, it has happened. Sound. Two weeks ago I had a couple of mates help me carry up and install the first DSET on its pedestal on the horn stack. It was quite a bit of effort and three were definitely required for the heavy but delicate operat...

[quote user="skushino"] Bottom exhaust.
Could keep it simple and fire straight down onto the floor. I think
there are benefits to adding a very robust floor platform beneath the mouth,
maybe with a reflector, similar to Bruce Edgar's Seismic Sub...

Hi Romy, I recently heard the smallest Cessaro and while I felt that the bass was not adequate for long term satisfaction it was also not a total disaster. From the midbass on up; however, the speaker is simply superb and one of the very best h...

2) I do not think that you will be able to time-alight the upper bass channel but you need to wave-align them. Make sure that upper bass and MF tit the top of the wave at the same time. the w...

I've had a long-time desire to replace my Edgar 80hz midbass shells with a better performing solution. My Edgarhorns arrived in 2005, and I made incremental improvements over the years until now they have little in common with the original Edgarhorn...

Yes, the topic is really interesting, at least to me. There is one thing
for sure – the man who starts the development of his acoustic system with a blank
sheet of paper, must have a lot of experience in arranging different channels
in terms of ps...

Do get an RTA, it is amazing how different the frecuencies are from what we imagine, 50 hz is very low! 150 hz is a vital freq, and a lot of female voices have a very nice fullness at 150 hz. It is hard to tell without measuring what is happening ...

Keith,
you see, in Alphas the MF driver does down to let say even 500Hz then it mans that they need to bring those bass W-bins unto 500Hz but it is imposable even theoretically. Let me to expanse, it I very simple. When a “reflected” horn fires up a...

A few things I would like to say in context of Pham’s playback.

None of the commercial speakers might relay on the Imbedded principles because the obvious reasons. They always look for as neutral as possible location because they mostly designed for anechoic operation. However, if the Imbedded techniques are used...

Hi everybody, after reading RomytheCat's Macondo Setup I am very impressed ( phantastic music room ...) . Presently I have no working horns ( they are boxed), just questions. First, Romy describes his horns as spherical. La...

Ok, I have been experimenting with placement : Long wall versus short wall. Though the frames have wheels and roll very easily, my room is cursed with an elevated platform smack in the middle of everything (about 14 inches higher than the main floor)...

OK, the new Macondo frame is over as well. Eventually after 6 years of learning how to make the damn horn speaker to sound good, after numerous incremental successes and failures, stupidity and brightness, moves to wrong direction and mistaken assess...

Kodomo,
A brief post about concerns. Feel free to discard it.
LF modules – are you sure that you want to go with ported
solution? You can model your boxes and use any good drivers but sonically with
port you will end up with bass that would h...

TwoGoodEars posted at his blog a report about is listening session or some kind of installation. I still have no idea who’s installation it is: Jean Hiraga or Be Yamamura. Nevertheless, I think it very much worth to look into it.

This is the text that John posted a few years back at Triode Mafia. John allowed me to post it here warning that he have learned more about tapped horn since then and hat his opinion might have changed since then. -- *****************************...

The best hi-fi LF I have heard came from modified "pro" units (multi-15s) that had a LOT of power thrown at them; and furthermore, the system was "managed" by an... equalizer (albeit, done in real time...). This is not to speak of its FR performance...

So, you use DCX 2496 for deals but not for crossovering and your crossovers are still on analog domain, right? Romy, I do everything in the digital domain so I use DCX 2496 as my crossover as well (but analog SS pro amps). I know you're no big fan of...
