Right now I have a small sub, 8", 50w(yes they come that small) and it's under my CRT TV. the top of the sub is about 2 ft from the bottom of the TV. The TV is on a metal table, so there is a sheet of metal between the TV and the sub. There are no interference problems right now.

I'm looking to upgrade to a bigger sub( bic h100, eD a2-250) and I'm concerned that a bigger sub might have too much emf and could ruin my TV.

aside from moving the sub, is there anything I can do to block the emf?
Anything I can put between the sub and the TV?
Any way to shield the sub itself?

Thanks,

Jason

JasonAFAIK, the only effective means are distance and MuMetal. The latter is much more expensive.

Making your own bucking magnet would help too.

Couldn't be done though in an A2-250 because of distance to the port.

There may be other issues besides gaussing the CRT. If you get the bigger sub, the boundary of the underside of the metal table (and its undersides) will be even closer than 2 feet. There have been many posts here about why it's generally not best to have a sub that close to reflective boundar(ies). I don't mean ventilation for the sub's plate amp.
