right now i am using the Klipsch Synergy III 8" 2-Way Dual-Woofer for my center speaker, and for my left and right surround. i am using a pair of B-3 Bookshelf Loudspeaker, for my surround back.
for my left and right i and using the JBL sva 2100. and i have 3 sub-12 subwoffers in a room that 20 feet buy 20 feet
would it be beter if i used RC-64 Center Channel instead of the Synergy 3. and should i replace the old JBL with the RF-83 Floorstanding Loudspeaker
