The AMK QSA615 powered speakers feature a 15 watt Class D digital design amplifier, with > 75% efficiency for the main speaker, and a three companion speakers for quad system. The speaker is a full range, low distortion, coaxial transducer assembly that combines high performance, power handling and a very smooth response.

The loudspeaker driver, CX601, is one of the few transducers in the commercial sound industry that produces and meets standards required for recording studio use. AMK took this quality and has engineered it for overhead applications. Excellent dispersion, wide bandwidth, and a smooth frequency response make this the top choice for today's overhead commercial applications.

Among the range of applications for the QSA Series are educational markets, corporate boardrooms, and any use that benefits from direct input of the signal from the source. (i.e., ceiling mount projector)
