18" Active Subwoofer with 900 Watt Power and DSP!
The Alto Professional TX18S offers much more than just raw power. This unit can handle deep bass frequencies and reproduce them with flawless clarity and nuance in any large event hall, nightclub, house of worship, or retail space. DJs and musicians who need to transport their own gear from place to place will appreciate that the TX18S is optimized not only for mobile use but also integrates seamlessly into nearly any audio setup across a variety of environments and venues. Those installing the TX18S as a permanent fixture in their restaurant, bar, café, gym, or event space will be impressed by the device’s straightforward operation. The controls are simple yet effective, ensuring impressive reproduction of low frequencies regardless of your technical know-how or audio experience.
Sound Performance and Reliability
Thanks to an 18" driver with a 3" voice coil, the TX18S can process the nuanced low bass frequencies that are often lost when using standard full-range speakers. The powerful built-in 900 W amplifier features overload protection, ensuring that the low frequencies remain clean and clear even at full volume.
Multiple Output Modes
One of the TX18S’s most powerful features is its two distinct Live and Music EQ sound modes and selectable low-pass filters. This allows users to switch the subwoofer’s frequency response so it blends seamlessly with any speaker it’s paired with and the music being played. These streamlined, no-fuss parameters adjust the EQ at the push of a button to suit the environment, so you don’t have to wrestle with complicated, multi-layered controls.
Built for Durability and Performance
The TX18S is designed to withstand any wear and tear. The subwoofer’s enclosure is made from durable, resonance-free fiberboard that even enhances the unit’s acoustic properties. Furthermore, this subwoofer and all other products in the TX series are developed and tuned in the USA.
