The Russound 5B55mk2-B is a 5.25-inch, two-way OutBack mk2 speaker designed to handle patios, decks, pool areas and porches through every season, while also working indoors in garages, workshops or on a shelf. An injection-molded polypropylene (IMPP) woofer is joined by a 1-inch Teteron tweeter for clear, detailed highs, all behind an aluminum grille that resists the elements.
Russound rates the 5B55mk2-B at 72 Hz - 20 kHz (+/-3 dB) with 90 dB SPL (2.83 V @ 1 m) sensitivity and a recommended amplifier range of 10 - 125 W RMS, giving compact sound for smaller outdoor spaces and covered areas. Each cabinet measures 11.25" x 7.5" x 7.5" (28.57 x 19.05 x 19.05 cm) and weighs 5.4 lb (2.4 kg).
Installation is flexible. The heavy-duty aluminum bracket mounts to a flat wall or tucks into a corner, and it accepts U-bolts for pole mounting (U-bolts not listed as included). For indoor or temporary use, the included bookshelf foot lets the speaker stand on a shelf or tabletop. Connections are made with 12-gauge terminals that resist corrosion.
