QSC KS112 2000W 12" Powered Subwoofer

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.

Owners of this subwoofer describe the sound as being rich and deep, which is quite a feat given its smaller 12" woofer. Speaking of smaller, many appreciate its relatively lightweight design, while others are impressed because they didn't expect as much low-end from a 12" LF driver. Build quality and the extra mobility added by its built-in casters are also well appreciated. It has seen good use in the hands of musicians, band leaders, venue owners and more.

There are a few who aren't too impressed with its low-end, given its compact design.

If you want a reasonably portable subwoofer from a very reputable brand, then definitely check out the QSC KS112.
