Less than a good investment
.. from the archives:While it is true that some more modern speakers have improved in longevity, I've never been satisfied with how well they hold up in cold, heat, sun, salt, constant moisture and wind pressure. Being both a musician and a sailor I will attest that everything acting on an cockpit speaker constitutes the perfect recipe for rapid speaker-cone failure.We solved this issue at Cherubini after my brother built a pair of speaker boxes for our Raider 33. They each housed a 6x9 car speaker, surface-loaded as to facilitate replacement. The boxes were made of 1/2" white-overlay plywood and fitted with square rubber feet at the corners and plain Herreshoff yacht cleats on the top which functioned as handles as well as where to wrap up the cord. RCA phono jacks were fitted inside the cockpit-seat lockers so that the connecting cables could be led out through the lift handles/ hatch scuppers. When needed, the boxes were dug out of the lockers, hooked up, and stood on the cabintop, cockpit seat, wherever. With metal aluminium grilles they took an incredible beating in the locker and getting kicked around the deck. They were cheap and easy to build, repair, or replace-- certainly WAY cheaper than the incredible prices some makers charge for what they call 'seaworthy' speakers-- parts only, exclusive of cutting holes in your fibreglass deck.Think about it.JC 2
