Sound & Performance

These 2-way coaxials excel in loudness, pushing 240W for vehicle-filling sound that stays clean at highway speeds. The polyethylene-naphthalate tweeters provide sharp highs and vocal clarity, cutting through road noise effectively.

Midbass from the 6.5-inch cones offers punchy rhythm without boominess, ideal for pop, country, and podcasts. Volume levels impress for the size, with low distortion even cranked up during tailgating or long hauls.

Wide dispersion ensures even sound across seats, though deepest bass benefits from pairing with a sub. Stable performance matches car audio demands perfectly.

Sleek black housings blend into any dashboard or door panel, with a compact 6.5-inch footprint for straightforward installs in popular vehicles. Rugged construction handles vibrations and temperature swings typical of car use.

No IP rating means they are built for in-car protection, not submersion or dust-heavy off-road. Lightweight design eases handling during upgrades.

Powered directly by your car's system, enjoy unlimited playtime without battery concerns - just connect and crank. Quick integration with 4-ohm efficiency means low draw on your alternator for all-day reliability.
