Overview |
|
Designed and styled specifically for use
in the marine environment, The MM651UM isn't just car speaker labeled
for use on a boat. Used in a speaker can or installed on your boat, it
works great for both! A unique tweeter-on-grille design eliminates the
traditional tweeter post, resulting in a totally sealed front. With
waterproof materials, it will stand up to just about any harsh marine
environment while sounding great, thanks to Polk marine certification
and Polk technology. |

Features |

prevents water intrusion.

mount which eliminates the traditional tweeter "stalk".

into back of magnet means there's no need to find room to hide an
extra box.

terminals and mounting hardware will not corrode or tarnish.

of salt fog and UV testing (ASTM international B117-03 standard
practice for operating salt spray (fog) apparatus and D4329-99
standard.

- Neodymium is a rare earth material
we use in all MM driver magnets, excluding 461P, that are about 1/10
the weight of a comparable ceramic magnet and much more powerful.
- Carbon composite basket based on
the spokes of a wheel is lightweight and will not flex.
- Woven glass composite cones
feature tremendous stiffness-to mass ratio. Lower mass means faster
transients and finer detail.

the best possible performance, even at extreme listening levels.

speakers are built tough to withstand the toughest environments so
they are perfect for use in boats of all types. That's why Correct
