my room is 1755cubic feet (13' W x 15' L x 9' H} my front speakers are klipsch rp-8000 center is klipsch rp-404c and my side surrounds are klipsch rp-500sa and my 4 height speakers are klipsch rp-500sa, my front speakers are 46 1/2" from both side walls and 46" apart. i know its not ideal but with my bed and desk in there its the only spots i can have them. i sit roughly 10' away from center speaker. So i was looking for a decent subwoofer maybe a 10" sub any suggestion would be appreciated price range no more then 700$
