How can I tell if my ancient speakers are "shielded"?

How can I tell if my ancient speakers are "shielded"?

I have a pair of floor speakers I'm using as the front speakers in a 5.1 setup with my new Panny 53WX42, and I'm not sure if they're video shielded, hoping someone can point me to the way to figure out whether they're okay set up fairly close to the tv set. I bought them late 80s/early 90's at JCPenney, was told they were made by Technics. They're 3-way, have approx 10" flat "honeycomb" woofers. I can't find anything on them through Google. Thanks for any help finding info on the speakers and/or properly setting up the HT.

I would guess that they are not.

You will be able to tell if your TV screen starts to display any sort of color bloom on the edge of the screen closest to the speaker. If that happens they need to be moved away quickly as damage can occur to the screen.

If image distortion does occur--do not move the speakers away quickly as advised above; rather, move them away very slowly. Otherwise you risk inflicting permanent damage to the TV.

Curious?

Why would that be since the damage is being cause by the magnetic field.

It should be safe by just moving it away. No problem.

Thanks for all the input, y'all -- even though I couldn't detect any problems with the TV picture, I moved the speakers further away just to be safe; they're each now about 4 feet from the TV. Thanks again for the responses.
