Gents and any Ladies if present: My configuration is as follows: *65" Mits HDTV Integrated *Onkyo TX-SR800 RCVR *AR Status(Decent Line) Center, Tower Fronts, and Bookshelf Surrounds and Rears *JVC XV-FA900BK DVD Changer *XBOX My sub is an Infinity 12" from a HT in a box system, and I want to upgrade that portion next. My usage is 60/40 HT/Music(most music is DVD-A, so the sub is important). I am looking for THX Certified depths(around 20+ hz), but can't necessarily afford a sub at the THX price. I would like to know if I would be better off going with (2) 10" subs daisy chained or (1) good 12"-15" sub. My room is approx. 15-15 with 9 foot ceiling, but I am moving in the next few months to Columbus so I guess room size is TBD still. Please share your experience though with whether I should go for 2 or 1, and also please make particular sub suggestions also. I prefer tight bass to boomy also. As always thanks in advance for your help, these forums have become another obsession almost equal to my HT.
