I keep receiving those emails when people complain about the ballooned publicity and stuffed reputation of Vitavox S2 compression driver. I completely agree: the Vitavox S2, in the way how the Vitavox originally used it in their speakers and in...

[quote user="el`Ol"]I think they could could make the sound more pleasant with an overkill of second harmonic distortion. But for people who prefer that kind of sound a relax-horn like Anima would be better anyway. No real solution. Maybe they should...

[quote user="Paul S"]Romy, when you mention "dynamic sinking" of ribbons are you speaking of sub-8k Hz use of powerful ribbons like the Water Drop compared to 109 dB efficient compression drivers, or do you notice this dynamic sinking no matter ...

Hi Mats,I am not using 4 on each side. I will be using two on each side. Until now I always liked sealed enclosures. However Tad drivers are more suited to ported configurations. If you do not push them to go too low and have a reasonable fs point, t...

The way I would handle this is make my own 4" exit compression driver. What I mean is select a woofer with known good sonic qualities that match your requirments. Then make a phasing plug for it. My past attemps have been decent. However, I have noti...

I have written in past about my lack of love to the BMS drivers. The crazy, as far as I concerned “annoyingly wiling” angeloitacare brought this subject to this forum while he was galloping across Web, “picking from graves” about his new dB-Design’s ...

[quote user="Jorge"]I guess it would be simple enough to add a couple of inches in order to bring the throat down to 4" in order to try the Studio 8M. I have already reduced it temporarily to 3" in order to try the JBL 2490h compression driver. ...

Oliver,
It might be anything including electricity. Generally compression drivers are very much vulnerable to the electricity problems, muck more than convectional drivers. Let pretend that distortions in powers lines are responsible for worsening o...

A Netherlands company that makes loudspeaker of the color of lesbian solidarity announced their flagman model: Euphrosyne.

[quote user="Romy the Cat"]So, if the Ultimate MF Compression Driver is used from 1000-1500Hz then why shall it be able to play 500Hz? The answer is: he harmonic reserve – the driver that will be suited for 500Hz will have larger cone and softer sust...

Coops, I less care about the attacks on me, I know that I am a pH-indicator of Moronity among audio freaks. So, if some specific idiots out there are not happy about me then… it is good for me. The higher we climb in mountains the stronger wind and l...

It is not US’s Fox News and not Stereophile and there is no need to pull the fractions of "stupid" soundbytes to prove any agendas. Anyone whoever are frequent this site know in context of what the said was said. Most important that I know what ...

Of cause it shall be mentioned in the context of thin there that there is always the ALE Acoustic solution. The Japanese ALE Acoustic make two midbass drivers: P1260 and P160.

Yes, Ric, thanks for posting it. I have seen it a few years back, in fact I was searching for the images but was not able to find it. I think that fellow was ether Japanese or from Sound West Asia, I do remember already. It looks like it is 20-3...

I was thinking about the throat of my hypothetic midbass horn. This is complex, controversial and it has pretty much no answer, at least in the formeat I ask it. I will share my thoughts with you. Let pretend that I went for exponential midbass profi...

I thought of filling with sand braided multifilament nylon cable sleeving (http://cableorganizer.com/nylon-multifilament/) which comes in 2 inch diameter and does not expand enough to allow coarse sand to come out. It can be wrapped around as densely...

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...

Petar, wonderful observation as usual. I would like to add one factor that is always there but practically impossible to consider predictably. Any driver has suspension (with exception of suspension-less drivers that are not suitable for bass) and th...

The EV 350 cones are still available form many sources, they are $25 per cone. There are some other phenolic domes for 1” driver, or smaller. I do not know anyone who does 3”-4” phenolic domes that would make them suitable for MF drivers.
As far as ...

That was surprising to hear the Firebird complete Ballads in CD conducted by Dorati I can be sure to say it was mastered perfectly and no compression ever used ... If anyone is interested in Stravinsky Complete Firebird work should get this on LP or...

Sorry for making that video so large. Here it is again but 1/10th the number of bits. Compression can be a useful thing.http://www.hagtech.com/blog/media/6c33.wmvjh...

Taming strange fullrange drivers is fun, doesn't cost an arm and a leg and there is always room for a second, third, etc. system. E.g. what to do with such a ridiculous unit? http://www.ciare.com/pdf/catalogo/HX135.PDFBack-loading? No problem when th...

The thread is derivation form the previous thread about the Dima's amplifier.I was trying to gradually approach better and better loudspeakers with the Zarathustra amplifier but today I decided to hit with the Zarathustra the pinnacle of low sen...

there is one system that resembles what live music sounds like and its not a horn! :)To be honest I really have no idea of what topology these horns were setup like... all i have evaluated is there soundI like to go into something without any prejust...

Romy, I think you have neither a system with back chamber now (because the foam is closed pore), nor a "true compression driver" (because the foam is not rigid). Probably you mainly have a second vibrating system coupled to the cone that enhances mec...

Oddly the seller has removed the images of the wood horns as well as the mid bass compression drivers. They are still illustrated in the plans. Great looking horns. Perhaps he sold them. They where 150 to 5k drivers. I think Jeffery Jackson probably ...

... so the new drivers, particularly the S2, may not be such a bad deal given the price of older drivers. The woofers would probably be less of a risk than the compression drivers, and at least new cones and bits and pieces are available. ...

If you one of those who feel that playback make difference then I do not think that better playing of Bruckner music would require any different playback efforts than an y other better playback. Still, practicing “better playback” and loving t...

Two month back I stopped to use Pacific A/D but yesterday, experimenting with some exciting things ( I will tell later) I discover a very interesting configuration in which Pacific is free from small compression problems that I reported before. I was...
