Alto Professional TS15S 15" 2500W Powered Subwoofer

Thunderous Low-End Power for Any Venue
The Alto Professional TS15S 15" 2500W Powered Subwoofer is a performance-grade sub designed to give your sound system a true low-frequency foundation. Armed with a massive 15" driver and a 2500W Class D amplifier, the TS15S delivers thunderous bass that adds muscle to your sound — from kick drums and synth drops to cinematic sound effects.

Whether you're playing live shows, DJing high-energy events, or building an immersive sound system, the TS15S gives your audience not just sound — but sensation. It’s the kind of bass that fills the room and moves the crowd.

Consistent Clarity at Every Volume
One of the most frustrating aspects of live sound is subwoofers that distort, rumble, or overpower your mix when pushed hard. The TS15S eliminates those issues with intelligent DSP-controlled limiting, a custom front-ported cabinet, and high-excursion driver technology.

The result? Deep, tight, and controlled bass that remains crystal-clear even at high SPLs. Whether you're in a packed venue or an open-air setup, the TS15S ensures every low-frequency hit is powerful but never muddy.

Plug-and-Play Versatility for Seamless Integration
The TS15S is built to adapt to your setup with stereo XLR inputs and outputs, user-selectable DSP crossover settings, and customizable output modes that pair effortlessly with Alto’s TS4 series or any full-range PA speakers.

A standard pole-mount socket allows for vertical speaker stacking, while the contour EQ switch fine-tunes the low-end response depending on the event — from live bands to DJ sets to corporate presentations.

Rugged, Road-Ready Design for Pro Users
Built for real-world use, the TS15S features a durable birch plywood enclosure, protective steel grille, and side-mounted carry handles for easy transport. Its rugged build not only improves acoustics by reducing unwanted resonance, but also ensures long-term durability in tough touring environments.

Whether you're loading in and out of venues or managing event setups across locations, this sub is designed to withstand the demands of professional use — without sacrificing performance.
