Alto Professional TS18S 18″ 2500W Powered Subwoofer
Add tight, punchy low-end to your PA setup with the Alto Professional TS12S, a 18″ powered subwoofer designed to provide adjustable low-frequency reinforcement for sound engineers and DJs in live stage, theater, and club setups. Class-D amplification drives the 18″ high-excursion woofer to produce 2500W of peak power output and a frequency response of 27 to 111 Hz (-10 dB).
The TS18S offers two XLR-1/4″ combo inputs and two XLR outputs. The user-selectable EQ tunings (Off, Live, DJ) and the phase-alignment selector switch (0, 90, 180, 270°) allow you to fine-tune the subwoofers performance when integrating with full range tops, ensuring a tight and professional sound. The internally braced MDF cabinet features a front port and a 1.4″ mounting socket, while the integrated and recessed carry handles simplify transportation between gigs. The Alto Professional TS18S ships with an IEC power cable.
