About Alto Professional TX12S

The Alto Professional TX12S is a powerful and affordable solution to producing ground shaking bass in small to mid-sized spaces. Perfect for musicians and small business owners, looking to revamp their rehearsal space or intimate performance spaces, this subwoofer powerfully extends the lower frequencies of just about any PA speaker and ensures a sonic experience that can be heard and felt in equal measure. In addition to being budget friendly and versatile, this unit was designed with ease at the forefront-the TX12S is simple to set up and built to last.

Sonic Power and Reliability
Thanks to a 12-inch driver with a 2-inch voice coil, the TX12S can handle the nuanced, deep bass frequencies that are all too commonly lost when using standard full-range speakers. The powerful onboard 900W amplifier comes equipped with overload protection that will ensure your low end is clean and clear even at full blast.

Multiple Output Modes
One of the TX12S's most powerful features is its two different Live and Music EQ voicing modes and selectable Low Pass Filters. This allows users to switch the subwoofers frequency response to seamlessly integrate with any speaker it is being used alongside and where the music is being played. These pared down and straightforward parameters change the EQ to fit your surroundings with the press of a button as opposed to having to fuss with complicated, multifaceted controls.

Optimized for Durability and Performance
The TX12S is built to withstand any wear and tear that may occur. The subwoofer's enclosure is made from fiberboard that is durable, resonant-free, and actually enhances the unit's inherent acoustic qualities. In addition, this subwoofer and all other products in the TX Series are designed and tuned in the United States.
