Hi Gera"Has anyone done this and what were the observations of comparing different topologies."I have done just what you propose, I tried the JBL2490 compresion driver with a 3" mouth in a 110 hz horn well made, MDF round tactrix horn, it goes ...

I never hit such a huge jackpot as I just did with the Lavry DA-924. The most funny in that even that I did it absolutely blindly. I had some minor beef with DA-924 sound: upperbass/lower midrange and the slightly too much extended HF (very very clea...

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 ...

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...

[quote user="Paul S"] Speakers: I built a version of Dick Olsher's 3-way Diamond Edition BassZilla (hard to find at www.blackdahlia.com), and I tricked it out considerably from his mule. Bass is BR, 15" Audax P380MR, which is a nice semi-...

Your points about "better" versus "correct" and "tactics" versus "strategy" are well taken. You are pretty good at saying things I have thought about for some time but never articulated, perhaps because there was no one to tell. I ha...

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...

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...

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...

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...

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...

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 ...
|
|
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...

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,...

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...

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...

I have been asked by a number people who monitored my progress with RAAL’s “Water Drop” tweeter: “Romy was it worth it?” Well, I think after a year of leaving with tweeter, learning and satisfying it’s little habits I might pass some generalizing obs...

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 ...

The paper drivers, at least, look like the best of the vintage stuff. Of course it's hard to say without hands on how GIP products have translated from Vintage WE and, judging by the literature, either the "vintage market" is irresistable to them or...

Hi Roberts, Romy and others,Before this thread vanishes in undeserved obscurity, I have a question or two for you. I understand that the issue is a complex one and should be addressed with more care and paying attention to detail than I am do...

[quote user="Romy the Cat"]Rakesh, the people who read this site have bought Studio 8M many years back. I do not think you will find a lot of investors in this ides here. Also, the people who read this site are accustom to my very idiosyncratically-i...

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...

[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="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 ...

MS2, I certainly agree that the specific tweaks/changes you mention would/do change the sound from a given driver, along with myriad other "elements". Now, the questions and supposed answers included/implicit in your post make me think. While it is...
