The AMK PSA801 powered speakers feature a 15 watt Class D digital design amplifier, with > 75% efficiency for the main speaker, and an identical second speaker (USA 801) that can be attached if desired.  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, CX801, is a full-range, low distortion, co-axial transducer.  Its excellent polar dispersion derived from a high quality broad pattern polyamide tweeter makes it suitable for foreground or background music 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 PSA 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)
