Hi All,

I have the Polk Audio PSW125 subwoofer, and an Onkyo TX-SR875 as my receiver. I connected the sub with a LFE cable to the AV, but no sound is coming out from it.

At first i thought it is either the cable problem or the subwoofer problem, so I went to buy a second receiver(Yamaha) just to test. And sound did come out; this means the cable AND the sub works.

So my next assumption is the ONKYO receiver is the problem. So, i went to exchange for a new one ONKYO. Pluged in the sub and still NO sound.

Any suggestion? Is there something that i have to setup on the Onkyo? I made sure the 'subwoofer' setting is set to "YES" but still does not work.

Please help!

Thank you!
Joe
