Alto Professional TX12S 900-watt 12-inch Powered Subwoofer

Alto TX12SXUS 

Description

The TX12SXUS is a powered 12″ subwoofer designed to deliver deep, powerful bass — ideal for augmenting full-range PA speakers in live setups, events, parties, or gigs. It uses a high-output 12″ woofer with a 2″ voice coil and an internal Class-D amplifier to produce low-end frequencies that standard speakers often can’t reach. Built in a rugged, ported enclosure with carry handles and pole-mount socket, it’s road-worthy and easy to integrate into different systems. Its onboard DSP and EQ/filter controls let you tailor bass response to suit either recorded music or live instruments.
