5.25-Inch Two-Way Outdoor Loudspeaker with Sealed Weatherproof Enclosure, Aluminum Grille and Bracket, and Flexible Mounting for Patios, Decks, and Outdoor Audio Zones
The Russound 5B55MK2 is a 5.25-inch two-way outdoor speaker pair that delivers 90dB sensitivity and 72Hz to 20kHz frequency response from a sealed, weatherproof enclosure built for year-round outdoor use. The IMPP cone woofer and 1-inch Teteron dome tweeter produce clear, dynamic sound across patios, decks, poolsides, and outdoor entertainment areas, while 8-ohm impedance and 10 to 125 watt RMS power handling connect to standard multi-room amplifiers and outdoor audio systems.
The 5B55MK2 is part of the Russound OutBack outdoor speaker series and includes both an aluminum mounting bracket and a bookshelf foot for free-standing placement on shelves, tables, and ledges. The knurled aluminum bracket system mounts to flat surfaces, corners, and poles with U-bolts, accommodating any angle for targeted coverage. Gold-plated 12-gauge push terminals resist corrosion in humid and salt-air environments, and the aluminum grille protects the drivers against rain, UV, and debris.
Where the 5B55MK2 Fits
- Patios, decks, and outdoor dining areas where the sealed enclosure and aluminum grille handle rain, humidity, and temperature swings without degradation, the 90dB sensitivity fills open-air spaces with clear sound from moderate amplifier power, and the 72Hz to 20kHz frequency response provides full-range music without a separate subwoofer for background listening
- Pool areas, covered porches, and outdoor kitchens where the knurled aluminum bracket mounts to walls, eaves, and corner surfaces at any angle for targeted coverage, gold-plated terminals resist corrosion in humid and chlorinated environments, and the 5.25-inch form factor fits under overhangs and in tight mounting locations
- Commercial outdoor spaces and restaurant patios where the 10 to 125 watt RMS power handling scales from background music to event-level volume, pole mounting with U-bolts places sound above the crowd, and the included bookshelf foot provides temporary placement on shelves or ledges during seasonal setup
