depending on your setup $2000-$4000 for the speakers (5.1/9.2/multiple subs ect)
The setup i was considering was:
BIC AMERICA ACOUSTECH series
SURROUNDS: PL-66 (4)
HEIGHTS: PL-28 0r PL26 (2)
SUBS: PL-200 (2) & possible 1 or 2 more that can reach lower bass extension <15Hz
Heres the specs for the tower:
