I have a pair of LS70's. They sounds great except recently, I started hearing a slight (you have to listen for it) distortion in one of the woofers. I narrowed it down to the speaker, not one of the sources. It sounded a bit like inner groove distortion on a record. However, if you lightly tap the woofer, it goes away for a bit.
Has anyone experienced this? Is this a repair or is it easier to source a new (MW8100?) woofer?
