In the Thread: Hmmm... the sad truth about BMS..
Post Subject: BMS, DB-design and the reference points of “absolute tone”.Posted by Romy the Cat on: 9/17/2006

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:

What is important to understand that “absolute tone” has little relation to amplitude deviations and in the drivers even with 12dB jump the presents of “absolute tone” still breaks through. It is like a nice looking woman – no mater how ugly you dress her -  her attractiveness still cracks through all external "impediments". 

Someone at DB Design forum (http://www.bd-design.nl) after reading my negative comment about BMS suggested following:

“All 'n all his expression about the BMS driver, and listening to Bert about this earlier, is true ... when not applied properly in the horn consistently, and with the appropriate filters and some tweaks.”

Yes, this person partially is correct: if we spend time to work with drivers then we can get out of them much more. However, there is no known to me filters or tweaks that would make a driver that has no “absolute tone” to get it. Change magnet? Change a diaphragm? Change suspension? I do not think that they do it and if even if they do then there are more fruitful driver-candidates to do it. I would not even mention that I have no idea what “applied properly in the horn consistently” would mean....

Frankly speaking, I do not feel that DB-design folks actually know what they deal with. Well, they know that they deal with "facilitation of knowledge” for DIY-minded community but it is fa undamentally faulty objective “to get Sound”. As I can see, DB-design attempts/designs are juts not even a “half-ass” but “128th ass” efforts that DB-design hides under mask of humility.  Nothing wrong with it of course but I it is a too simplistic way of thinking on the subject of Audio. This simplistic Sound that they det is a direct result of their simplistic thinking... Perhaps it sound too arrogant but arrogance and continence are the similar worlds and they distinct only in perception. I have head what BMS drivers did tonally and I have seen how they converted all tones into a TV with high B/W contrast but low color saturation screen. This all, as I feel it, give me some right to me very arrogant, something that I never refuse to do…
