Alto Professional TS18S 18" 2500W Powered Subwoofer

Earth-Shaking Power with Studio Precision
The Alto Professional TS18S is a force of nature in the world of subwoofers — combining sheer power with refined audio performance. Equipped with a massive 18-inch long-excursion woofer and driven by a 2500W Class D amplifier, the TS18S delivers deep, authoritative bass that transforms any performance into a full-body sonic experience.

This isn’t just bass you hear — it’s bass you feel. Perfect for high-impact events, live performances, DJ sets, and fixed installations, the TS18S adds intensity and depth to every beat, drop, and rumble.

Built to Overcome Real Audio Challenges
Many subwoofers fall short when the volume rises. They distort, boom, or lose definition, especially in larger spaces. The TS18S solves these common issues with DSP-controlled dynamic limiting, custom port tuning, and a rugged, acoustically optimized cabinet that delivers clean, punchy bass at all SPLs.

Whether you're working in a club, auditorium, or outdoor venue, the TS18S provides consistent low-frequency performance — eliminating muddiness and keeping your mix focused and balanced.

Seamless Integration Across Systems
No matter your setup, the TS18S fits in effortlessly. Its dual XLR inputs and outputs allow for straightforward daisy-chaining with other speakers, while the adjustable DSP crossover makes it easy to blend with Alto's TS4 tops or any professional PA system.

The contour EQ switch lets you tailor the low-end response for different types of performances, whether you're backing a live band or pushing heavy-hitting DJ tracks. The standard pole-mount socket allows vertical stacking for compact, high-impact stage setups.

Road-Tested Durability with Installation Flexibility
Transporting gear is often a pain point for live professionals. The TS18S solves this with built-in side handles, a tough birch plywood enclosure, and a steel grille that protects the internals from damage. Whether you're moving it between venues or installing it permanently, the TS18S is built to take a beating and keep performing night after night.

Despite its size, the subwoofer is intelligently designed for optimal weight distribution and portability, giving touring engineers and rental teams the confidence they need.

Ideal for Professionals Who Need Serious Bass
If your events demand more than just sound — if they demand impact — the TS18S is built for you. It's ideal for:

• Touring DJs needing deep, clean bass for dance floors
• Live bands and engineers looking for low-end that translates in large rooms
• AV rental houses wanting reliable, scalable low-frequency solutions
• Worship venues and theatres requiring impactful bass without muddying the mids
• Club and lounge owners who want to upgrade their low-end permanently
