    A number of the speakers I am looking at are unshielded and I wondered if there is a guidance for how far away from the TV they need to be to avoid problems.

    With my Ruark Prelude IIs, it's more like at least 30 inches!!!

    As for subwoofers, unless they're shielded they need to be a good distance away. My M&K sub really screws with my TV unless it's at least 4 feet away!!!

    If you own a rear pro TV you can be sneaky. The electronics affected by speakers are situated at the bottom of the TV so you can place speakers right next to the screen as long as the drivers are high enough (ie magnetic field can't reach the electronics). I successfully used my floorstanders right next to my rear pro TV for years like this.

    I would endorse the 30 inches guidance, my old Eltax LR6.5 left a permanant green stain on both sides of my TV picture, I had mine at 30CM:(

    1m (3 foot) is a safe bet. Though it depends on the speaker and how sensitive your TV is.

    Sorry to reopen this but is this still an issue with anything other than CRT models?

    only an issue with CRT TVs. if you have and LCD/Plasma etc. then there is no issue with unshielded speakers.

    As PSM1 points out, magnetic fields only effect the older large tube TVs. The electron beam in the TV-tube was aimed by magnetic fields; four plates for horizontal and vertical aiming. If a magnet was near by, the aim would be off. But modern flat screen are long past that method of producing a picture. I'm not aware of any problems with LCD or Plasma TVs and magnetic fields.

    I will say that I had a CRT TV and some large 12" speaker that were about 12" away, down and to the side, and didn't have any problems. Though with the same equipment, but a slightly different configuration, I did have some discoloration of the screen near the speaker. I simply shifted the speaker a bit and the problem went away. But again, that was CRT/Tube type TV. This is not a problem with modern TVs and Monitors.
