CS21

The Clair Brothers CS21 is a sub low frequency loudspeaker designed to provide maximum sub bass reinforcement and low frequency augmentation in fixed installations. Its compact size makes it an ideal companion to 2 and 3 way full range installation loudspeakers such as CAT214, R2, R3 and R4 series. It is one of the most compact, 21" installation subwoofers available today.

CS21's unique features are a compact 30" cube design and symmetrical 4-port configuration to extend the low frequency response of the 21" woofer.

A high performance 21" woofer provides 100 dB SPL for a 1 Watt input measured at 1 meter, with usable in-room frequency response down to 32Hz. It's compact size enables the box to be placed in permanent applications without being obtrusive.

As with all Clair Brothers products, the CS218 is constructed of the finest Baltic birch plywood with a rugged epoxy finish to withstand the most demanding conditions.

The speaker grille is constructed of a durable 14 gauge steel which is powder coated and backed with a high grade articulated foam.
