The Nousaine quotes were all taken from an 11-page Nousaine article in the February 1988 issue of the Prairie State Audio Construction Society newsletter SOUND BYTES. The article was said to be a transcript of Nousaine's presentation to the audio club a few weeks after his AES presentation on the same subject.I can't find my 4558 preprint to quote from it.
If I wanted the loudest bass possible in my room, then one or more subwoofers in a corner with parametric EQ to eliminate all bass peaks at my sweet spot would be the answer. But my main speakers are 8 feet from the front wall and five feet from the side wall, so using a one corner subwoofer makes it sound like a bass player is standing alone in the front corner of my room!
Subs "stacked" in a corner may really be side by side in a corner rather than all stacked vertically to the ceiling.
All the measurements we have don't mean much if they are not confirmed by real audiophiles experimenting with subwoofer locations/quantities in their own rooms.
The ONLY conclusions I have from 25 years of experimenting iare:
(1) parametric equalizers are great "band aids" for subwoofers,
(2) a dozen bass traps are good if the wife will allow them (two don't make much difference), and
(3) side and rear subwoofers are much less likely to be sonically invisible than front subwoofers located near or between the two front speakers of a two-channel audio system.I can't even say for certain that adding a second subwoofer will benefit the two-channel sweet spot seat in a particular listening room, much less a third or fourth!
I'm sure "experts" who claimed the world was flat were cited many times ... before people found out they were completely wrong!
My current tube subwoofer places a 15" driver behind my left speaker, four feet off the floor, firing up at a slanted ceiling that is about nine feet tall above the driver. This location requires three bands of parametric EQ. If I reverse the subwoofer 180 degrees so it is downfiring at my cement slab floor, the frequency response becomes so bad that after an hour of trying to equalize it, I just gave up.
This worst sub driver position I'd found since 1987 ... was a mere 4 feet away from the best sub driver position I had found.
Who could have predicted that?Okay it's long past time for us to reverse positions and start a new argument. My new theory is that if your home has a street address that is an even number, then you should use an even number of subwoofers. I could cite many studies for this hypothesis ...
if there were any.
