[quote user="noviygera"] I think clearing this up this may be of benefit to other users who are building multi-way horns.Let's say I've got two horns mounted on a frame. There's a high horn above and a mid horn below and they are physically time alig...

Yes, the tamed beast is an oxi-moron. I thought of my 808s as ragged, rough (grainy) and spitty, while the S2 was also ragged/uneven, but the roughness was more like the sound of a metal zipper. Anyway, I never heard either of these stock drivers m...

Ok, since you people stop to drop the euphoric saliva around the Goto subject I think it would be worth to outline my interest in Goto. Not only worth but I kind of feel an obligation. I feel that my site surprisingly has become a resource that ...

Hello everyone:Fane Acoustics has agreed to produce a limited run of the now discontinued Fane 8M Studio drivers if a minimum order of 50 units can be filled. I am looking for firm expressions of interest for at least 22 pairs of drivers. If you are ...

[quote user="Romy the Cat"]I am glad that Fane “now found … that they have sufficient old stock of the 8 ohms or 16 ohms voice coils to”. Such a phenomenal discovery of the British archeologists. Can you ship them here in US, they can help us to fin...

I am just reminded of the long-since-superceded (naturally...) 10" Tannoy "mid-field" "pro" monitor. I think it was the TM10, which also used it's cabinet to very good effect, at least in terms of voicing. You want "bubbles", I...

Again, I am not insisting that the material of that horn will behave like a bell so much as I am suggesting that bell-like sounds will eminate from this horn. Is the difference clear? Some of those Altec horns were textbook exam...

As I learned today the Australian Martin seddon know as the Azurahorn Guy has a web site and he also does horns:
http://www.azurahorn.com/azurahorn_tradesecrets.htmlFrom Martin’s site:Azurahorn is best described as a long term audio project, funded ...

Romy, Our bass driver has a 12v field coil motor, it developes just over 20 kilogauss flux density using a low carbon steel pole piece. The exit diameter is 4 inches at the moment. The diaphragm is 6 inches in diameter and mad...

Romy,you did not disappoint my expectation in your reply. Who can argue with the take: "bugger off and do some home-work"? On the other hand, when looking through that "Knowledge tree TM" it's more of a "forest" as far as horns are concerned. So it's...

Similar experience but I get to keep my "old" room. I have just changed my 5 way horn loaded down to 140 hz speakers to a friends room twice as big as mine, with an open back area into the house as your new room has and one side and the front have hu...

[quote user="Romy the Cat"]I woke up and thinking about the horn problem with fresh head I am thinking what did wrong. I did not measure the frequency response of the horn – I did not see a need for it – the sound of the thing is way beyond where it ...
|
|
[quote user="JLH"] In addition, the idea of an ultimate horn profile does not make any sense. Each and every horn profile has its own strengths and weakness. Depending on your goals, and the drivers you have, one profile will be "bett...

[quote user="noviygera"] Vasyachkin, if this is still relevant:I've tried dipole bass and dipole mids with horns mid/highs in my system. If anything, dipole works the WORST for the bass and here's why:It does not load the room with bass pressure (or ...

Ok; there's a mis-print somewhere, or a manufacturing change... The web site linked listed SG-370 as 23,000 gauss, and SG-370DX as 24,000 gauss. The goto brochure lists SG-370 as 24,000 gauss. And was discussed yesterday w/ someone, one doesn't re...

The more-driver/more-power method has in fact been used to very good effect in rooms that +/- eat bass. The set-up I remember had about 8 515s per side and LOTS of power that I suppose it did not actually use very often; but it did provide nice,...

hi! Funny... i just passed it in Munich yesterday. Now its mentioned here. Of course i had to stop and have a listen with such cool look. Sorry to tell you, that things a imposter. I left in less than five minutes. It hurts my ears. Totally cold, sha...
|
|
Jessie, as it happens, I find my own best listening position varies somewhat these days, depending on what I'm listening to or for. For the best overall energy in my fairly energetic room, it is with my ears about 1 1/2 m off the...

Yes, for practical reasons, one side of an IB driver is usually "wrapped and sealed" to deliver lower frequencies from the other side, since it is generally impractical to actually make a baffle large enough to prevent sonic shorts. However, at high...
|
|
Dear Harlanov,For me the most impressive thing about this driver was its ability to simultaneously render soft/crisp sounds of similar frequencies distinctly, without muddling or other compromise. Additionally, at low volumes musical detail was not s...

[quote user="Romy the Cat"]The whole point in a compression driver is that anything in back chamber is irrelevant. [/quote]Hahhaha, good joke! :-)[quote user="Romy the Cat"]Haralanov, all that you need to do is to make your own experiments, the pract...
|
|
Mani, that "loaded OB" is an interesting approach to lower frequencies. IMO, the back waves from good direct drivers are under-appreciated. What do you think of the musical character of the LF you are getting with your system? Is it consistent from ...
|
|
Thanks again for further explication, Bill. I appreciate that you are heavily invested in all this. Taking into account not only what I have been told but also what I've heard for myself, I think I can squeeze a bit more soundtage from my current set...
|
|
Bill, it sounds like you have made a significant investment (time and resources) into (re)producing reverberation with your entire system, also setting time alignments of various drivers, across the board, and I assume you would not have gotten this ...
|
|
Amir, I have shared that I quite liked the (original) Audiopax amps I have heard. Whatever they claim, they do sound right to me. Although I have never played much with a de Lima amp I have played quite a bit with most of my own phono stages, pre-amp...

Haralanov, Yes and no. Of cause no one would deny the benefits of ULF reproduction but the key questions would be: 1) what kind of reproduction? 2) how to talk about it? There is no language to convey the ULF message. The 20K repose is meaningless an...
|
|
Was invited over to Romy's today for a listen. In the last two days, he made several small but critical changes in the time alignment, crossovers, and room damping, and the sum of them has brought his system up by several notches producing the best a...

One funny thing about "dynamic range" is that different audio camps claim to desire and get some form of "improved" "dynamics" from their respective, widely differing topologies, from panels to single drivers, to plasma, etc.Maybe they don't claim to...

Although Levinson appears to have missed the boat with respect to musical content, he did show what can be done with Sound, per se. I still use his demos as a sort of mental yardstick with respect to the quality of the sound he did "reproduce".With ...

Rakesh, I have a different approach. I feel that all communications are in a way worthless and I personally feel that I have the best education for myself when I experience an “offensive“ presentation from audio and THAT makes me to think about drive...
