Frequently Asked Questions

What is the QSC AD-S112sw?
The QSC AD-S112sw is a 12-inch ported surface-mount subwoofer reaching down to 30 Hz. It adds bass to AD surface-mount systems without a floor stand: a 12-inch weather-treated woofer in a vented enclosure with Q-SYS's turbulent-flow-reduction port, a 300 W rating and 115 dB continuous output. The included yoke mount couples it to the wall or ceiling, and Q-SYS suggests a 32 Hz high-pass and a 100 Hz low-pass filter.
What filters does Q-SYS suggest?
A 32 Hz high-pass and a 100 Hz low-pass, both 24 dB per octave Butterworth, set in the amplifier or processor.
Is it weather-resistant?
Yes, IP-54 for dust and splash, with a powder-coated aluminium grille and a galvanised steel yoke.
Does it have a transformer?
No. The AD-S112sw is a plain 8 ohm load with no transformer, so it connects to a power amplifier channel rather than a 70 V or 100 V line.
Which colours are available?
It is available in black (RAL 9011) or white (RAL 9003), with a powder-coated aluminium grille and a UV-resistant ABS enclosure.
How big and heavy is it?
It measures about 594 x 354 x 323 mm and weighs 13.2 kg, so it needs a robust structural fixing; the yoke mount is included.
Can Corporate AV supply and install the QSC AD-S112sw in India, and how do I get a quote?
Yes. Corporate AV supplies, installs and supports Q-SYS and QSC systems across India, with a site survey, commissioning and after-sales support. Use the Request a Quote button on this page or message us on WhatsApp.
