The MS10LB is one of the most powerful marine subwoofers on the market. What really makes this sub stand out is the sound quality and durability. It goes so loud that if you crank it up, boats that are thousands of feet away can feel the bass. The frequency range of these subs are so good that it will make all your songs sound so much better! These play frequencies that normal full range speakers cannot hit, adding depth and richness to all your music.

This subwoofer has a double-stacked 80 Oz magnet! They are twice as large as almost any other marine sub on the market, which is why these can handle so much power. In addition, the MS10LB has a fantastic sensitivity rating at 90dB, which means even if you have a smaller amplifier, the subwoofer is sensitive enough that it will still sound great.

The MS10LB was designed in a molded ABS plastic basket that is made with a special blend that is waterproof and un-breakable. You can literally jump on it and hit it with a sledgehammer without it breaking!
