Another price range than where you are but imagine a 5.2 system with 4 Klipschorns, La Scala II center and ...... Wait a minute, I don't think you need any subs if you have 4 klipschorns....
How is a sub even getting close to follow the efficiency of the Klipschhorns ???????
Efficiency is 105 dB 1W/1M, and then you have a 15" woofer in each speaker...
I don't think you can talk about any kind of dynamic compression around here
