- Diamond Array Pattern Woofer Cone. It enhances sound and reduces distortion.
- Sound Field Enhancer. The unique shape of the tweeter creates a strong frontward sound as well as a wider sound field in 5kHz and upper frequencies.
- Acoustic Sound Harmoniser. It harmonises different sounds from the woofer and tweeter and reproduces a natural sound.
- Factory Location Fit. The tweeter height is designed as low as possible, and the speaker units can fit within most of the spaces for factory speakers.
- Black-Painted Woofer Yoke Plate. It efficiently releases heat inside the magnetic circuit and prevents the temperature of the voice coil from rising, resulting in improved durability.
- New Shape of Woofer Damper. It minimises mechanical stress and makes the sound response smoother.
