Had not heard of Genelec so looked them up:
http://mixguides.com/studiomonitors/newproducts/audio-genelec-new-monitors/

One would think that one could find an RFI-safe 
speaker/system for less than $1,000-$6,000!  Ouch!

> Much of the RF comes in on speaker wiring. The rest of it is due

> filtering of the signal wiring. I've seen a LOT loudspeakers with 
> built-in power amps. I've only seen one (a Genelec) that didn't 
> have serious RFI problems.
