Acoustic Solutions AV40

i run these speakers on the surround channels of an aiwa system and i have the av120s on the main i know my main chanles are 150 watts each but im not sure about the surround channels but i know that these speakers are quite powerful at 100 watts each the good thing is that they are the same bass driver as the av120 so i know they will be able to take the power if i wanted them to the only difference they are a book shelf version of the av120 and have one bass driver insted of two i love them as they are ideal for surround sound because they can keep up with the av120 they are great
