The AC22 is a single 12" subwoofer module that is designed to provide an affordable solution for small-scale sound reinforcement of the LF band. The AC22 offers high quality bass output in a compact, durable enclosure, which can be easily integrated within the decor or construction of most installations. The AC22 is a dedicated LF / subwoofer system in a rectangular, computer optimized enclosure. Loudspeaker complement consists of a single 12” LF woofer loaded into a ported sub-enclosure. The entire enclosure is constructed of durable 12-ply void-free birch laminate, dadoed for strength and durability. McCauley’s rugged ProCoat elastomeric finish provides excellent weather protection and will resist scratches and scuffs. Binding posts are located on a recessed steel jackpanel on the back side of the enclosure. Perforated steel is employed for frontal protection of the loudspeaker complement.
