LOLYou could lose your filling when adjusting the volume.
For near field pressure, I am leaning toward No. On the other hand, EMI might be a problem if too close. Due to strong Magnetic Field, created by a powerful Magnet use on a sub. When doing DIY, my dual woofer on my sub. Use as a TV stand, did affect the picture on my CRT TV that I was using way back then in the 90's.Does anyone think there would be issues placing a Rythmik within inches of amplifiers and source electronics? I'm thinking of near-field pressure and also possible EMI.
While a 3/16 sheet of metal between the sub and your electronics , would stop those EMI. It is not something that would be eye candy, if place in between your sub and Audio rack. And pretty sure this option is a write off, since it was just for info.
