Jeepin ,,,,,,
one of the tests we perform on any new J&M speaker, is to put it thru a jig that we built in our R&D shop ,,,,, which sprays a steady spray of water directly on the front of the speaker cone, while it is playing at high volume ,,,,, for 48 straight hours, to make sure that there is no damage ,,,, same with the tweeter and midrange on the grill ,,,,,
the woofer cone is made of hard, injection molded polycarbonate, and the rolled edge is a form of neoprene ,,,,,, Mylar dust cover in the middle all sealed together ,,,,,
you can get the J&M speakers wet as often as you like from rain or carwash, it will not affect them ,,,,,
