The 12sHO is a front-loaded, vented active subwoofer built for studios that need to reproduce deep bass and the LFE channel of surround formats at high levels. It uses a 12" woven Kevlar woofer driven by a 400 W Class A/B amplifier, with a quad-vented front-firing port. Bass extends down to about 29 Hz and the maximum peak SPL is 123 dB.
For integration, it has combo XLR/quarter-inch TRS inputs for left and right, a separate LFE input and balanced XLR outputs for passing the signal on. A sweepable crossover sets the hand-off to the main monitors, a ground lift switch is fitted, and the high-pass filter can be bypassed with the supplied footswitch. Indicators show power, protection and limiter status.
The enclosure is reinforced MDF (18 mm and 36 mm) with a textured paint finish. The mains input is selectable between 110–120 V and 220–240 V. The cabinet weighs 49.7 kg (109.7 lb).
