I have an entire Infinity Overture 3 surround sound system I'm hoping to sell, but am having an issue with one of the floor speakers and perhaps someone here can shed light on the problem as I want to be honest when listing the speakers for sale.

I must admit I'm no audiophile so that's why I'm here seeking advice from those of you who are.

So one of the speakers doesn't work well at levels below -45 db. Anything higher than that and the speaker will kick on and usually stay on, but below that level it has a tendency to go in and out. Sometimes I'll crank it to about -20 db and then back down again so it stays on.

I'm not sure what could be causing this. I've already tried switching out the audio cable and that didn't seem to work. I'm pretty sure it's something with the speaker and not with the receiver but of course I could be wrong.

Anyone have this problem before?

Thanks in advance for your help.
