Alto TX 18s

The Alto Professional TX18S is an active subwoofer with an 18" driver and a 900W Class D amplifier section, designed to deliver deep, punchy bass in a wide variety of applications. This high-performance subwoofer will enrich the sound spectrum of your PA system, and ideally complements an Alto TX4 speaker configuration. Whether you're a DJ or musician, or equipping a concert hall, club or nightclub, the TX18S will give you rich, immersive sound capable of filling any space.

Power and reliability

Thanks to an 18" driver with a 3" voice coil, the TX18S can handle the nuanced, deep bass frequencies that are often poorly reproduced by conventional PA speakers. Ideal for complementing an audio system made up of TX4 speakers, such as TX412 or TX415, the TX18S creates a powerful, well-balanced sound system, capable of adapting to a multitude of applications. The powerful 900W internal amplifier features circuitry and overload protection to ensure that your bass remains crisp and clear even at full volume.

Multiple output modes

One of the TX18S's most advanced features is its two distinct EQ modes (Live and Music) and adjustable low-pass filters. These options allow users to modify the subwoofer's frequency response to precisely match any speaker system and listening environment. These settings, designed to be simple and accessible, allow the equalization to be adjusted to suit the ambient acoustics at the touch of a button, avoiding the complexity of multiple, sophisticated controls.

Optimized for durability and performance

The TX18S is designed to withstand the rigors of use. The subwoofer enclosure is made of durable, resonance-free wood fiber, which actually enhances the unit's intrinsic acoustic qualities. What's more, this subwoofer and all others in the TX series are designed and tuned in the USA.
