Alto Professional TS12S Active Subwoofer

The Alto Professional TS12S is a high-performance active subwoofer that packs an impressive 2500W (Peak) of power into its compact enclosure. This model is designed to fill concert halls, nightclubs, and houses of worship with powerful and deep bass. The unit features a high-quality 12-inch (305 mm) woofer with a 3-inch high-temperature voice coil, ensuring accurate and controlled low-frequency reproduction.

This model boasts advanced tuning capabilities. Users can choose from three EQ settings (Off, Live, DJ) to tailor the sound to the event type. The unique Phase Alignment function allows for not only standard polarity inversion but also intermediate values (0°/90°/180°/270°), ensuring ideal compatibility with any full-range loudspeakers.

The cabinet is constructed from sturdy, internally braced composite MDF, which eliminates unwanted resonances. The surface is treated with a special "mark-resistant splatter-spray" finish, which maintains an excellent appearance even after intensive use.
