Essential Information About the ALTO Professional TX12S Subwoofer

• Powerful and precise 12-inch active subwoofer, ideal for reinforcing the low-end foundation of your sound system.


• Class D amplification with 900 W peak (450 W RMS) and integrated DSP for clean bass even at high volumes.

Low-End Reinforcement Designed for the TX Series

Designed to complement the full-range speakers of the TX series, the TX12S naturally integrates with models like the TX408 or TX410. It delivers the essential low register for contemporary music while remaining compact and easy to transport.

Who Is It For and What For?

Mobile DJs, bands, bars-clubs, and small venues will find the TX12S a versatile subwoofer to gain impact and depth. Paired with a pair of active speakers, it extends the frequency range and improves overall clarity by offloading the satellites from low frequencies.

Quick Settings, Immediate Results

Thanks to the onboard DSP, the TX12S offers simple and effective adjustments. The two EQ modes "Live" and "Music" instantly adapt the response, while the selectable low-pass filter at 80/100/120 Hz and polarity inversion facilitate alignment with any satellite speaker. The level control features a center detent at 0 dB and a limiter LED to maintain control.

Durability and Performance for Everyday Use

The MDF bass-reflex enclosure, front port, and metal grille ensure reliable sound dispersion and resistance to road wear. The two side handles and 36 mm pole mount simplify setup, whether for live performance, rehearsal, or fixed installation.
