The Alto Professional TX12S powered subwoofer packs a serious punch with its 900W, 305mm driver and Class D amplification. Designed to pump out bass in small to medium-sized rooms, it delivers powerful, clean sound that can transform any broadcast system. Its rugged MDF enclosure and DSP protection give it unwavering strength and reliability. Designed to adapt to different configurations, it features a selectable low-pass filter and two equalization modes, ensuring optimal compatibility with any speaker system. It is sometimes difficult to obtain a punchy bass without cluttering the space with disproportionate equipment. The TX12S takes care of the problem with a compact size and formidable power. Whether for a concert caf, a rehearsal room or a gym, it injects a good dose of sonic depth with ease.

It is sometimes difficult to obtain a punchy bass without cluttering the space with disproportionate equipment. The TX12S takes care of the problem with a compact size and formidable power. Whether for a concert caf, a rehearsal room or a gym, it injects a good dose of sonic depth with ease. Its 305 mm speaker associated with 900 W amplification offers a very real physical impact: you will no longer be content to hear the bass, you will literally feel it vibrating under your feet. A total immersion, without headaches or complex manipulations. The on-board intelligence of the TX12S is not limited to its sonic punch.
Thanks to its integrated equalizer and its selectable low-pass filter, it adjusts perfectly to the environment and the speakers that accompany it. No need to drown in obscure settings, a simple adjustment and you are ready for optimized diffusion. As a bonus, its polarity inversion switch helps prevent unwanted acoustic imbalances, because a subwoofer is made to roar, not to stammer. Designed to withstand repeated movements and installations, the TX12S is not only powerful, it is also built like a tank. Its MDF casing absorbs unwanted vibrations and effectively protects the electronic heart of the subwoofer. Its side handles and ∅35 mm base make it easy to set up, while its metal grille provides reinforced protection against accidental knocks. With it, no worries: even in the most muscular conditions, it holds its ground and continues to send out meaty bass.
