My in ceiling speakers are angled. They are Yamaha and, because they are surrounds, they are not where I spent my money. That said, they have handled the surround duty beautifully. My fronts and center are matched speakers. I have always considered these speakers to be much more directionally oriented, which is why I have my speakers on the shelf. You might consider some sort of permeable cloth enclosure (grill cloth panel) to cover them up if you don't find a flush mounted solution.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.
