What a pain in the ass...

Got my 15.3 from funkywaves today. OMG not only is the craftsmenship over and above anything I've ever seen but the added bonus of solid hard and accurate bass is unbelievable..

However because of 95% of my electronics being on my main floor this is causing my alienwarecomputer and hdtv sat box to run interference (ground loop) causing the unbareable hum. I believe I can solve the problem with filters. I am going to attempt that tomorrow hope all goes well. If anyone has suggestions feel free.
