Magnets for removable baffle

[nonsuchpro]

Hey all,

Do you guys have any recommendations for strong magnets to use on a removable baffle? I see some other speakers that use em... I'd like to do the same kinda thing. Basically, what strength would I need and wheres a good place to get em.
Thanks!

Ebay is a fine place to buy them. If you arn't in a hurry I may have a few I can let you have but I have misplaced them. Now having said that it realy might be about as good to try using velcro but that doesn't sound hi teck in a speaker add.

buy something bigger than 3mm that's the size I used and they are just adequate for a light grill, give it a light bump and it falls off. that size only works if it is magnet to magnet. any cloth in between and they won't hold at all. I think 10mm would probably be advisable.

If you want them exposed you can get some nice gold plated ones.

"D72" disc, 7/16" X 1/8" is what I use.

Chosen to fit a 1/2" forstner bit hole.

My mount is a combination of mechanical and magnetic. The grill frame has a "ledge" to rest upon at the bottom. Be careful to get the polarities aligned...

Thanks all! I guess "pull force" is how I would gauge it. Seems like if you use "case 2" you'll get the best results.

Do you mean grills? Magnets are not suitable for attaching a baffle.

We get the magnets for our grills from Lee Valley.

And what Tony says... some of our heavier grills need more than 4 magnets, early attempts have grills that will fall off if you look at them wrong. I fear someday the grills themselves will damage the speaker.

I mean baffles. Im pretty sure I've seen them used but cant remember where. You have to use strong magnets for sure.

Any magnets strong enuff to hold a baffle on and keep it sealed will have to have special provisons (and tools) to be able to remove it. Some sort of electromagnet or a lever system that won't damage the enclosure.

Your baffles have to come out often enough to use a system like that???

HArdware stores and home centers like Home Depot ought to have magnetic cabinet latches, like they use on cabinet doors in your kitchen.
