Accuton 3/4" PURE DIAMOND DOME TWEETER

CVD diamond is definitely the best material available. Its stiffness to weight ratio is unsurpassed, the internal sound velocity unrivaled. However, due to high costs and serious technical hurdles until now Accuton could only make diamond tweeters and small midrange units up to 50mm in diameter.

• Response to @100kHz
• Extremely low harmonic distortion
• High sound propagation
• Ferrofluid loaded
• Flange 82 x 82mm

Accuton's Diamond Dome Technology

The BD20–6–031 is a 0.8 inch tweeter with ultra hard diamond dome in a 82 mm frontplate. As the dome breakup frequency is around 60 kHz, no damping cutouts are required. The unsurpassed rigidity of the diamond dome leads to most accurate conversion from electrical energy to sound pressure. An FEA optimized underhung motor design with vented aluminium voice coil former and neodymium magnet guarantees low energy storage and excellent heat transfer. The soft fabric surround and ferrofluid with high viscosity center the moving parts with excellent linearity. We recommend an application above 2500 Hz.
