Wavecor TW045WA01 22 mm dome tweeter high quality

TW045WA01 is a unique new design, where a textile dome is combined with a ceramic cone in ensuring a larger bandwidth, high effeciency, and new levels of refinement and dynamics

.

FEATURES

Dual-Piston design combining a 22 mm textile dome with a 45 mm ceramic cone. Precision textile dome ensuring high frequency extension, ceramic cone adding low frequency output and efficiency

Copper clad center pole yielding very low voice coil inductance for reduced distortion and increased high frequency output

Front-side reflection reducing foam ring

Flat low-damping IIR surround

Vented through to a damped rear, die cast, chamber for low resonance frequency and low distortion

Alu chassis with built-in heat sink for increased long-term power handling

Dual-neodymium magnet structure

Optimized dome shape for ultra-high frequency cut-off

Underhung voice coil design for improved linearity

22 mm voice coil design with high power handling, and low resonance frequency

Copper-clad aluminium voice coil wire offering lower moving mass for improved efficiency and transient response

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
