Video of MS12LB:


The MS12LB 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.

The MS12LB is 2,800 watts peak, 1,400 watts Program RMS and 700 watts CEA Rated! This sub is CEA-2031 compliant, which makes it easy to compare this subwoofer to other CEA compliant subs on the market. The issue in the marine audio world is that there are so many different brands with different standards on how they rate their products. We want to make it easy for you to compare our products to any brands on the market, therefore we provided all 3 ratings for you to do so.  The CEA compliant rating, which you should use to compare this to other premium brands that make CEA compliant products such as Kicker, Rockford Fosgate, Kenwood, Pioneer, etc. We also supply a program RMS rating that has become standard for many good brands in the industry such as Hifonics, Earthquake, etc. Lastly, we also supply a peak rating which almost all brands in the industry provide. This peak power is the amount of power the sub can handle for a short burst.

This subwoofer has a double-stacked 100 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 MS12LB 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 MS12LB 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!

Using only true marine grade components and materials, the Rockville MS12LB subwoofers are fully marinized against salt & fresh water conditions. These subs are completely waterproof and protected from the elements! They are UV treated and have a special waterproof coating to prevent water damage. These subwoofers also come with a 1 year warranty to give you the peace of mind you deserve when purchasing from Rockville!
