Description
26mm TPCD Tweeter 8ohm, Black Faceplate.
The Revelator Tweeters' large roll surround and TPCD dome diaphragm technology represents a breakthrough in overall performance, with outstanding off-axis response and low distortion, high output capability and low resonance frequency. Additional enhancements have been made to reduce distortion and power compression, such as large neodymium magnet systems for high sensitivity, and a careful design to optimise airflow in the chambers.
Features
- Bespoke tailored Thin-Ply Carbon Diaphragm (TPCD)
- Rear Mount Magnet System
- Patented Symmetrical Drive (SD-2) motor
- Titanium Voice Coil Former
- Black Anodised 120mm Machined Alu Faceplate
- Non Resonant Aluminium Rear Chamber
