The 12-SE subwoofer cabinet houses a 12 inch aluminum-cone woofer and a 300W amplifier with finned heat sinking. The bass-reflex design is ported beneath the cabinet, with tall polished-aluminum footers for bottom clearance. The 12-SE provides both line-level and speaker-level hookups, has volume and crossover-frequency controls, a phase toggle, and a lowpass bypass toggle.
