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.
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!
