Accuton logo

The Accuton BD50-6-039 is a 50mm midrange / tweeter with a CVD diamond dome in a 106 mm square chassis.

CVD is an acronym for Chemical Vapour Deposition, a very complex process whereby a diamond is synthesized by deposition from a mixed gas (usually hydrogen and methane) onto a substrate at a temperature of around 800°C.

As the diamond dome is incredibly hard, the breakup frequency is at an astonishing 30 kHz and is way outside the audible spectrum, therefore no damping of the dome is required.

CVD diamond is the hardest known material and offers unsurpassed rigidity as a domed diaphragm. The electrical energy to transient sound conversion is the most accurate offering a new level transparency and resolution.

The BD50-6-039 features an FEA optimized underhung motor comprising a powerful Neodymium magnet and a vented aluminium voice coil former guaranteeing minimal energy wastage and excellent heat transfer.

This tweeter has an incredibly wide frequency range of  800 Hz - 30kHz.

We recommend a crossover frequency above 800 Hz / third order 18dB.

This exquisite tweeter is hand built to order - please contact us for a lead time.
