These professional speaker arise from the consideration of several factors affecting the sound of the electric guitar. By analyzing the behavior of existing amplifiers and speakers, we realized that the amplifiers have the expressive power and noise required by the musician, but radiant systems existing in fact limit this potential independently mounted speakers. The efficiency, dynamics, distortion and frequency response of amplifiers are so limited by the system on which they are mounted speakers: the speaker.

The challenge was to do justice to the guitar, his guitar and his amp without having to increase the power of the end of it let alone double or quadruple the number of speakers, as well as the weight and bulk end. More real sound, efficient, versatile, dynamic, but reducing the bulk and weight.
