Wavecor TW030WA14 Tweeter neodymium 8 ohm

TW030WA13 and TW030WA14 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

• Precision textile dome ensuring extended response and very good consistency
• 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
• Internal volumes for low resonance frequency and low distortion
• Optimized dome shape for ultra high frequency cut-off
• 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
