The D.A.S. M-80 is a 2" diameter exit ceramic magnet high frequency compression driver with 73 mm (2.9") diameter voice coil. A pure titanium diaphragm is utilized, avoiding dome fracture due to mechanical fatigue, common in other diaphragm materials. The copper-clad aluminium voice coil is edge-wound and thermal bonded to a Kapton former, which ensures resistance to high temperatures. The 3-slit phase plug has been computer designed for coherent sound pressure summing at the throat. Manufactured out of aluminium, it acts as a heat sink for the voice coil, minimizing power compression and increasing power handling.
