Seaworthy??
I have just received a pair of "Seaworthy" units for my 376. They had to be specially sent to the UK from Hunter's. The original grilles were destroyed by people's feet against the steering console. I am in process of making and fitting some 1" wide stainless strips 10" long to protect them - 2 per spkr.These are complete speakers all moulded in a brittle plastic material. The grille is glued on to the front and appears to be non-removable.Others having this problem might be better, quicker, and more cheaply served by removing the existing speakers, breaking away the thin plastic grilles and replacing them with perforated sheet aluminium or expamet. It is easy to dish and should be then be everlasting.
