Product Description
B-221 is a high-performance ultra-low frequency speaker specifically designed for ground stacking use, featuring a phase conducting enclosure design and two long stroke 21 "driver units. With extremely high sound pressure levels and extended frequency response, B-221 is an ideal choice for all large-scale sound reinforcement applications. When using three or any multiple of three B-221 ultra-low frequency speakers, they can be placed in a heart-shaped ultra-low frequency speaker array to achieve impressive directional control at lower frequencies, significantly reducing the energy radiated backwards.The front face of the speaker box is protected by a rigid metal mesh, which is supported by acoustic foam. The B-221 side panel contains 2 handles and is equipped with four rollers at the rear. The shell is equipped with two padding strips to protect the bottom plate from scratches. Each B-221 box is equipped with two concave structures with corresponding shapes to accommodate these pads and prevent the box from moving during stacking.
