Title: Speaker placement
Post by: tapeworm48 on October 31, 2006, 09:02:30 PM

Just received my new speakers (Paradigm Monitor 5s) in the mail today.  Quick question: I've got room for them on my media center table.  Only question is that the media center is where my plasma tv is sitting, so these would be sitting right next to the TV.  Are the speakers going to effect my tv?  Unshielded speakers can really mess up a CRT tv, but what about plasmas?

thanks.

I don't think so, but the vibration isn't good for the plasma, I'm sure.

If you place in a corner, remember that the distance from back wall and side wall should never be equal as it causes more pronounced standing wave cancellations. Closer to walls generally = more bass.
Rear-ported monitors should be given even more room to bloom and "breathe" from the back wall.
Monitors usually should be placed with tweeters at ear level.

Unshielded speakers will not have any effect on a plasma, LCD, SXRD, LCoS, or any other non CRT techonology. The reason that unshielded speakers have an effect on CRTs is that CRT set work by firing a beam of electrons at phosphers bound to a glass substrate. When the electrons hit the phosphers the enter a charged state and glow. Electrons, as we all learned in high school physics, havea negative charge. The magnets in an unshielded speaker are free to attract/repell the electron beam in the CRT thereby "bending" the ray. This excites the wrong pixels and messes up the picture. As no other TV light engines require thae electron beam to create pictures, the magnets in speakers have no effect.
