Advance Acoustic
Advance acoustic was formed after the decision was made in Toulouse France, to create a new French brand with an idea which was both simple and audacious: to design audio equipment, reasonably priced but with faultless musical quality. Speakers were the first products off the production line, with 5 models becoming available.
These were an instant success and received high praise from many French magazines. In 2002, Advance Acoustic added electronics to their product catalogue, while keeping the same simple philosophy, reasonably priced without compromising on sound quality.
