AMK Commercial Series
QSA 802-MDL
Self Amplified 8” Coaxial Loudspeaker Assembly
The AMK QSA802-MDL powered speakers feature a 40 watt Class D digital
design amplifier, with > 75% efficiency for the main speaker. This unit is a
quarto system of 4 speakers, one powered speaker and three companion
speakers. The speaker combines high performance, power handling, and a
very smooth response.
The loudspeaker driver, CX602, is one of the few transducers in the
commercial sound industry that produces and meets the standards of
recording studio. Excellent dispersion, wide bandwidth, and a smooth
frequency response make this the top choice for today's overhead
commercial applications.
There are wide ranges of the application for this unit, especially in
educational markets and corporate boardrooms where direct input of the
signal from the processor is desired (i.e., projectors, laptops, or any line level
device)
Features:
 All metal construction, including baffle
 High performance 6½” coaxial loudspeaker with wide dispersion
 Self powered with 20 watt Class D amplifier
 UL Listed (UL 1480, UL 2043) PK-213-6 Enclosure
Innovative Features
Each system includes a renowned AMK Coaxial loudspeaker like those already installed in hundreds of locations
