Soundmaster SMPro-4.08B 8-Inch Two-Way Coaxial Point Source Speaker

Full Product Description Designed in the U.S.A. for demanding live and installed audio environments, the Soundmaster SMPro-4.08B pairs an 8-inch low-frequency woofer with a large-format 44mm voice coil high-frequency driver in a coherent coaxial point source configuration. With an internal crossover set at 1.6KHz (12dB/Octave), it delivers seamless transition between lows and highs across an expansive 30Hz – 19KHz (±3dB) frequency spectrum.

Despite its compact 400mm × 300mm × 360mm footprint, the SMPro-4.08B achieves an impressive 125dB maximum SPL with 250W nominal, 400W continuous, and 1000W peak power at 8Ω. Integrated top and bottom recessed carry handles and dual rear SpeakON-style NL4 connectors make setup, rigging, and transport fast and convenient.
