What's that buzz, tell me what's a happening...

Playing Radio Head's "Pyramid Song" (a little loud but not even 10 watts) where Thom Yorke's eerie hum begins and one of my speakers starts to make a vibrating sound like a cheap old phonograph! I figure its inside the box, maybe behind the woofer. Almost sounds like a screw is loose and matching frequencies are causing it to vibrate and sing. This has never happened before!

"S**t" says I, and I start putting pressure on every screw head, binding post, sides of the cabinet etc to no avail. "S**t" says I again. I want to rip apart the woofer, get in there and hot glue everything. Probably not a good idea.

Ya think I can take the screws off the woofer or the binding post plastic housing thingee (or both) to take a peek? Is this a typical DIY thing to do? We're talking Totem Sttafs. What do you think could be loose in there? Or is it something more ominous...:-(

Call or Email Totem...they'd be the best to tell you whether you should and can open things up.

If you are handy with tools taking the woofer out shouldn't be a problem. Hopefully it's as simple as a wire slightly out of place and is vibrating against something. Knowing exactly where it's supposed to be is difficult.
Be sure to note the correct orientation of the driver before removal.

Perhaps you are simply over driving it...this is after all a small woofer and low frequencies take huge amounts of excursion on a small woofer?

It may also be a lose dust cap or perhaps the driver wire is touching the woofer cone when driven hard.....so yes do open it up and take a look!

First, try tigthtening all the woofer screws a little to see if one is loose. This happened regularly on my Spica Angeluses, exactly as you describe. Important: Don't overtighten! If the screw doesn't turn easily, then it's probably not the problem. If you get to one screw that turns easily, turn it until it's snug, then play the troublesome track.
