Alto Professional TS12S 12-inch Powered Subwoofer with 2500W Class D Amplifier

The Alto Professional TS12S is a compact yet powerful 12-inch active subwoofer designed to provide substantial low-frequency reinforcement for professional audio systems. It serves as the foundation for a complete sound setup, delivering the necessary bass extension to complement full-range loudspeakers. The unit is engineered to handle demanding live sound environments, from concert venues to mobile DJ setups, ensuring that low-end frequencies are reproduced with clarity and impact without overwhelming the overall mix. At the heart of the TS12S is a high-efficiency 2500-watt Class D amplifier, which drives a premium 12-inch driver with a 3-inch high-temperature voice coil. This combination produces a maximum sound pressure level of 130 dB at one metre, offering serious output from a relatively compact enclosure. The cabinet itself is constructed from internally braced MDF, finished with a durable, mark-resistant splatter-spray coating to withstand the rigours of transport and frequent use. Versatile onboard electronics include selectable EQ tunings (Off, Live, DJ) for tailoring the low-end response to different applications, along with a phase alignment function to ensure seamless integration with main speakers. This subwoofer is ideally suited for mobile DJs, live sound engineers, and installers working in venues such as nightclubs, houses of worship, or concert halls. Its comprehensive protection circuitry—covering clipping, thermal overload, and transducer overdrive—ensures reliable operation during extended performances. With standard XLR and quarter-inch jack connectivity for both input and output, the TS12S can be easily integrated into existing PA systems. The inclusion of a 36 mm pole socket allows for secure mounting of compatible top cabinets, making it a practical and robust choice for anyone needing to enhance their system's low-frequency performance.
