I have a 2 Year old PSW110 sub connected to a HK avr335 receiver. I have just noticed that the sub makes minimal sound. I have the volume up all the way on the sub and the output for the sub at +10db. The sound is faint from the sub. All my other speakers work wonderfully. I have hooked up an old kenwwood sub (the sub I replaced with the Polk) and it works fine.
what are your thoughts? I don't have my receipt and did not register the sub. If it needs repair, will it be cheaper just to buy another or actually send it in?
