ALTO PROFESSIONAL TX12S
 The Alto Professional TX12S is an active subwoofer equipped with a 12" speaker and a 
900W peak class D amplification section, designed to deliver present and powerful bass
in a wide variety of applications. Highly efficient, this subwoofer will enrich the sound spectrum
of your sound system and ideally complements an Alto TX4 speaker setup. Whether you are a DJ, musician, or equipping a concert hall, club, or disco, the TX12S will provide you with rich and immersive sound, capable of filling
the space. 
Power and reliability guaranteedThanks to a 12-inch speaker with a 2-inch voice coil, the TX12S can handle
nuanced and deep low frequencies that are often poorly reproduced by
standard sound reinforcement speakers. Ideal for complementing an audio system composed
of TX4 speakers, such as the TX408 or TX410, the TX12S allows you to create a powerful and balanced
sound system, capable of adapting to a multitude of applications. The
powerful internal 900W amplifier is equipped with circuits and overload protection
that ensure your bass remains clear and tight even at full volume. 
A complete and efficient interfaceOne of the most advanced features of the TX12S lies in its two distinct EQ modes
(Live and Music) as well as its adjustable low-pass filters. These options allow
users to modify the subwoofer's frequency response to precisely match
any speaker system and listening environment. These settings, designed to be
simple and accessible, allow equalization adjustment based on ambient acoustics
with a simple press of a button, thus avoiding the complexity of multiple and sophisticated controls. 
A robust and high-performance systemThe TX12S is designed to withstand all usage constraints. The subwoofer enclosure is
made of durable wood fiber, free of resonance, which enhances the intrinsic acoustic
qualities of the device. Moreover, this subwoofer and all other products in the TX series are
designed and meticulously tuned in the United States.
