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
