Description
21 mm Dome Tweeter 4 ohm, Large Ring Neo, Black Faceplate
The large roll surround technology of the Revelator Tweeters represents a breakthrough in overall performance, with outstanding off-axis response, high output capability and low resonance frequency. A large neodymium magnet system for high sensitivity is part of the design. Additional enhancements have been made to reduce distortion and dynamic compression, such as a careful design to optimise airflow in the chambers.
Features
- Patented Symmetrical Drive (SD-2) motor
- Neodymium ring magnet system with double vent.
- High frequency extension beyond 40kHz
- Coated textile diaphragm w. large roll Surround
- Back chamber with high consistency felt pads
- Anodised Machined Alu Face Plate
