Monacor DT-300 Tweeter

30mm soft dome tweeter.


The Monacor DT-300 features a 30mm pure silk dome, a powerful double magnet system and a 116mm diameter faceplate. The voice coil is immersed in ultra low viscosity ferrofluid for optimal cooling whilst retaining a dynamic output characteristic. This larger tweeter is easy to work with, it has a smooth controlled output and a low resonant frequency.

We stock a horn adaptor for this tweeter here: Monacor WG-300.
