Thanks to its highly efficient Class-D amplifier, the TS18S 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 TS18S subwoofer is built with reliable durability in mind to be the anchor of your setup and sound. Constructed 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 18-inch driver and 3-inch voice coil, the TS18S 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 TS18S 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 low-frequency enhancement 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 settings or setup. Dedicated input and output channels allow you to seamlessly 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 correct 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 plugged on with the 35mm flange end.
