I'm new here. I have a budget setup in my garage. Yamaha receiver, Klipsch quintet, was using a cheap Sony $160 sub which filled out the low somewhat but I want something with a little more punch for $400 or less. I picked up an open box Def Tech Pro Sub 800 for $360 And I have to say I'm impressed for the size. They have the Klipsch RSW 12 for sale for $350. I'm guessing there's no way an 8" can outperform a 12". Anyone here have any feedback/experience with both of these? Thanks in advance.
