The THE15 Be PRO PASSIVE ON WALL is an extremely impressive and extraordinary performing musical speaker system, that leaves nothing to be desired. This 15"point source axisymmetric speaker has been designed as screen speaker for large theaters as left, center and right speaker or can be used for very large theaters as a surround speaker. ASCENDO's passive crossover technology paired with highest grade flat wound OFC copper air core coils and silver capacitors work in combination with the enclosure and coaxial driver design to deliver ultra-precise and incredibly fast impulse response.
