The trimless DE-X 300 CDR high-end built-in speaker has been developed as a front speaker (L, R, center) for wall installation in home audio systems and media spaces. The sophisticated three-way system has a dispersion angle of 80°. Due to the targeted dispersion, the DE-X 300 CDR can reproduce speech very clearly even in rooms with long reverberation times.
Thanks to a precise balance and highly linear frequency response, natural reproduction of sound is possible even at high levels.
The DE-X 300 CDR is comprised of three parts. First, the elegant installation frame is mounted in the ceiling or wall. The speaker unit and the magnetic front grille are then installed. This enables reliable installation and retrofitting, even for complicated installation scenarios.
