Alto Professional TX12S Active Subwoofer

Alto Professional TX12S Active Subwoofer

The Alto Professional TX12S is a compact active subwoofer designed for musicians, rehearsal studios, and small clubs looking to enhance their low-frequency sound without investing in massive systems. The unit features a 12-inch (305 mm) high-excursion woofer with a 2-inch voice coil, powered by an efficient 900 W (Peak) Class D amplifier.

This model offers flexible DSP control options. Users can choose from two EQ modes ("Monitor" or "Live") and three low-pass filter (LPF) settings (80Hz, 100Hz, 120Hz), allowing for perfect integration of the subwoofer with any main speakers. The "Polarity Reverse" function helps to avoid frequency cancellation issues in certain rooms.

The enclosure is made of robust MDF, which reduces resonances and improves acoustic properties, while a special "splatter-spray" finish ensures resistance to wear and tear. The front is protected by a sturdy metal grille.
