[quote user="Romy the Cat"]Yes, it was not “allergy” but already, the benefit of the automated check speller but it is not the point. It is not about lofty standards. This web site is not about offering help or imposing help. I do not mind to help pe...

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 ...

We have tested live recordings against live sound, a recording of a jazz singer was done on Reel tape on an Ampex ATR modded machine with Fluxmagnetics heads etc. The microphone used was the legendary Telefunken stereo tube mic. no post producti...

First let me say I am NOT trying to promote the Synergy horn. I just think it is very intresting to look at and to think about.Ideal loading only occurs at a singular frequency within any horn. This ideal loading point is where the length is 1/2 a wa...

Hello Romy,
I understand the difference between the kind of "basshorn" pictured here and the proper compression-horn that you use. It is true that many DIY-types like to make basshorns in their garage without much thought to technical consideratio...

Hi Roman et al!Allow me to introduce myself. I have followed with amusement Romy the Cat for many years. He is ascerbic and ultracritical, but he does know audio. We share many tastes, like the Koetsu Onyx Platinum foir instance, on...

Thanks very much for your prompt, courteous and informative reply!My thought about the crossover design for the EdgarHorn was due to a number of things:1. This particular EdgarHorn is being sold to make way for a Cain & Cain speaker which i...

[quote user="Paul S"] I am glad to hear that I am not the only one who is overwhelmed by compression drivers. I tried the A7s way back when they were current and everyone's favorite, and I tried various modifications with like-minded friends; b...

[quote user="hagtech"]Perhaps the book falls under the "theory of irrelativity". I thought maybe there could be a useful tidbit inside. One good thing about blogs - people may not agree with you - but at least you can safely post an opini...

There was yesterday somebody at the Audio Asylum sewers, asked about possibility of building a multi-way horn installation but he did not want to cut own horns. I posted a reply that the AA dirt of course was vandalized. I intended it to and replay p...

Well, it is always difficult to me to deal with audio people because any expressing any abstract notion in front of them those enslaved people perceived as a preamble to some kind of “deliverable good” and the sick audiophile imagination has already ...

Antonio,
Bruce Edgar sells an excellent all front-loading horn system, the Titan, which works well in small rooms. He will sell you unfinished horns, and you can find/buy the drivers yourself if you are a DIY guy, or on a budget. Considering the...

Well, since this thread is about the BMS drivers then what can I say? When I tried the BMS driver I felt that their “absolute tone” ability was at the level of demands of school auditoriums. Read more about “absolute tone” at:

Hello Johan, Great pics, the diaphragm appears really thin, almost like gold leaf for guilding...I have a question about the screw mount that Goto uses. Did you by any chance find some kind of flange (for pipes) that would work as an adaptor? Pe...

Recently, I was fortunate enough to have an extended listening session with the Living Voice Vox Olympian outside of a show environment. Since said listening session took place upon a boat – moreover, a wooden-bodied boat – under what can only be sai...

[quote user="de charlus"]Ok, understood, at least somewhat. Are you suggesting that the S2 operates at the frequencies between 1000hz and 3.6khz? I am not insisting upon using the driver at the frequencies that I was initially suggesting; far fro...

TH,this is very much NOT a DIY site. It is however probably the most complete collection of „SOUND as it is related to horns“ articles.I suggest that you check out things here first before asking „the wrong“ questions. The horn systems that you show ...

[quote user="Paul S"]...Certainly, in the end, I have "rated" my own systems on Musical "Satisfaction", which I put in quotes because what keeps my interest at any given point in time seems to vary, at least somewhat. Hard to imagine stopping on one...

[quote user="noviygera"]
For me personally, midbass is the most important frequency range when it comes to sound reproduction. I believe you will be on the right track to focus on this range because so often it is overlooked and treated with super...

Ok, Andrew, this is allergy something. I would highly advise you in future before you post any discrete updates, questions, and ideas about what you to inform about the holistic objective of your project, sort of a view from 50.000 feet...
