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

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