Dayton Audio RSS460HO-4 18" Reference HO Subwoofer 4 ohm

The Dayton Audio Reference Series subwoofers take the quality and performance of the much acclaimed RS line into the subwoofer realm.

Second, third, and intemodulation distortion are kept extremely low by utilizing three short-circuit paths within the motor structure.
