My house is almost done and I have purchased or ordered the following 7.1 set up for a room 22'x18'x9' for 70% movies and 30% music use. TV - Sony 60" Grand Wega II (on order) Recieber - Sony DA4ES Center - Klipsch RC-7 Front L and R - Klipsch RF-5 Surrounds x4 - RCR-5 Ques 1 - I have done alot of reading on this site and I know that many movies do not go below 20 db but some do (AOTC). Is there really that much difference between the PCi and PCPlus models. Should my room's size dictate which of these two models I should get. Ques 2 - For my listening habits (70% vs 30%) should I invest in the 16-46's or the 20-39's? Any help would be appreciated, thanks.
