Polk/MOMO Speakers
 

Polk/MOMO Speakers: Anybody have to replace any of these? What with? My 2007 Sea Ray 230 Fission ski boat has had 4 of the 6 drivers fail because the glue holding the magnets crystalized and the magnets shifted and came loose rubbing the voice coils and causing gritty sound. The speakers did not blow.

I haven't replaced Polk Momo. I've only ever run their subs and they held up well.

For durability, it's hard to beat DC Gold speakers. They're a bit pricey but they're waterproof and hold up to the elements better than any other marine speakers I've ever used. They're among the best sounding as well.

They lasted 10 yrs in the salty marine environment-sounds like they did pretty good
