First, let me introduce myself. I'm Jordan, a student at UT Austin, with a nasty stereo habit. I've just bought a nice pair of Polk Monitor 10a's, to satisfy my need for something with more balls than my current Genesis Physics bookshelf speakers. I figured the Polks would be a fine choice, since my father has long had a pair of Monitor 5jr+'s that I have always loved.
Anyway, I've been doing a little research and have noted that the mid-woofers from this era have issues with the magnets coming unglued. I intend to eventually implement the J-B Weld fix detailed in several threads on this forum, but I'm supposed to pick the Monitor 10's up tomorrow and drive them 150 miles from Houston to my apartment in Austin. While I know that all drivers are currently good, I'm concerned about the risk of one letting go in transit. From your experience, do these woofers mainly get damaged in shipping or from falls, or is minor jostling enough to do the trick?
Also, should my father be concerned about shifted magnets on his 5jr's? He bought them in 1991 and hasn't had any problems since (he says they're the best $300 he's ever spent), but they've had a fairly sheltered existence.
