Subwoofer isn't working properly-help needed.

TTran

Hello everyone,

I am new to this forum. I have a Polk Subwoofer PSW12 hooked up to a Onkyo TX-SR702 receiver. I noticed today the bass isn't hitting as hard like it used to.

I tried turning the volume on the back of sub all the way up and there's bass coming out but is very subtle. I checked all the connections and everything is hooked up correctly. When I unplug the sub cable then plug it back in to the receiver, the bass sounds good when the connection from the cable touches the outside of the plug. I did a speaker test and the sub also sounds good, but during normal use of watching TV, listening to music and gaming.....it's like there is no bass at all. What's going on???

Any feedback would be appreciated.

Thank you,
Tran

Im assuming no settings have changed on your AVR, aside from possible sub damage, have you tried a different IC?

Oh yeah...welcome to CP!

It sounds like a bad cable, make sure the metal part(connection part) is not pushed in to the point that it's touching the metal on the back of the sub or receiver. If it's not that, then the RCA(sub) connection on the sub or receiver may be shorted out? Let us know what you find:)

I think it may be the infamous Onkyo Double Bass scenario. My sub did absolutely nothing outside of test tones until i enabled that setting when i had my Onkyo.

Thank you everyone for your responses. I will have to run out and get a new sub cable tomorrow. Does the quality matter on sub cables?

Sorry for this newb question on cables...is a digital coaxle the same as a sub cable?

Wow! Thats a question you may get 1000 responses for!:p I would pick up a good quality cable locally, see if that helps, if thats the cure, maybe order 1 from Monoprice, Blujeans etc.....

As for your question....a RCA cable will work.

I with knucklehead on this one, just try any RCA cable, and then get a better one later if you determine that IS the problem:)
