Strange sound in one of my Creature speakers

The pre-amp is defective. Get them replaced.

Go onto the internet to see if any one has crossovers for them, Evan check out ebay.

it might b ethe wireing of the speakers

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.

I had the same issue and applied ezimme solution from Jan 04, 2009 and it worked perfectly. Thanks ezimme!

Click on the speaker on the bottom left toolbar and ensure everything is all the way up

I had the same problem. Then I read about the volume controls on the right speaker. They are silver buttons for me on the front bottom left and right of the speaker. Now they play really loud!

check on the speaker software were you can set master volumeetc. check for balance volume .

I had a problem with the speakers not working properly. The green lights lit, but the amount of sound coming from the speakers compared to that of the sub was much lower.
I decided to take it the speakers apart.
I found that the magnets on the speakers had moved forward slightly in the plastic cage they sat in. I pushed them back as far as they would go, and Hey Presto! working again!
I hope this helps someone!
