Would a standard 120v light dimmer switch control the volume on a speaker?

I'm looking for an easy way to quiet an in-wall speaker without turning down the whole system.

I am having two speakers mounted in the wall on each side of my headboard. I want to be able to turn them down (or up) separately from the TV they'll be hooked to. My wife wants a speaker mounted next to my head so I can watch TV and she can sleep without hearing it as much!!! I am hard of hearing and tend to have the TV too loud for her!!!

Interesting question! I'm not an electrician, and I've never attempted doing what you suggest...but offhand I'd be hesitant to try it. I hope a more knowledgable person writes in. But in the meantime....

I'd be afraid of changing the impedance--and both speakers and amplifiers are 'matched' in that regard. Also, stereo volume controls are actually part of a "pre-amp"; they modify the "input" signal--they're not dealing with the amplified result.

I don't know if I can mention specific store names here, but if you've got questions, they've got answers. Go there & tell them what you want to do. They'll sell you the right part.

Electronic light dimmer will NOT work to control a speaker. It will cause distortion if it does anything.

Thanks Guys,

I was at one home electronics store and they tried to sell me a $50 volume control knob. That's when I started getting "creative" with my thinking thought of the dimmer switch. I then went to a local electronics shop and they sold me a basic 10 watt LPAD. I'll mount it in a gang box and put a cover plate over it, should do the trick, $3.50.

Thanks
