As with the rest of the Reference Series, the main focus of these subwoofers is ultra-low-distortion. Second, third, and intermodulation distortion are kept extremely low by utilizing three short-circuit paths within the motor structure. A durable aramid fiber spider and extensive venting throughout provide quiet and uniform excursion. The black anodized cone, rubber surround, and custom basket give this driver a unique, high-end look. Choose the high fidelity version for home systems when you are looking for clean, low bass and are not restricted by cabinet size.
