Hello all. I have a RW-12D SUBWOOFER attached to an onyko 7.2 THX certified receiver (model 707)? I have been unable to get musical sounds from this sub. I am currently using an old Klipsch KW-10 sub, which I like and find very musical. I am using a single RCA plug to the L/FE port. The sub looks beautiful, but I am so disappointed in the sound. Friends that listen to it agree. I read where one owner stuffed the cabinet with fiber glass. Can the port be closed off to create a sealed sub? I am a music graduate from Indiana University, currently living in Ohio. Any help would be appreciated.
