The A112 is a single 12″ mid-top loudspeaker mated to a 1″ compression driver which in turn is coupled to an 80° x 60° non-rotatable constant directivity flare employing proprietary coupling coefficients. Designed for use as FOH# mid-top for live events, bars, and nightclubs and as stage / DJ monitoring this mid-top is compact and tonally accurate. Although driven actively by default, the A112 can also be availed with an integrated proprietary crossover network utilizing a dependable overdrive protection network.
The A112 is available in two versions… the HR (High Resolution) or the ER (Extended Range). While the HR requires an 18″ sub to cater to the low end, the ER has extended LF response eliminating the need for a sub if the situation calls for it. The A112/HR is recommended for use with the A118s or the A218s sub in the ratio 1 top to every sub.
