All - looking for some subwoofer advice as I build my system. I'm putting together a home theater/music system for a 15X20 room wiht 8' ceilings. As my mains, I have LSI9's, LSIc Center channel and LSIfx for rears. I'm going to use a yamaha RX-V671 reciever with an Emovita XMA 5 amp. As for sub I'm looking at Polk (keep it in the family) DSW micro 1000, SVS, or Velodyne.
Any recos on sub beyond that? Any input on those 3 as to what rounds out the LSI9 bottom end? Looking for a good performance/value mix to get some nice deep tight bass.
