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 TX18S’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.

The subwoofer’s enclosure is made from fiberboard that is durable, 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.
