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 spectrum. The Alto Professional TS15S is an active subwoofer that delivers powerful, punchy bass. The TS15S 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 spaces.
With an active subwoofer, every musical performance takes a giant leap into sonic balance with a perfect blend of highs, mids, and extended lows.
The Most Powerful Subwoofer Yet
Sound requirements can change from night to night, but the best in the business rely on consistent, reliable power whenever it’s needed. The TS15S is Alto Professional’s most powerful subwoofer to date, boasting an incredible 2500-watt output to bring concert halls to life, power nightclubs, fill 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 effective sound transmission, and a carefully crafted enclosure ensures truly uncolored sound reproduction. With its premium 15-inch driver and 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 harmonize with the rest of your speaker system? The TS15S is designed and engineered to integrate seamlessly into any system thanks to versatile onboard electronic switches. Quickly cycle through user-selectable EQ settings to activate, boost, or bypass the 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 allow you to easily connect your Alto Professional full-range speakers or other standard speakers.
Extremely Robust - Easy to Mount
With Pronomic spacer rods, you can mount tops directly on subwoofers—at the right height. Almost all subwoofers already feature a compatible mount. Depending on the version, the spacer rods can be screwed on with an M20 thread or simply slipped on with the 35mm flange end.
