Danger to LCD from Main Speakers Vibration?

Jitter

Are they shielded?

The speakers are mid 70s vintage (L-65s) so I doubt they're shielded. I'd be placing them 18" - 20" away from the LCD screen to either side...

LCD TV/Monitors are not affected by unshielded devices. Only CRT's are subject to problems caused by magnets.

goto monoprice dot com and buy a wall mount for $30 and mount the LCD on the wall.

If you are really concerned get some Aurio ProMax or Aurio Pro bearings and float the speakers on the stand. Expensive but it works and the sound will clean up on your speakers. Or a cheap method would be some herbies feet or something that has a money back option.

I doubt it would cause that much of a problem otherwise if you can not wall mount the TV then you need at lease some t type of isolation under the TV like a Ginko platform or some other DIY solution for isolation. The biggest problem will come with vibration being introduced to your DVD/CD player and degrading the sound.
