I just received my sub this last thurs. but was heading out of town for the weekend so i wasn't able to to do anything with it untill today. I have an older entry level Onkyo receiver (TX-SR500), a pair of RTi8's, and my new sub which seems to have a problem due to hardly any sound coming from it. I tried every configuation i could think of on the receiver and nothing made a difference. I then decided to try it with my brothers receiver in case i had a bad subwoofer-out jack, but to my dismay no luck with his either. So i'm gonna be calling them and seeing what my next step is. I hate to be sending it back being as i waited about a month and a half for it and now this. Anyway i posted to see if maybe anyone else had the same problem or knew something about the receiver or something else i didn't, that i could try.
