How to use

Place the BX-1550 on a stable surface or use the flange to mount a compatible top speaker. Connect the passive crossover and wiring according to your PA system layout, ensuring appropriate amplifier power and correct polarity. Position the cabinet to allow unobstructed bass ports for optimal low-frequency output. For transport, use the bar handles and ensure corners and grille are protected.

Recommendations

Use an amplifier and speakers matched to the BX-1550's passive configuration and rated power. Allow clearance around the bass-reflex ports, avoid placing the subwoofer directly against absorbent materials, and secure the unit during transport to prevent damage to the grille and corners.
