At February’s Miami International Boat Show, JL Audio unveiled the M6 coaxial speakers (part of a larger series that includes subwoofer drivers and enclosed speaker systems). JL designed M6 speakers to reproduce low-distortion bass and evenly disperse smooth sound in open-air boat environments. The speakers come with classic (all white) or sport (gloss white or dual-metallic finish) grills, and LED illumination is an option. Offered in three sizes — 6.5, 7.7 and 8.8 inches — speaker pairs cost $429.99 to $649.99.
