Wavecor TW030WA23 30mm neo tweeter, Tetoron/Graphene dome 4Ohm – PAIR
Overview:
TW030WA23 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 extended frequency response.
Features:
- Graphene reinforced textile dome with increased high-frequency extension, consistency, and temperature rating
- 30 mm voice coil design with high power handling, and low resonance frequency
- Copper 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
- Rear heat sink for increased long term power handling
- 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
