Description
The Peerless DA25TX00-08 1” tweeter features an ultra-rigid corundum dome with resonance beyond the audible range. It delivers a flat response up to 20kHz with minimal distortion. An underhung copper voice coil, vented aluminium former, and deep rear chamber enable low resonance wide bandwidth. A copper cap reduces inductance and distortion. Ideal for low crossover points in 2- or 3-way systems.
Features
- Remarkably flat response from 1,000 thru 20,000 Hz (± 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
