When the Avantgarde was first designed, it was based on a Signature model. The possibility of using an Air Motion Transformer in a totally new guise was no less than a revolution: One driver with a range from 2900 Hz to over 50.000 Hz!

NOT A RIBBON TWEETER BUT AN AIR MOTION TRANSFORMER
This was a dream come true. Instead of using a supertweeter with all the phase problems this causes, Ole Klifoth and his team could go all the way with one single driver. However, new research into the speed of a new midrange driver and cross-over was necessary to obtain a seamless transition from midrange to tweeter.

WE HAD TO INVENT A MIDRANGE TO MATCH

A new midrange with an unfiltered response up to 10.000 Hz was designed. With Audiovector’s own Air Motion Transformer, the Avantgarde tweeter – totally no- compression and used in a 30% rear firing SEC configuration – the pair form a very fast, very transparent, electrostatic like (but much more dynamic ) reproduction, which makes the best of every kind of music you present it to.

The SR 1 Super, and the SR 1 Signature can be upgraded to SR 1 Avantgarde, and they can all be upgraded to SR 1 Avantgarde Arreté.
