Vandersteen Quatro CT or Wilson Sabrina

I assume you mean Eva Cassidy.  Heck, I cry every time I hear her music and then remember what happened to her.

yes, the one and only

@tomic601 ,
From my experience with the 2wq subs in my home, I do not find the bass notes traveling beneath to the basement, so unless your condo is built with minimal insulation, I think you wouldn't incur the wrath of your neighbors.

when the new sub comes out...i might try one...

i put 4 mm of cork/ sorbothane down over the concrete floors....

see Casa Pacifica system pictures..for challenge of sub placement,  but right now the sould is sublime....

@tomic601 I have two 2wq subs. in my system and my family used to complain about how they could "feel" the bass upstairs (I am in a dedicated basement room). After looking into the idea of decoupling my Treo CTs and loving the results (clarity, openness) I ordered giant decouplers from Herbie’s for the subs. Wow! The decouplers raised the bottom firing subs. about 1/2 inch off the carpet, yielding what my ears perceived as a cleaner bass response. The most astonishing result was I can play Donald Fagan’s "Morph the Cat" at volume, go upstairs and not experience the bass at all, and that album has kick-butt bass. Huge deal. If you take the leap into sub-land maybe that would be a good solution for your living concerns.

Here’s hopin’!!
