The rear panel features two combo XLR-1/4" line inputs and two XLR thru outputs to connect additional speakers. Refine your sound with the music/live voicing modes, selectable 80/100/120 Hz filter, and polarity reversal switch. The TX12S comes with the AC power cord.

Sonic Power and Reliability
Thanks to a 12" driver with a 2" voice coil, the TX12S can handle the nuanced, deep bass frequencies that are all too commonly lost when using standard full-range speakers. The powerful onboard 900W amplifier comes equipped with overload protection that will ensure your low end is clean and clear, even at full blast.
Multiple Output Modes
One of the TX12S's most powerful features is its two different live and music EQ voicing modes and selectable low-pass filters. This allows users to switch the subwoofers frequency response to seamlessly integrate with any speaker it is being used alongside and where the music is being played. These pared-down and straightforward parameters change the EQ to fit your surroundings with the press of a button as opposed to having to fuss with complicated, multifaceted controls.
Optimized for Durability and Performance
The TX12S is built to withstand any wear and tear that may occur. The subwoofer's enclosure is made from fiberboard that is durable and resonant-free and actually enhances the unit's inherent acoustic qualities. In addition, this subwoofer and all other products in the TX series are designed and tuned in the United States.
