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 Avant 12A offers a multi-angle enclosure which allows it to be used in stage monitor applications as well as a compact P.A. system.

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, isn´t quality sound what it´s all about?

The 12AV4 loudspeaker designed and built by D.A.S. provides accurate low frequency reproduction. High frequencies are handled by the M-50N compression driver which uses a neodymium magnet structure and 2" titanium diaphragm-features hard to find on other systems in this market segment.
