  • Ring radiator tweeters offer superior break-up modes compared to similar dome diaphragm models. This means the upper frequency range tends to be cleaner (lower distortion) and offers more extended response than similar conventional dome tweeters.


Non-resonant diaphragm design for minimum high frequency break-up


Dual balanced compression chamber for improved dynamics


Copper cap for reduced voice coil inductance and minimum phase shift


Saturation controlled motor system for low distortion

Feature 5

Flow optimized vented pole piece for optimum coupling to rear chamber
