Totem model 1: woofer rubber stiff -- Slight buzz


Hi everyone,

I have a totem model 1 that is more than 10 years old. I've noticed that on some tracks, there will be a slight buzzing sound coming from the woofer.
How do i know its the woofer?

Well if i press the woofer very lightly with my finger, the buzzing seems to go away.

--It only happens at certain frequencies
--Every thing else about the speaker is perfect
--I've brought the speaker to a repair shop, and the guy said its working perfectly, but that the rubber surrounding the woofer sometimes gets stiff with age, and this sort of thing can happen.

Is there anything I can do to fix this? My dealer wants USD500 to replace the drivers, but the repair guy was against this and said it wasnt worth it. However, he didnt give any other solution either!!

Appreciate any advice :)

Rubbing voice coil is your problem. They were probably over-driven. All you can do is re-cone (if there is a kit available) or replace the drivers. $500 for two drivers is cheap - so why not just replace them...
Another option is to rotate the woofer 180 degrees in the cabinet. Sometimes gravity will cause the cone to sag slightly, which in turn causes the voice coil to rub. Rotating the woofer so the gravity is now pulling on the cone in the opposite direction will sometimes (but not always) fix the problem.

Since it costs nothing other than a few minutes of your time, it is usually worth a try.
Sure its the coil? If the surround or the dust cover is not 100% bonded to the cone you can get a buzzing sound, usually on bass notes. Could be caused by dried out glue.
Contact Totem Acoustics, they provide excellent service and no one knows their speakers better.
