The Alto Professional TS318S is an 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 2000W into the 18" high-excursion woofer to produce a frequency response of 44 to 86 Hz with a maximum SPL of 133 dB.
The TS318S offers two XLR-1/4" combo inputs and two XLR outputs. The integrated DSP provides six settings for interfacing with other full-range speakers ensuring a tight and professional sound. Controls include a volume knob, a polarity reverse, extended low-frequency switch, and power switch. LED indicators allow easy identification of the selected settings and power, signal, and limit status. The clip, thermal, and transducer overdrive protection keep the subwoofer safe.
The internally braced plywood 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 TS318S ships with an IEC power cable.
