The ES-221 is a twin 21′′ subwoofer system designed to provide high levels of low frequency energy. The loudspeakers, equipped with 6′′ voice coils, highly effective heat dissipation schemes, and an extremely robust mechanical design are ideal for dance club applications where long hours of demanding use are the norm.
The reinforced enclosure design and crossfire configuration are key in providing stunning, high-intensity bass.
The cabinet is designed using top grade birch plywood and protected with an impact resistant ISO-flex paint. The front elements of the cabinet are protected using a solid metal grill assisted by an acoustically transparent fabric.
