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 café, 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.
