Alto Professional TS12S | 2500W 12-Inch Active Subwoofer
Compact size, massive impact. The TS12S is engineered to add essential weight and "thump" to your performance without the bulk of a traditional 18-inch cabinet. Featuring a premium 12-inch long-excursion driver with a 3-inch high-temperature voice coil, this subwoofer produces a clean, controlled low-end down to 44Hz. With a peak SPL of 130dB, it provides the necessary headroom to fill nightclubs, concert halls, and houses of worship with rich, impactful bass. Housed in an internally braced MDF cabinet with a rugged splatter-spray finish, the TS12S is built to withstand the rigours of the road while delivering a tight, professional sound every night.

Professional Integration and Control
Seamless System Tuning The TS12S is designed to be the perfect partner for the Alto TS4 series, but its versatile electronics allow it to integrate with any professional PA. The dedicated "Speaker Use" EQ presets allow you to tailor the bass response to your environment at the touch of a button, while the Phase Alignment function ensures that your sub and tops are moving in unison to prevent "bass cancellation."
Built for Performance The internally braced MDF cabinet is a significant upgrade over plastic enclosures, offering a much tighter and more "musical" bass response. Whether you are providing a subtle low-end fill for a corporate presentation or a driving bassline for a crowded dance floor, the TS12S remains composed and powerful.

Frequently Asked Questions
Is this subwoofer powerful enough to keep up with 15-inch tops? Yes. While 15-inch tops have a lot of low-end themselves, the TS12S provides a dedicated 2500W of sub-bass that reaches deeper (down to 38Hz), taking the strain off your tops and significantly increasing the overall system headroom.
Does it have a built-in crossover? Yes. The TS12S features internal processing that manages the crossover between the sub and the outputs, ensuring only the correct frequencies are sent to your linked full-range speakers.
Can I mount a speaker on top of it? Absolutely. The TS12S features an integrated 36mm mounting pole socket on the top, allowing you to use a standard distance pole to mount your TS408, TS410, or TS412 speakers directly above it.
