[RFI] RFI proof audio equipment recommendations

[Craig Thompson]

I need to buy my neighbors an amplified sub woofer, computer speakers and
wireless telephone system that don't pick up any RF. Do you have any
recommendations? This is less expensive for me to do this than any other
solution. I spent most of yesterday cleaning up their Radio Shack Sub Woofer
and then found out it only cost $100. What a waste of time!!

Is there a list somewhere of these devices?

Thanks for your help and 73, Craig
