AB  - A loudspeaker system with a large area (one square meter) and ultra thin enclosure (6 cm depth) has been developed. The system is composed of 4-way speakers including a pair of woofers, whose diaphragm dimensions are 78x28 cm each. To avoid a reduction in the sound pressure level of the low frequency range in wall mounting, a new type of enclosure (called twin-cabinet) which has an open and closed area for one diaphragm is employed. The four voice coils are applied to drive the woofer diaphragm as a result of the vibration analysis and acoustic field using FEM based on the acoustic load difference between the open and closed areas. The flat diaphragm consists of a five-layer structure, having a high mechanical loss owing to the Chitin reinforced pulp sheet used as a surface material.
