Plus One Patented Woofer Cone: HARMAN's patented Plus One design delivers greater cone surface area than rival 6.5 in woofers, producing higher sensitivity and deeper bass without needing an amplifier Edge-Driven Silk Dome Tweeter: The full edge-driven silk dome tweeter provides a broader, smoother high-frequency response than standard w-dome designs, staying clean and natural at every volume level True 3-Ohm Low-Impedance Design: Maximises power transfer from any factory or aftermarket head unit by compensating for system resistance, giving noticeably louder and cleaner audio without extra hardware Laser-Etched Glass-Fiber Cone: Infused with ten percent glass fiber and formed in a laser-etched mold, the woofer cone delivers resonant, distortion-free bass and a striking carbon-fiber visual effect Complete Kit, Easy DIY Fit: Every component is included — woofers, silk dome tweeters, external crossovers and grilles — for a straightforward drop-in upgrade into standard 6.5 in car door locations
