Wavecor TW022WA10 22mm chambered neo textile tweeter, 4Ohm – PAIR
Overview:
TW022WA10 are true high-end tweeters designed for the most demanding applications featuring an array of performance improving details that participate in obtaining low resonance frequency, low distortion and very high frequency extension
Features:
- Precision textile dome ensuring extended response and very good consistency
- 22 mm voice coil design with high power handling and low resonance frequency
- Copper foil clad center pole yielding very low voice coil inductance for reduced distortion and increased high frequency output
- Vented through to a damped rear chamber for low resonance frequency and low distortion
- Optimized light-weight dome for ultra high frequency cut-off, high effeciency, and improved transient response
- Vented voice coil former for reduced distortion and compression
- Copper-clad aluminium voice coil wire offering lower moving mass for improved efficiency and transient response
- Built-in cavities under dome/edge to equalize pressure – for lower distortion and lower resonance frequency
- Flexible lead wires for higher power handling and larger excursion
- Gold plated terminals to prevent oxidation and ensure long-term reliable connection
- Delivered with foam gasket attached for hassle-free mounting and secure cabinet sealing
