Poly-Planar SB-50 2" 35 Watt Spa Oval Speaker - Grey

The Poly-Planar SB-50 2" 35 Watt Spa Oval Speaker in grey delivers full-spectrum audio performance in an exceptionally compact form factor—ideal for marine, spa, and outdoor applications where space constraints demand efficient sound reproduction. Designed for professionals and facility managers who require reliable audio without sacrificing clarity, this speaker bridges the gap between portable convenience and high-fidelity output. Whether integrated into existing multi-zone audio systems or deployed as a standalone reinforcement unit, the SB-50 meets the acoustic demands of wet environments and vibration-prone installations.

Built with chemical-resistant components, the SB-50 withstands prolonged exposure to chlorine, saltwater, and spa treatment compounds—critical for any audio equipment deployed in corrosive aquatic environments. The 35-watt power rating and full-frequency audio range ensure balanced treble and bass response across the audible spectrum, eliminating the tinny distortion common to undersized speakers. The oval 2-inch driver configuration optimizes acoustic projection while minimizing installation footprint, making it suitable for tight mounting locations where traditional round speakers prove impractical. Weighing just 0.65 lbs and measuring 4 x 3 x 6 inches, the unit integrates seamlessly into retrofit and new-build audio systems alike.

Facility managers, pool and spa operators, and marine vessel owners benefit most from the SB-50's rugged construction and weatherproof reliability. Installation is straightforward for electricians and AV technicians familiar with standard in-wall or surface-mount speaker placement. The grey finish coordinates with contemporary facility aesthetics while the compact oval design fits discrete locations—overhead soffits, alcoves, or engine compartments—where standard speakers cannot. For multi-zone audio systems, the 35-watt specification ensures adequate sound pressure levels in medium-sized spaces, and the full-frequency response prevents audio degradation across distributed speaker networks.
