Axiom Home Page Forums General Discussion The Water Cooler Magnetic Shielding Problems

Hello there...

My m80s are causing interference on my tv ( red spots ), the speakers were 6 inches away from both sides. My TV is the Sony 40inchXbr, unfortunately the 'niche' in my family room limits my placement options. I did not have this problem with my old infinity speakers (200watts with built in sub). Does anybody here had the same problems? what are my options?

Thanks for your help

How long have you had the M80s? Regardless, I would call Axiom and get their advice. The magnetic shielding that is usually installed on the backs of the drivers may be loose or missing.

Hey...It's 4 months now, I did contact Joe and was asked to open and check for some lose 'cancelling magnets' and did not find one, unfortunately I noticed the problem after 2 months(cannot return anymore). Joe thinks that the problem maybe is the TV ( too sensitive for it's size and the fact that it's a direct tube). It's hard for me to believe that, but I'm a newbie to all this A/V stuff that's why i was hoping somebody could offer some answers here...

Thanks

I know I have my m60s sitting pretty much right next to my tv with no problems. It's an old 27" zenith (6 years old maybe?). The tv itself, long before I got the speakers, would occasionally have a spot show up with a slight greenish hue, that would last for a while and then go away for a month or more. That problem has persisted, but I know it's the tv. Is the tv old? It's possible that there is a problem with the tv.

M2is interfere with my 21" Sony display pretty badly if less than ~6" away, while for some reason the VP100 does not, even when sitting directly on top of it. (better shielding?)

I think that is the case also(poor shielding). My TV is pretty new (about 2+ years old) and my old infinity overture 2 which is right beside it prior to buying the m80s works fine. Is there something I can do? Can I put an extra shielding on the speaker myself or put something on the TV?

Thanks

Just wondering how do the 80's sound so close together.Mine are 8 feet apart.

My m80s are just 4+ feet apart and the TV in between. Niche space constraints limits my placing options. They still sound great though...If I could just pass this magnetic shielding problem, I'll be a happy camper...

Only the center channels are shielded for being right next to a TV. The M80s, with their huge motor assemblies, are only partially shielded and you probably need to get them a bit further away from the TV. I know in the past Sony TVs were very sensitive to this.

You could fix this by getting some thin (magnetic - not aluminum) sheet metal and putting it between the TV & the speakers. Try a 12" x 18" sheet. You can cover it in fabric to make it "decor friendly". (Think pillowcase)

To clarify (I thought it could be a little confusing),

The metal used as a magnetic shield does not need to be magnetized, just magnetically-permeable. In other words, use metal that magnets stick strongly to. Galvanized sheet metal is perfect for the job and can be found and cut to size at most hardware stores.

Hey...The galvanized steel shielding sounds good, If time permits, this is going to be my weekend project. I'll let you guys know how it goes...

Umm... ok... ??

You don't need to buy anything too thick. 16 or 18 gauge should work fine, and not be too heavy.

For the size, use a tape measure to see how high up you need to go to keep the sheet between the mids, woofers, and TV. The tweeters aren't causing your problem, so you don't need to go that high up. (RPTVs have all of the magnetically sensitive stuff in the bottom anyway). The drivers are in the front of the speakers, and probably go back 3 to 4" tops. 1 foot wide on the sheet metal should be more than sufficient.

One other thought, you might be able to open up the TV and put the metal on the inside of the set. No fuss, no muss. If the TV is wood, use very small, very short wood screws to attach the metal. Use epoxy if it is plastic.

Good luck,
