Alto Professional TX18S 900W 18-Inch Powered PA Subwoofer

The Alto Professional TX18S moves serious air: an 18-inch high-output woofer with a 3-inch voice coil, powered by a 900-watt Class-D amplifier, projects deep bass into nightclubs, larger venues, houses of worship and event spaces.

Music and Live voicing modes let DJs and bands choose the right low-end character, and the DSP low-pass filter switches between 80, 100 and 120 Hz at 24 dB per octave for a smooth crossover to any powered top. Built-in DSP protection guards the driver at high output.

At 87.7 lb the cabinet has side handles and rear caster threads (casters sold separately), plus a full metal grille, splatter-spray finish and 36 mm pole socket.
