Bose 131
Bose’s 131 Marine Speakers ($239) have a flush-mounted design for easy installation in precut boat-speaker openings, and their ported enclosures provide consistent, high-fidelity sound. They’re suited for temperatures ranging from -40 to 158 degrees, so they’ll keep the tunes pumping as the party heats up. Bose, (800) 999-2673; www.bose.com
