Key Info
Alto TX212S is a 12" Active Subwoofer that features 900W (peak) Class-D power amp and 12'' transducer that deliver that signature Alto sound

Deep, defined, and rich

Give your sound the impact it deserves. Sometimes, a pair of full-range speakers just don't quite give you everything you need. Adding an Alto TX212S to your system lets you take advantage of a more powerful, extended low-end response, taking your sound to the next level.

The TX212S's 12'' transducer is driven by the sub's high-efficiency Class-D amplifier. Capable of producing 900W of peak power (450W continuous), the amp works in harmony with the entire subwoofer design to deliver that signature Alto sound. Every note is reproduced with phenomenal clarity, deliver a distortion-free sound that your audience will never forget.

Built with precision

No more resonance. And no more wasted acoustic energy. The TX212S's cabinet has been built to ensure maximum performance at all times. Crafted from rugged MDF with a braced design, the cabinet makes sure that none of the transducer's energy is dissipated through vibrating, resonant cabinet walls. Instead, every bit of energy is right where you need it, delivering your sound with impact and power.

The perfect match

Optimise your system. With a choice of six DSP output modes, you can ensure that your TX212S's response is perfectly suited to the full-range speakers you're using it with. Four of these modes have been tuned specifically for use with Alto Professional's TX2 series of full-range speakers (TX208, TX210, TX212, and TX215). The other two are Hi-Pass and Bypass modes. Whichever one you choose, the system adjusts the frequency response and crossover frequency, creating a perfect match for your speakers.
