TW022WA05 is a tweeter designed for applications requiring the highest level of performance and most extended and linear high frequency response.
Innovation Tweeters used to feature a separate rear chamber in order to obtain low resonance frequency. Not any longer. By designing the internal parts to accommodate new larger internal volumes, the TW022WA05 offers an unusually low resonance frequency. The design with 22 mm voice coil and wide surround caters for both applications that would normally require traditional ¾” tweeters and those, where 1” tweeters would usually be used.
FEATURES
22 mm design for optimal compromise between on- and off-axis frequency response, resonance frequency, and power handling
Internal volumes for low 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 aluminium 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
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
