In designing the C2 Coaxial and Component Systems, we have drawn from our vast experience in woofer design as well as the tweeter technologies employed in our world-class C5 component systems. The resulting products deliver a compelling performance solution at a price within reach of any enthusiast seeking a great listening experience.
