Product description

The B1 is the principal subwoofer used with the F1222 loudspeaker. Its internally braced bass-reflex cabinet houses two 15” drivers and produces a round, dry, rather deep, natural bass. The B1 cabinet is constructed from marine plywood, which incorporates the handles, has an impact resistant paint finish and MAN CF4 stud plate rigging points. There are fittings at the top and bottom for securing an optional wooden lid, and mounted on the rear are four heavy duty wheels.
