Description
The Peerless DFM-2535R00-08 is a high-performance 1” compression horn driver designed for pro audio and high-efficiency systems. It features a 1.4” proprietary titanium diaphragm with a polyimide surround, delivering smooth and detailed highs. Suitable for two-way systems with lower crossover points. All materials resist environmental factors such as heat, vibration, and ageing, ensuring many years of stable performance.
Features
- Proprietary coating on titanium diaphragm promotes a detailed yet non-fatiguing high frequency response
- 107.8 dB efficiency: high output relative to minimal input power
- Smooth response from an exceptionally low 1,500 Hz all the way to 17,000 Hz
- Polyimide surround provides durability and additional damping for natural sound quality
