Is there any risk to store for a long period of time 2 speakers face to face when repulsive magnetic force strength due to magnet leaks is perceived (regarding ferrite-ferrite, ferrite-alnico and alnico-alnico even if magnet leaks are lower ...) ?

Same issue for 2 speaker pairs in separate box but magnet against one another.

Same issue when speakers are in 2 separate boxes stacked on top of one another, or one side by side.

.
Are there some recommendations ? Thanks for :)

- It's a valid question , but ;

- I would only trust a definative answer that has originated from inside JBL ( or has come from an expert on magnetics ) / everythng else would be just conjecture based on someones' notions of "best practice" , etc. , etc. or suppliers' storage conventions ...

- If you're this concerned about inducing permanent magnetic anamolies due to , " too close storage" / then stow your drivers' separated from each other, until further info is made available .

Well have you ever heard of an issue with coax drivers using a compression driver that get's threaded in??? I have not and that gets a lot closer magnet to magnet. You also have to remember the bucking magnets used for Video sheilding. Just my opinion but I wouldn't loose sleep over it.

@Earl K : please let us know http://planetsmilies.net/not-tagged-smiley-1987.gif (http://planetsmilies.net)if you have any further information from inside JBL or other

@Robh3606 : nice pictures (E145 ...http://planetsmilies.net/happy-smiley-900.gif (http://planetsmilies.net)) Coax driver seems to be a good example http://planetsmilies.net/not-tagged-smiley-2801.gif (http://planetsmilies.net)
