Alto TS 15S Active Subwoofer 15" - Rock-Solid Sound from Bottom to Top!

The best performances need the best sound coverage at every end of the frequency spectrum. The Alto Professional TS15S is an active subwoofer delivering powerful, punchy bass. The TS15S subwoofer complements your full-range speaker setup and adds a strong yet controlled low-end presence for a full and complete listening experience in the modern public music space.

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

The Most Powerful Subwoofer Yet

Sound reinforcement demands can change night to night, but the best in the business rely on having dependable power whenever it’s needed. The TS15S is Alto Professional’s most powerful subwoofer to date, boasting an incredible 2500 watts to bring concert halls to life, fill nightclubs, power houses of worship with instruments, and much more. Thanks to its highly efficient Class-D amplifier, the TS15S adds the necessary weight to any public performance for a balanced presentation 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 TS15S subwoofer is built for reliable durability to be the anchor of your setup and sound. Crafted from premium materials, it features a high-quality, internally braced composite enclosure for tight, 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 15-inch driver with a 3-inch voice coil, the TS15S subwoofer is built for tough live use—whether permanently installed or part of a mobile setup, 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 TS15S is designed and engineered to fit 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 what each show requires.

Use the intuitive phase alignment feature as needed to ensure your tops and subwoofers work well together regardless of setting or setup. Dedicated input and output channels allow seamless connection of your Alto Professional full-range speakers or other standard speakers.
