Right speaker perfect. Left speaker sounds like someone is talking through a kazoo.

search for a good local amp repair service.

Turn up the volume on the left or right speakers or turn down the center channel volume to meet your preferences. There should be a setting for that in most receivers.

If your subwoofer is placed to the left side try moving it to the right side or try to move it in the center. Otherwise if you are using a PC go to the control panel and click the sounds and audio devices icon. a little window will pop up and the button labeled speaker volum click on and reduce the volume for the left speaker and then turn up the volume on your speakers and see if that helps.

I just want to confirm that the solution on another page from francis 8 works perfectly ( http://www.fixya.com/support/t3709832-speakers_stopped_working_cannot ). We have two sets of Creatures in our offices, one had been shelved (by someone less persevering than me) due to this problem years ago and my set started this trouble a few days ago. Troubleshot everything, every cable, setting, combination, spare speakers etc - nothing worked. Opening the offending speaker and pulling back the metal weight behind the speaker cone was the solution for BOTH of our units.
Big smiles all around :-)
Note - When you've opened the plastic shell and loosened the speaker from its mounting, the the big round metal piece/magnet sits within the actual speaker 'cage', slightly behind the speaker cone. It's tight but movable and can be pulled all the way back as far as it can go inside it's housing, away from the speaker cone.
Not sure why it gets pulled forward, but it isn't fixed in position and so could clearly get bumped by dropping the speaker or a reasonable impact of some sort. Once bumped forward it would severely limit cone movement and therefore volume.

Try swapping the connectors for front-left and front-right (just swap right at the back of the amp)

After the swap, does the front-left speaker work, and now the front-right is dead? If so, then it's a problem in the amp.
If not, then the problem is in the wiring and/or the front-left speaker itself.

Post back here with your findings, and we'll troubleshoot whichever part of the system is broken.

If swapping of left and right input sources and left and right speakers does not help...you might have a bad channel in your amp.

When I watch movies, most of the talking is directed to the center speaker. During surround sound, this gives a more realistic environment, with voices coming from the source (center where your tv is) and ambeint noise coming from the left/right corners.

Get a small center speaker to solve your problem.

fix your wires!

pls check the speaker cable that connect to the right one okay, plug it in output.

all of the channel are resonding to the test. but you cant notice it bec 5.1 speakers, each channel are designed to respond to a certain frequecies.  the L/R channel your talking about have the mid-range frequecies so it responds clearly compared to other channels...

 

hope that helps...
