Description
The Peerless DA32TX00-08 1¼" dome tweeter is designed for Hi-Fi and pro audio applications. Its ultra-rigid corundum dome ensures a flat response beyond 22 kHz, while a deep rear chamber and underhung motor improve power handling and dynamics. A thick copper cap reduces distortion, and an optional magnetic grille provides additional protection. Capable of handling crossover frequencies as low as 1200 Hz, this tweeter delivers outstanding performance in virtually any 2- or 3-way speaker design.
Features
- Remarkably flat response from 1000 to 22000Hz (± 1.5 dB).
- Large copper cap lowers inductance and minimises distortion.
- Underhung copper voice coil on a vented aluminium former with ample excursion capability.
- Deep rear chamber with integrated heatsink for low Fs and high power handling.
- Corundum dome is extremely rigid with excellent damping.
- Huge motor assembly provides excellent control and high efficiency.
