Alto Professional TS15S 15" 2500 Watt Powered Subwoofer
For musicians and live sound engineers, a powerful, articulate low-end isn't just a luxury — it's the foundation of a great performance. The Alto Professional TS15S delivers that foundation with a room-shaking 2500 watts of power, providing the deep, controlled bass needed to bring your sound to life. Whether you're energizing a dance floor, reinforcing a rock band, or adding weight to a worship service, the TS15S provides a balanced and vibrant listening experience.
Power and Precision Combined
The TS15S is built to deliver serious low-end punch while maintaining the clarity and detail your music deserves. This subwoofer is engineered not just to be loud, but to be precise, ensuring your bass frequencies are felt.
2500W High-Efficiency Class D Amplifier: As Alto Professional’s most powerful subwoofer, the TS15S offers immense headroom. This means you get clean, undistorted bass even at high volumes, making it perfect for filling large venues without breaking a sweat.
15-inch Driver with 3-inch Voice Coil: The heart of the TS15S is its premium transducer, designed for exceptional performance and reliability. This robust driver accurately reproduces low frequencies, delivering the thump and impact that makes music feel alive, night after night.
Internally Braced MDF Cabinet: A great subwoofer cabinet should be sonically invisible. The TS15S features a front-ported, internally braced enclosure that minimizes cabinet vibration and resonance. This ensures the sound you hear is tight, focused, and free from unwanted rattles or muddiness.
Engineered for Any Environment
A subwoofer needs to be a team player, seamlessly integrating with your existing setup. The TS15S is equipped with versatile controls that make it easy to dial in the perfect sound in any environment.
User-Selectable EQ Tunings: Adapt to any room or genre with the push of a button. Choose between "Live" for a punchy, controlled sound, "DJ" for an extended, powerful low-end, or "Off" for a flat response when using an external crossover.
Phase Alignment Selector: Getting your tops and subs to work together is crucial for a coherent sound. The four-position phase alignment switch (0°/90°/180°/270°) helps you eliminate frequency cancellation and ensures your system delivers maximum impact.
Comprehensive I/O: The TS15S is ready to connect to any professional PA system. It features two XLR + 1/4-inch combo inputs for versatility and two balanced XLR line outputs to feed your full-range speakers. It also includes two XLR thru outputs for linking multiple subwoofers.
Built for the Road
Live sound equipment needs to be tough, and the TS15S is built to withstand the rigors of touring and frequent use.
Rugged Construction: From the sturdy cabinet to the integrated 36mm pole socket, every element is designed for durability.
Mark-Resistant Finish: The splatter-spray finish keeps the subwoofer looking professional, even after countless load-ins and load-outs.
Built-in Protection: Electronic clip, thermal, and transducer overdrive protection safeguards your investment, allowing you to push the system confidently.
The Foundation of Great Sound
The Alto Professional TS15S is more than just a subwoofer; it’s a crucial component for achieving a professional, full-bodied sound. By providing a solid low-end foundation, it allows your main speakers to work more efficiently, resulting in greater clarity and definition across the entire frequency spectrum. Add the TS15S to your setup and feel the difference.
