Obvious question...
How different is a "marine speaker" from non-marine? Huge and technically significant or mostly marketing hype? The key issue. Both can have polyprolylene cones, uv protection not sure but seems likely given the uv exposure in a typical car, plastic vs painted steel grill no big deal unless maybe you boat salt. Even then, a rusted steel grill may protect better than flimsy plastic.
Just curious.
I've used non-marine for awhile and w/low freeboard they do get wet. I'm talking watching water pools buzz off the cones when the bass kicks in. Not intended use for these speakers no doubt, but how much better are the marines w/uv protection their defining asset? And at what if any sacrifice to sound quality and selection? Do marine systems come in 10-12" subs?
Does anyone have hard facts or experience with this issue?
