Take it up a notch. With an Alto TX212S Active Subwoofer in your system, you can reinforce your low-end with confidence. Add power, impact, and depth to your sound, and create a perfectly-optimised system that is built to perform. Six selectable DSP output modes let you match your sub to your full-range speakers with ease. Each option (four TX2 series modes, Hi-Pass mode, and Bypass mode) adjusts the frequency response and crossover frequency of your sub. Ensuring that each of your system components works in harmony with each other for maximum performance. The TX212S's braced MDF front-ported enclosure makes sure that no low-end power is wasted. The cabinet prevents energy dissipating through its walls, keeping your sound tight and full. And with electronic clip, thermal, and transducer overdrive protection, you can push your sub to its limits and still enjoy that crystal-clear Alto sound.
