For a car speaker to excel it must be thoroughly engineered in all areas. The woofer design must deliver sufficient efficiency, smooth mid-range response and good low-frequency extension. The tweeter must be smooth off axis, exhibit good extension and be non-fatiguing, while the crossover design must seamlessly blend the sound of the drivers so that the end result is clean, realistic audio performance. 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. Specification Continuous Power Handling: 60 Watts Rec.
