I have a Mission bookshelf speaker that buzzes loudly when playing bass notes. I don't think it's the speaker cone because when I press my hand against the back of the speaker enclosure, the buzzing stops. The back is vibrating. There are no screws on the back, so I'm not sure how to take it apart without prying it out and possibly making the problem worse.

 

If anyone has any knowledge on how to fix this, I'd appreciate it. I've had the speaker for a long time and I love it. I'd rather fix it than replace it.

That indicates either the back isn't braced or if it is the bracing has come loose. To fix it you need to remove the drivers and work through the driver holes.
It also could indicate that you're trying to get bass from it that it was never intended to give. There comes a point where a sub is no longer a luxury that you can't afford.

Thanks. I actually have a subwoofer and a receiver with the crossover set at 80 Mhz. (Sorry if I'm butchering the lingo).

 

I think I did knock the bracing loose years ago by playing the bass too loud on an old system. In the past, I somewhat compensated for it by placing the speaker directly against a wall, which helped control the buzzing. However, if my new configuration, that's not possible.

 

How do I fix the bracing? With glue or something else?

Glue, if it's not totally broken. Gorilla Glue works well, as it will expand to fill a gap between the brace and the back.

Thanks, Bill. I'll try that.
