The Dayton Audio Reference Series subwoofers take the quality and
performance of the much acclaimed RS line into the subwoofer realm. 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. The High Output (HO) drivers are
optimized for automotive applications and equalized high-power home
subwoofers.
