Wavecor TW022WA02 22 mm neodymium textile tweeter, 4ohm – PAIR
Overview:
TW022WA02 is a compact 22 mm neodymium tweeter for applications, where small size is important, while still requiring the highest level of performance
The best of two worlds?
The design with 22 mm voice coil and wide surround caters for both applications that would normally require traditional 3/4” tweeters and those, where 1” tweeters would usually be preferred.
Innovation
In order to keep distortion and resonance frequency low the TW022WA02 is designed around a small external neodymium ring magnet to allow for a larger internal volume than that of traditional neodymium tweeters.
Features:
- 22 mm design for optimal compromise between on- and off-axis frequency response, resonance frequency, and power handling
- External ring neodymium magnet for lower resonance frequency and distortion
- Precision-coated textile diaphragm for improved consistency and high-frequency extension
- Optimized dome shape for ultra high frequency cutoff
- Vented voice coil former for reduced distortion and compression
- Copper-clad aluminum voice coil wire offering lower moving mass for improved efficiency and transient response
- Build-in cavities under dome/edge to equalize pressure – for lower distortion and lower resonance frequency
- High-stability ferro fluid for increased power handling
- 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
