EMF and Speaker Magnets?
Okay, so I have this fairly cheesy EMF detector on my smartphone, no idea if it's accurate or BS.

While trying to find the cause of some recent oddness at home, I used it to sweep the house, focusing on my wifi items & computers, tv, other cellphones, etc to see if there was a spike. There really wasn't.

However, I noticed a near complete dead spot about 2ft in front of my speakers, which were off at the time. It dropped to about 5% of the baseline average I got everywhere else. Of course, if I got right up to the speakers, the thing went off the chart, about 3-400% higher than baseline.

I have a lot of speakers, but only one design really exhibited this, they're triangular & have drivers on 2 of the 3 sides.

Am I getting shielded in front of my speakers by some type of magnetic void 2ft out from the magnets?

Maybe it saturated the EMS detector?

I dunno about that - I tried putting it waaay nearer to another speaker magnet I had disassembled & the thing jumped thousands of times higher.

I'm beginning to suspect it has to with the 60 degree orientation of the two drivers in this design, but that's just a guess.

However, I kind of debunk myself, too, as the void occurs in front of each single driver, not at the middle point between them.

Stumped!

Get a few extra pairs, and place them around you as you sleep.

Re: EMF and Speaker Magnets?
how in the hell do you expect to use something (cell phone) which is already emitting an EMF to then detect other EMFs?

this sounds like it wouldn't work from the get go...

A bucking magnet or mu metal shield is sometimes placed on the speaker driver to protect nearby video screens from being fucked up by the magnetic field. It might extend in front of the speaker, I don't know.

When I was younger and stupider, I had a bunch of 15" speakers with 100oz magnets, so I decided to line my box springs with them in boxes with my mattress on top of that. After a few days I realized that the headache I had was probably caused by sleeping in the magnetic fields.

Good idea, I do have 2 pairs. Might make for a hell of an alarm clock!

 Quoting: John Everytard


Agreed, unless it's accounting for the device's output. I have no idea if the milligauss reading are correct at all (in fact the baseline I referred to was about 400 which seems crazy high & makes me agree with you), but it does behave as expected around known EMF sources, so I kinda trust it in a relative fashion. That's why I wanted to stick to percentages.

Wow, haha! What were you looking to achieve? A little thump in the hay?

I'll nix that idea off the list then!

Nice thought. All of my speakers are the same brand, but these are the oldest, from the late 70's. I haven't seen any secondary magnets on the drivers in question, but aside from re-foaming them, I have not been inside the spider or any other driver components.
