I have a pair of West Mountain Radio COMspkrs that are interference-free. Took awhile to get 'em, as they were on back order for "too long". The side of the unit with the amplifier is literally touching the side of a THP KW amplifier and the other speaker is about 12" from my open wire feeders. FWIW, your MMV ... 73!
