Alto TX18S 900 watt 18 inch Powered Subwoofer with 18 inch LF Driver and DSP

900 Watts of Bass-boosting Performance

Do you need to bolster your bass? Of course, you do — thanks to its burly 900-watt Class D amplifier, the Alto Professional TX18S is definitely up to the task. This 18-inch powered subwoofer is a true behemoth, capable of filling any small- to mid-sized venue with ground-shaking low end. Moreover, the TX18S’s DSP-enhanced design provides a bevy of pro-level features, including EQ and system protection, Music and Live EQ voicings, a selectable lowpass filter, and polarity reverse. Here at Sweetwater, we’re impressed with the generous I/O on the TX18S, which includes XLR and 1/4-inch line inputs and balanced XLR line outputs. The TX18S is truly roadworthy, boasting a rugged front-ported MDF cabinet with internal bracing, a full-metal grille, and a mar-resistant splatter-spray finish. Finally, the TX18S includes side handles for easy transport and a 36mm pole socket for straightforward installation. When you need an easy-to-deploy sub that’s built to last, the Alto Professional TX18S stands ready to deliver the goods.

Sonic Power and Reliability

Thanks to an 18-inch driver with a 3-inch voice coil, the TX18S 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 circuitry and overload protection that will ensure your low end is clean and clear even at full blast. 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.

Optimized for Durability and Performance

The TX18S is built to withstand any wear and tear that may occur. 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.
