Alto TS 12S Active Subwoofer 12" - Rock-Solid Sound from Bottom to Top!

The best performances demand the best sound coverage across the entire frequency spectrum. The Alto Professional TS12S is an active subwoofer delivering powerful, punchy bass. The TS12S subwoofer complements your full-range speaker setup, adding a strong yet controlled low-end presence for a comprehensive and complete listening experience in modern public music venues.

With an active subwoofer, every musical performance makes a huge leap into the realm of sonic balance with a perfect blend of highs, mids, and extended lows.

The Most Powerful Subwoofer Yet

Sound reinforcement needs can change night to night, but the best in the business rely on consistent, reliable power whenever it’s needed. The TS12S is Alto Professional’s most powerful subwoofer to date, boasting an incredible 2500 watts of power to bring concert halls to life, energize nightclubs, fill houses of worship with instruments, and much more. Thanks to its highly efficient Class-D amplifier, the TS12S adds the necessary weight to any public performance for a balanced representation of musical artistry in any environment.

Carefully Built for Quality Performance

A building is only as good as its foundation, and the same goes for your sound. The TS12S subwoofer is built for reliable durability to be the anchor of your setup and your sound. Crafted from premium materials, it features a high-quality, internally braced composite enclosure for dense, controlled sound.

Enjoy full sound without unnecessary rattling or buzzing. The key to bass is clear definition for impactful sound transmission, and a carefully crafted enclosure ensures truly uncolored sound reproduction. With its premium 12-inch driver and 3-inch voice coil, the TS12S subwoofer is built for tough live use—whether permanently installed or part of a mobile rig, night after night.

A Subwoofer for Every Environment

What good is a subwoofer if it doesn’t blend with the rest of your speaker system? The TS12S is designed and engineered to integrate seamlessly into any system thanks to versatile onboard electronic switches. Quickly toggle through user-selectable EQ settings to activate, boost, or bypass low-frequency emphasis depending on the demands of different shows.

Use the intuitive phase alignment feature as needed to ensure your tops and subwoofer work well together regardless of setup or configuration. Dedicated input and output channels let you seamlessly connect your Alto Professional full-range speakers or other standard speakers.
