After spending about a week tweaking my new onkyo tx-nr5009 with setup in signature, realized i need a actual sub or two small subs. I'm happy with my deftech 8020 towers and 8040 center. But I'm missing out on the real low frequencies. My powered 8020's are only getting down to about 40hz according to Audyssey and I rather just leave them be as good towers with the xover at 80 on them. So, being I have XT32, my choice is get two smaller subs or just get one larger sub and put it in the corner of the room. Room is a open family room, figure 16' x 22' in the actual listening area. I used to run a 12" Infinity BU-1? in the corner with my Beta 50 towers and it sounded pretty darn good. Trying to do this on a budget of some sort. There is a local guy on craigslist selling two Klipsch 12" Synergy subs for $600. Actually found a post for a 6mo old Definitive Trinity tower for 1,200. Let's see what you guys think. Instinct is telling me to try and get the Deftech Trinity tower for 800-1k if it's a real post and checks out.
