"The Avant series incorporates an impressive battery of high tech features that take powered portable systems to a new level of performance. The latest in Class D power amplification, digital signal processing and optimized D.A.S. components have been combined with enclosures designed for ease of transportation and road worthiness. The 600 W Class D amplifier provides extended bandwith, improved dynamic range and exceptionally low distortion. This makes the Avant series one of the best sounding systems on the market. After all, isnt quality sound what its all about? The Digital Signal Processsing (DSP) incorporated in the Avant series provides unparalleled control over the audio signal. Critical parameters have been fine tuned for each cabinet, yet their consistent sound ""signature"" allows them to perform seamlessly with other systems from the Avant family. The 15AV4 loudspeaker designed and built by D.A.S. provides powerful low frequency reproduction. High frequencies are handled by the M-50N compression driver which uses a neodymium magnet structure and 2"" titanium diaphragm for exceptional perormance in all types of applications.
