A-Series Mid-tops

A115 ER/HR

SingLE 15" two-way bass-reflex loudspeaker

 

The A115 is a single 15″ mid-top loudspeaker mated to a 1.6″ compression driver which in turn is coupled to a 60° x 40° rotatable constant directivity flare employing proprietary coupling coefficients.

The A115 is a single 15″ mid-top loudspeaker mated to a 1.6″ compression driver which in turn is coupled to an 60° x 40° 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 A115 can also be availed with an integrated proprietary crossover network utilizing a dependable overdrive protection network. The A115 is available in two versions… the HR (High Resolution) or the ER (Extended Range). While the HR requires an 18″ or a 21″ 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 A115/HR is recommended for use with the A118s, A21s or the A218s sub in the ratio 1 top to every sub.
