Beta Four has been a market leader in compression driver technology for decades. Our reliability and performance is second to none. We continue to work with a wide variety of materials to further improve the performance of our HF devices. Through our modeling programs, we are able to analyze every aspect of the driver and study the impact of key components on each design.

We use four different diaphragm materials: Mylar, pure Titanium, Polyimide, and High Temperature (HT) Polyester. Each material has its own unique benefits and qualities. Mylar allows for an exceptionally smooth transient response. Pure Titanium provides superb power handling and excellent reliability in the field. Polyimide achieves very high power handling and sensitivity levels and creates a smooth top end response. HT Polyester provides superior power handling and higher output levels in the upper octave ranges.

Standard features in our compression drivers include copper shorting rings, FEA optimized phase plugs, and edge-wound copper-clad aluminum voice coil wire.
