So, 15 months later and I'm still messing around with my sub setup.
Anyways, I know this is a really old thread....but it's really, really
good. I had forgotten most of the great info provided in here by the AVS Elite.
This weekend, I plan on trying some new sub positions (I have 4 PSA XS15s) since I finally got a laptop with HDMI to run REW the proper way. I've tried just about every combination of placement options possible in my room the past months (2 up front/2 in back, 1 up front/3 in back, all 4 in back spread out, all 4 in back/2 stacks of 2, etc.), but the one I have never tried is all four up front in 2 stacks of 2 (only way I'm gonna fit all 4 up front, but they can't go in corners - Klipschorn FL/R). As alluded to in Bill's last post, this may just be the way to go in my room!
My best response so far has been 2 up front/2 in back, all subs about 36" from their respective corners. This gave the best response and smoothest bass, but I was left wanting for just a bit
more headroom - placing them all spread out along the back wall (with 2 in corners) cured that, but I don't think it sounds as good.
My question is for Bill: in your post above this one, when you say "If the rear wall is a full wavelength or more distant from the LP", at what frequency?
In my room, the rear wall is only more than a full wavelength above 57hz (20'). Does this mean I would benefit from all subs up front or not? Also, my room is completely open on one side to another 2500 cu. ft. (total of 4900),how would that affect this theory?
To you people who hate it when guys bump really old threads:
To all you multi-sub owners who haven't seen this thread: you're welcome!
