Gerry S Posted September 17, 2012 Report Share Posted September 17, 2012 I know this topic will "raise eyebrows" because this is a "Classic New England Loudspeakers" forum. Some may feel Dr Hsu doesn't really "belong" here. But I disagree.I first met Dr Hsu at the Boston Audio Society when he was earning his Doctorates @ MIT. It was in BOSTON where he developed his first prototype subwoofers (HUGE 6' tall enclosures) in his dorm. Capable of producing pure 16 hz fundamentals @ relatively high undistorted SPL, I was impressed. I myself am not a "ultra-deep bass fan". When I heard them demonstrated, it made me "queasy" because 16 hz fundamentals upset my equilibrium for some reason.But I knew other BAS members who loved organ music. So, I encouraged him to demonstrate his "prototypes" at a BAS meeting. Members were so impressed they requested Dr Hsu build them "in quantity" for sale to BAS members. He personally hand-made the first half-dozen or so (can't rember the exact quantities) in his MIT dorm and the rest "is history".Dr Hsu has just hooked up his "mid-level" VTF Mark 4 along with a Pioneer VSX-821-K multi-channel reciever into my system. Both items sat there boxed for several months because I was too lazy to hook it up. They are used with my BA HD9's (my "submission" in the BAS "shoot-out" posted by Steve F elsewhere... "AR 4x competive with today's best".I don't know whether the Hsu configuration is "sealed" or "ported", or what the "specs" are (and don't care). I DO know the following: it contains a 12" driver driven with it's built in BASH amp. The Pioneer reciever has a built-in electronic x-o set to 80 hz (the built-in x-o in the Hsu sub is "bypassed"). Playing just music CD's in stereo only, I'm truly AWED by what it can do. Truly viceral with just about everything I've played on it so far!Only within the last two days have I played back DVD's in 5.1 using the Pioneer reciever (actually 4.1 because I'm not using a center channel; just the HD9's providing the "phantom center" when sitting in the "sweet spot"). The "surrounds" are modest BA HD7 "bookshelfs" I voiced but laying around unused; put these on stands @ ear level. Again, bass was ASTOUNDING on action blockbusters containing "LFE" material. Whether in "plain stereo" or 5.1(4.1 in my case), total system SPL cababilities far exceed what I can listening to comfortably (or getting a complaint from my neighbors or condo association) !!!I know there are some here who feel subwoofers in general is best for "home theater" applications; "problematic" for stereo playback applications. I have definitely found the Hsu subs NOT to be "problematic" for "stereo only" applications; quite the opposite. What's eating me away NOW is the the fact that I've know about Dr Hsu and his products since conception. Several decades later am I JUST discovering just what I've been missing all those years.So Dr Hsu's products may not be "vintage classics" of the AR3 era. But they definately are "New England" in origin. What do OTHERS feel about Hsu Subs (or subwoofers in general) in "stereo only" applications ?
