Just mounted some Polk 650 speakers in the cockpit, next to the companionway, replacing the broken depth and speed instruments, and also purchased some plastic covers for the back, to cover the back of the speakers.
Anyone have any advice on anything I could add, inside the PVC covers, to improve / focus the sound outwards?
I hear conflicting advice. Needs to be sealed...needs air to drive sound.
