Take great sound with you when you play on the water. Infinity 6902m marine speakers are made from 100% weather-resistant materials they'll stay shipshape through years of nautical adventures!
The 6902m's polypropylene 6"x9" woofer cone is bonded to a tough, UV-resistant rubber surround. It'll kick out a broadside of bass, while maintaining excellent sunlight and moisture resistance. The corrosion-proof, cast-polymer basket is impervious to deterioration caused by salt, moisture, and UV rays. The stylish white non-removable grille is specially treated to resist yellowing.
For excellent projection of the highs, the 1" semi-dome polypropylene tweeter is mounted to the grille. Infinity seals the front of the woofer cone along with the speaker's magnet structure for extra protection against moisture. Stainless steel mounting hardware is included.

Infinity 6902M Reviews
Average Customer Review:
Can't beat them for the money
I have installed these in two friend's boats who were both extremely
pleased with their sound. Aesthetically, they look fantastic, and seem to
be built very well. The highs just sound amazing and very clear. They
have surprising bass for their size, but you may still want to add a
subwoofer for a little extra punch.
Another friend was looking for outdoor speakers to build into the sides of
his built-in BBQ/bar and since he didn't not want the typical outdoor
speaker (he wanted flush, like an in-wall), I suggested these. However I
did make sure that he wired them in series since these are your typical 4-
ohm car speakers and would not be compatible with most home receivers.
Since he wanted four speakers, that worked perfectly,
as he would have the proper 2-channel, stereo sound. Once again,
another person was very pleased with the choice and I was the hero a
third time, even though the choice was a no-brainer for me.
All in all, I believe you would be hard pressed to find a better marine
speaker for the money. It's just hard to go wrong with these Infinity's.
Crutchfield Customer Review (What's this?)
These are excellent speakers. Very articulate. Great highs and bass (why I decided to with 6x9 instead of ye olde 6.5"). Just installed these in the cockpit of a J35 sailboat along with a Clarion CMD4a w/ ipod control and couldn't be happier. I've listened to many different speakers in my life and these Infinitys definitely live up to the name.
