Question for the home theater geeks

[mascan42]

Is there a difference between "magnetically-sheilded" speakers and "video shielded"? Because my new "video shielded" speakers are still causing yellow and purple blooms on the sides of my TV.

I've never heard the phrase "video shielded" before. The appropriate phrase for speakers that won't screw up a TV picture if they are located too close is "magnetically shielded".

My guess is that the speaker manufacturer's marketing company is playing games by saying something that makes people think one thing, but really means nothing. It's kind of like when DirecTV changes the phrase "DVD quality" to "digital quality".

its two different phrases that mean the same thing. What kind of speakers are you using?

He's right...& what are the speakers?

[Mobo]

A thin layer of aluminum foil will block any magnatism coming from the speakers. That's what causing the discoloration.

I thought this sheilding was virtually ubiquitous in "home theater" front and center channel speakers. But really, if you're running an LCD or a DLP or Plasma do you really need it?

A standard speaker sends its magenetic field out the sides of the speakers, which is why it screws up your TV if you put it too close.

A magnetically shielded speaker sends its magnetic field front to back, so you can put it near the TV.

You can make any speaker magnetically shielded.

1. Purchase "bucking magnets" for your speaker drivers. Open your speakers.

2. Turn the bucking magnet so that the speaker magnet and bucking magnet repel each other.

3. While oriented this way, force the two magnets together, and hot-glue them together, and secure them with duct tape.

Now the speaker is magnetically shielded.

Did you get them from a guy in a van that just happened to have extra speakers left over from the warehouse?

hmmm never tried that...

Your post is correct, cogent, and informative. However upon reading it, I can't help but picture your latest contribution to the post your pics thread. :icon_eek:

Why not just move the speakers away from the TV?

[mascan42]

The speakers are by RTR. I'd move them away, but I'm in a small apartment, so there's not enough room. Maybe there's some sort of leakage in the shielding . . . I might have to open them up and see if there's a problem.

I know. What was I thinking, singing in front of people like that?

Seriously, that speaker trick works, We used to do it when I was installing home theatres years ago.
