The D.A.S. ND-10 is a 1.5" diameter exit Neodymium high frequency compression driver with a 100 mm (4") diameter voice coil. A pure titanium diaphragm is utilized, avoiding dome fracture due to mechanical fatigue, common in other diaphragm materials. The magnetic circuitry makes use of a rare-earth Neodymium magnet. This allows for greatly reduced component weight and easing of mounting requirements. The copper-clad aluminium voice coil is edge-wound and thermal bonded to a Kapton former, which ensures resistance to high temperatures. The 4-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. Additionally, the 1.5" exit allows for direct coupling from the phase plug exit to the horn, greatly decreasing throat distortion at high drive levels.
