TW022WA07/09 and TW022WA08/10 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
