Description
Dual ring radiator tweeter features the patented dual-concentric diaphragm with a precision waveguide centre plug, providing excellent on- and off-axis response. Its ring radiator geometry and advanced motor deliver smooth, wide-frequency dispersion, making it a revolution in tweeter design. Rear chamber to extend low-frequency response. The faceplate has five recessed mounting holes. Eliminates dome resonance. Lower moving mass for high transients. Reduced distortion energy.
