Bossman 21inches Double Sub

Sold by Acreage Enterprise · Accra Metropolitan

This is a Bossman BSX-221 dual-21-inch subwoofer. Model: BSX-221 LF drivers: 2 × 21-inch Power (Pro): 2,000 W Impedance: 4 Ω Sensitivity: 100 dB (1 W/1 m) Maximum SPL: 140 dB Frequency range: The plate appears to say 37 Hz–800 kHz, but that upper figure is almost certainly a printing/specification error; a dual-21 subwoofer would normally have a much lower upper operating limit. This is a very large, high-output subwoofer designed for serious PA systems. Two 21-inch drivers give it considerably more cone area than a single 18-inch sub, so it is intended to produce powerful low-frequency output for: Large churches Outdoor events Concerts DJs Live bands Large sound reinforcement systems
