The ESB Audio 4.6C is a high-fidelity 2-way coaxial speaker engineered for precision and musical warmth. Combining a rigid pulp-cone woofer with a silk-dome tweeter concentrically mounted, it delivers clear midrange, smooth highs, and wide off-axis response. The optimized ferrite motor and cast aluminum frame ensure long-term stability, making the 4.6C ideal for both OEM replacements and high-performance aftermarket sound systems.
