ALTO - TX18S
The Alto Professional TX18S subwoofer doesn’t just shake the walls, it makes them vibrate with panache. Thanks to its 458 mm speaker and 900 W Class D amplification, it delivers deep and precise bass. Its integrated DSP optimizes the frequency response while protecting the system from excessive sonic enthusiasm. Whether you are a musician or a DJ, it adapts to all configurations thanks to its selectable low-pass filters and its two dedicated equalization modes. Built in a robust MDF cabinet, it combines solidity and acoustic performance without compromise.
Presentation
Nothing is more frustrating than high-performance equipment that is complex to adjust. With the TX18S, there's no need to juggle dozens of obscure parameters. An adjustable low-pass filter and two equalization modes allow you to adapt the sound reproduction according to the environment. A simple button is enough to integrate into your existing system without any hassle. With its XLR/jack ∅6.35 mm combo inputs and XLR outputs, it connects in the blink of an eye to any setup.
If transporting audio equipment could be an Olympic sport, the TX18S would be the athlete of the year. With its durable MDF cabinet, metal grille and side handles, it is ready to withstand repeated trips and installations without flinching. Its weight of 37.6 kg reminds us that it is not here to joke, but its rubber feet and ∅35 mm base ensure a stable and secure installation. Built to last, it will accompany musicians and DJs in all their sonic adventures, from small rooms to more ambitious spaces.
