I'm looking to add a subwoofer for my secondary system which is used daily but for casual listening only. Its not my main system. I have two speakers left over from a Technics Home Theater system that can play pretty loud but are all midrange/treble with no wait whatsoever at tthe bottom end. I'm looking at this sub model from monoprice which seems to fit the bill. Has anyone heard it play or have it? What are your thoughts?
