Another cheap tweak to significantly reduce cabinet resonance is to apply DynaMat, or one of it's clones, to the inside to the cabinet. Dynamat, and similar products, are sold at auto parts stores for damping metal panels in cars to which speakers are attached. It is a simple, constrained-layer damping material that consists of a sticky, asphalt-like layer mated to a layer of aluminum. It is Very effective at damping vibrations and very simple to apply; simply peel-and-stick to the inside cabinet walls. Costs about $20. for two 8"x10" sheets. Fast, simple, effective, and relatively cheap. Then, if you're really ambitious you can internal bracing. But, you might need it by then
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.
