A21s Sub Bass

Passive single 21" subwoofer, 1200W

Overview:

"The A21s is a single 21” bass reflex sub bass loudspeaker. Designed for use in nightclubs, mobile DJ events, live events, houses of worship, auditoriums etc. It employs a high power long excursion 21” driver capable of delivering exceptional high levels of bass and sub bass frequencies. The A21s sub bass loudspeaker is compact, tonally accurate and can be used in singles, pairs, stacked or flown using respective accessories. By virtue of its size and geometry it tends to radiate more energy forward than behind thus steering sound where it is needed. Stacks of the same can bring unprecedented amounts of energy to the fore. Recommended configurations are 1 or 2 subs for every A112, A115 or the A215 midtop. Using extended dsp algorithms this sub can be configured as cardiod pattern, bringing new level of control in live venues"
