Another vote for SVS - I just finished tweaking my SVS PB12+/2 with the SMS and now it's just perfect with my 10T's.
Aerial SW-12 or Von Schwiekert VR-S/3
To fill in the bottom on a 2 channel system. VAC Ren mk 2 pre, Atma m-60 amps, Merlin VMS-MMs. Will use Velodyne SMS-1 for room equalization upstream of the sub. Any thoughts?
