M1 Pivot Mount brackets are designed to allow maximum mounting versatility for Poly-Planar® box speakers (MA9060, MA800, MA7500 and MA1610) and other popular name box speakers. Since all speakers are directional, M1 brackets allow you to point your speakers in whatever direction produces the best sound quality for the location, whether you’re in a small cabin or on the upper deck of a luxury yacht. The brackets also perform exceptionally well when mounted in marinas, restaurants or backyards.

The MCD-6 CD Changer holds six of your favorite CDs for your uninterrupted listening pleasure. And with the shock resistant CD mechanism you can still hear your favorite music even while crashing the big ones.
