The last time I listened to this was before I downsized my system. We listened to it in 2.1 mode on a set of Infinity Delta 60s bi amped with 2 Carver TFM35s bridged for the woofers and 2 carver M-200ts bridged feeding the midrange and tweeters in each cabinet. for the .1 it was a pair of 18" pro subs in a IB configuration feed by a Soundcraftsmen pro power 3 with updated power supplies and some other goodies, bench tested at 380@4x2. You could watch the windows bow in and out when we cranked this up and the big tubs on the bottom were hit! I miss that system. Total power output 3720 possible watts at full bore.
