The Rockville MS10LB RZR is a 10-inch marine subwoofer built for boats, UTVs and other open-air vehicles. Rockville pitches it as one of the loudest marine subs you can buy, with a rugged build meant to shrug off sun and spray. It suits riders who want heavy bass outdoors and don't mind feeding it real amplifier power. Against name-brand marine subs it trades brand prestige and refined sound for raw output and a tough enclosure-ready design.

Owners describe the MS10LB as very loud for the money and tough enough for boat duty. Some say it needs real power and a proper enclosure to sound its best.
The Rockville MS10LB RZR is a 10-inch marine free air subwoofer with LED lighting, in black. It is a free air design, so it does not need an enclosure. It plays low frequencies that standard full-range speakers cannot reach.
The basket is molded ABS plastic that is waterproof and built not to break or bend. The cone is polypropylene with a rubber edge. The sub uses marine grade components, is UV treated, and has a waterproof coating against salt and fresh water. The motor has a double-stacked 80 oz magnet and a 2.0" 4-layer dual voice coil.
Power is rated three ways: 2,400 watts peak, 1,200 watts program RMS and 600 watts CEA rated. It is CEA-2031 compliant. Sensitivity is 90 dB, so it can be driven by a smaller amplifier. It comes with a 1-year warranty.
