In doing a routine test on the 2075GS's systems, I found that there was no sound coming from the port bow speaker, and very little distorted audio coming from the starboard bow speaker. On the 2075GS, these are located in 'fishing lockers' on the port and starboard bow (I use them for the anchor, etc.) The OEM radio is an Alpine CDE-9852 AM/FM/CD player.
Anyhow, upon removing the port bow speaker, I found the mylar speaker cone had dried out and disintegrated. The speaker coil was still trying to drive the cone, but there was no cone there to move the air! Similarly, although not as bad, the starboard bow speaker cone had deteriorated and only half of it was left.
These didn't have much identification on them other than "MS650B" on the back. An internet search did not turn up much. I replaced them with a pair of Sony dual-cone, 4 ohm, 6.5" speakers and everything sounded fine again. In fact, probably better than the original OEM speakers provided by Bennigan.
At the end of the season, I'll probably be replacing the other two speakers in the helm and the "L" seat on the tri-toon, since they will most likely suffer the same fate. The speaker grill under the "L" seat already shows signs of cracking from UV exposure. I would have thought these would have lasted longer than this since we store the boat under the playpen cover from September through April.
The fix was not expensive (~$60) and did not take long to replace. Bennington, however, should have provided some service loops in the wires for speaker replacement. The leads were so tight to the OEM speakers that additional wire had to be spliced on to the speaker feedlines to be able to install the new speakers, even though the new speakers had identical push-on butt connectors. Not a very maintenance-friendly design by the boat manufacturer.
