QSC KS212C Active Cardioid Subwoofer

General

A problem many audio technicians deal with regularly are scattered low frequencies. QSC seems to have found the solution with the K Cardioid active subwoofer by giving it a cardioid directional pattern. This means the sound is concentrated and aimed forward so no bass tones are lost via the sides or rear of the cabinet. As a result, the sound pressure at the front increases by 15 dB, giving you a more focused sound that allows low frequencies more space in the mix. You won't have to worry about placement, delay, or polarity—QSC does the maths for you!

KS212C: Innovative design

In order to achieve this, the K Cardioid has two 12-inch excursion drivers that fit in a 6th order bandpass chamber. This means you have a sort of line array, but of the subwoofer variety! You've got 2x 1800 watts of power at your disposal, which is enough to provide an entire venue with plenty of low tones. If you're taking this sub with you on the road, you can take advantage of its rugged aluminium handles and wheels. What's more, you can place the K Cardioid horizontally or vertically depending on where you want to use it, and you'll find M20 stand flanges on the top and side.

QSC already introduced the KS212C at NAMM 2017 and, following on from Musikmesse 2017, they've now announced the rest of the new K.2 series. The K8.2, K10.2 and K12.2 are the successors to the active speakers in the K series. They're easier to use, more versatile than ever and they look pretty good too!

More Bass with QSC K Cardioid Subwoofer and E Series

Thursday 12 January 2017 By Lizanne

With a regular subwoofer, you can often lose low tones. QSC has found the solution to that problem and named it the K Cardioid. They plan to officially launch this active sub at the 2017 NAMM show next week. It has a cardioid directional pattern at its core which effectively prevents low frequencies from escaping via the rear or sides of the cabinet, resulting in more bass and a higher sound pressure level!
