Silly question... is magnetic shielding really needed if I have an LCD monitor? The reason I ask... I have an all Quad dynamic speaker setup for my home theater system-to-be, and I would like to run an active Quad speaker for the center channel, probably the 12L Active. Of course that speaker is not magnetically shielded. Does this matter if I have an LCD screen? Will a magnetic field affect it's performance?
I already have a Quad L Center that I could use that is magnetically shielded, but I don't have a spare amp channel for it and I'd rather have all identical speakers anyhow.
Thanks in advance!

No problem. You only need shielding if you are using a CRT (Tube type) TV.
that CRT screens use a magnetic 'gate' to aim the electron beam. Magnetic fields from speaker drivers can interfere with the gate field and put that results in the beam getting sent to a point on the screen where it isn't intended to go, resulting in picture distortion.
LCDs and plasmas have each pixel controlled separately so there's nothing to aim and you don't get problems with unshielded speakers because of that. It's only a problem with CRT screens.
