JBL MS 9200 Speaker - 100 W RMS - 2-way - 2 Pack - 37 Hz to 20 kHz - 4 Ohm - 7.69 x 10.81

With waterproof motor structures, a one-piece cast-polymer basket, a sealed magnet, rubber surrounds and a grille-mounted tweeter, the JBL MS9200 holds up to the sun, the sea spray, all that salt and all those washdowns. Conditions out there are brutal - and the roar of Mother Nature makes extraordinary demands on your speakers - but the JBL MS9200 is up to it.
