AC 6511 | 6.5" 2-Way Coaxial Car Speakers

The AC 6511 from the Alpha series provides a simple yet highly effective upgrade over factory speakers. This 6.5-inch coaxial pair combines the woofer and tweeter into a single, easy-to-install unit, delivering the renowned German Maestro sound with minimal fuss.

Affordable High-Fidelity

The AC 6511 features a rugged metal-basket woofer with a polypropylene cone for clear mid-range and mid-bass. The integrated 0.75-inch tweeter uses a pure titanium dome, made in Germany, to reproduce high frequencies with brilliant clarity. It's a high-value package that brings premium sound to any vehicle.
