Im replacing a older onkyo HTS-system 2 THX certified sub that came with a system I won years ago.. The sub had 2-12s and sounded pretty good... currently my TV room is about 18x12 and I like bass...lots of it.. watch alot of movies and listen to music mostly hip hop and then classic rock, metal....Ive been researching some subs and I am leaning towards the Klipsch R115SW, HSU VTF-15H-MK2, and possibly the Klipsch R112SW. I have not heard any of these nor do I know any place around my area where I can hear them... Does anyone have any experience or thoughts on these subs... or any others that compare.
