CABINET -- MODEL 828 This A7 Loudspeaker cabinet is hand made from 13 layer Baltic Birch and covered with a durable black splatter finish. The prime reason for an enclosure or baffle is to separate the sound radiated from the rear of a low frequency loudspeaker diaphragm or cone so that it does not cancel the radiation generated by the front of the cone. The enclosure is designed as a component of an acoustical system. A properly designed cabinet cannot make a poorly designed loudspeaker operate satisfactorily, nor can a well designed loudspeaker perform efficiently when housed in an inferior enclosure. LOW FREQUENCY WOOFER - 15" MODEL 515. HIGH FREQUENCY COMPRESSION DRIVER - MODEL 902. HIGH FREQUENCY SECTORAL HORN - MODEL 511B 90° X 40° Sectoral Horn.
