Subwoofer problem

Babulas

Hi,

After calibrating my HT set up using Avia II and using my system for a while now there is nothing coming out of the Sub.

Light in the Sub in on. Cables are fine. Set up in the A/V is fine, including crossover setting at 80 Hz and channel volume. Volume in the Sub is ok. The Sub is less that a year old. The only thing unusual was the wife setting it on one of its side while trying some re-decoration.

I think I have tried everything from my end. Can it be the A/V not properly sending a signal?

Easiest place to start (if your AVR has pre-outs) is to turn the crossover on the sub all the way up, set your front speakers to large (in the AVR) and plug the subwoofer into the right or left speaker RCA jack.

If you get sound, its a setup issue. (probably in the AVR) If not, it may be an amp issue in the sub.

(edit - before you do anything - I assume by nothing you mean - no signal at all, not just quiet. If you put on a bass heavy scene does your woofer move at all? Can you feel it move?)

Try something in 5.1 with alot of LFE. Some AVRs have settings so you get no sub in 2 channel or Stereo

McLoki,

No sound means nothing at all. A good example is the beginning of Toy Story II. You can feel the windows rattling. Now you don;t feel anything.

I'll try what you suggest. I imagine you mean the left or right RCA located in the Sub.

If I understand it, since laying the sub on its side it has not worked? Maybe the magnet shifted or a solder broke on PCB.

DO you have a spare sub laying around you could try or borrow?

SOmething changed to make it stop working, sounds like laying it on its side is to problem.

Nope - right left output on the AVR. (instead of RCA or sub out) Basically I am trying to make sure the sub is getting a signal to reproduce.

Problem fixed.

I turn off the master Power on/off switch at the back of the subwoofer and used its microphone to recalibrate and things are back to normal. I did this after trying some of the suggestion above. So it was not the A/V not sending a signal. It was the subwoofer that for some reason wasn't processing anything. Thanks anyways.
