I recently purchased a new home and a new 50" Panasonic DLP TV. I am now upgrading my home theater system and just purchased a pair of RF 35 for the front channels. Great speakers,however, they are a little large for the room. My questions are would I be better to downsize to the RF15 and upgrade my receiver and subwoofer or save up purchase the RVX 54 and wait to upgrade receiver and subwoofer. My subwoofer is PSB 10 years old, receiver is Panasonic 3 years old.
