Tectonic LS-212 Subwoofer

It’s difficult to believe that such a compact subwoofer can produce such accurate low frequency response. Designed to complement the Tectonic PL Series of flat panel loudspeakers and other mid – high speaker systems, the Tectonic LS-212 is a compact dual band-pass subwoofer. Comprised of two asymmetrically sized chambers, they’re optimized to deliver the highest possible output from the smallest possible footprint. The two 12” drivers are forward-facing to deliver higher-order harmonics above crossover frequency.
