You guys can argue back and forth as you wish. I visit here as I like to hear the different viewpoints. I monitored this forum for a few years before I even signed up, and rarely post unless I have a problem or need some advice.
HSU makes some excellent products. It it would fit and I could bring myself to spend that much, I would love to have a pair of USL-15s. That choice is already made as they are an inch too wide and two inches too deep.
The PSA is the only 15" sub that will fit under the tables unless someone knows of a 15" that is basically a 17" cube (including grill). I sent Beeman a pic of one of the tables, so he knows what issues I face fitting a sub underneath.
I am committed to the current placement, as I see this as the best option looks and sound wise. I'm open to other suggestions for a sub close to the output of the PSA, no larger than the PSA, and similar warranty and CS. Right now I am only seeing one other sub in the running and that is the SVS SB12. Same warranty and nobody can complain about the quality (and cheaper than the PSA as well). I don't think anyone can argue that the output is anywhere close to the same though.
I have a good month to llok for other options as Tom V. has told me there won't be any XS-15s in stock until late September. He has already impressed me with his quick responses to my emails, so that's another point in PSAs favor.
