Can speaker cabinet vibrations be fixed?


Hi,

Recently I noticed that bass notes cause the cabinet/housing of one of my loudspeakers to vibrate, thus, distorting the sound of the notes. The vibration is at its worst when the speaker reproduces 50-80 hz test tones.

The cabinets for my speakers appear to be constructed of laminated particle board, the pieces of which were assembled using some sort of wood glue or possibly epoxy. The speakers measure 16"W x 28"H x 10"D.
Though the vibrations seem to be originating from the back piece of the speaker, I find that if I place my palms on the left and right hand sides of the speaker and then apply a little bit of pressure inward, the vibrations cease, and then the speaker operates normally once again.

These are not audiophile quality speakers, but if I can make a repair (I refoamed the woofers a couple of years ago), I'd really like to hang on to them.

If it's possible to fix this problem, any advice on how to do so would be very much appreciated. Thank you.

Concur with Stanwal.Use 2x2 material cut to size,make sure pieces are straight.Should be able to get a screw-gun inside to do the job.Determine screw length on a practice piece as all screwguns have a different torque.Don't glue until your happy,just drywall screws,then go back in after a week or so.Could be the beginning of a new hobby or dare I say it?A new line of employment.Nothing beats wood-working for satisfaction with the possible exception of teaching guitar,YMMV,Bob
