Sound & Performance

With a 43Hz-21kHz frequency response, these speakers dig deep for impactful bass on bass-heavy tracks, while the 3/4-inch neodymium silk-dome tweeter keeps vocals and cymbals smooth and detailed, avoiding harshness on long drives.

90dB sensitivity means they get loud fast, filling cabins with room-shaking volume from factory head units or amps up to 100W RMS. The integrated crossover ensures clean separation between mids, bass, and highs for accurate staging.

Stable 4-ohm impedance pairs reliably with most car stereos, delivering distortion-free performance at highway speeds or parked tailgates.

Design & Battery

The ultra-thin design with 1-13/16-inch mounting depth and zero tweeter protrusion fits seamlessly behind factory grilles, complete with included hardware and grilles for a clean, professional look in US trucks and sedans.

Built tough with a polypropylene woofer, rubber surround, and neodymium magnet, they resist road vibrations and temperature swings for lasting durability on American highways.

No battery required; these draw power directly from your vehicle's system for unlimited playback during endless road trips, with quick installs saving hours compared to thicker competitors.
