Gearank Recommendation

The KS112 appeared on our recommended list for PA Subwoofers in 1 edition from October 2020 until November 2021 when it was removed due to being out-ranked by other subs.


QSC is well known for premium quality top rated loudspeakers, so it’s no surprise to see them doing well in the subwoofer market.

The KS112 represents them nicely, with its 2000W amplifier, 12″ LF driver, and built-in DSP that improves overall sound and adaptability.

With its variable crossover design and built-in correction tuning, this is a subwoofer that’s easy to implement in any setup.

It also features 6th order bandpass that allow for enhanced bottom end.

And it is housed in a rugged wood enclosure with heavy-duty casters.
