QSC K8.2 is a 2000 watt powered 8-inch 2-way loudspeaker from the K.2 Series. It pairs an 8 inch woofer with a 1.4 inch titanium compression driver, reaches 128 dB peak at 1 m, covers a wide 105 degree axisymmetric pattern and weighs 27 lb, with a built-in 3-input mixer and LCD controlled DSP.
The smallest K.2, with the same 2000 W amplifier and DSP as the 10 and 12 inch models.
The K8.2 uses the same 2000 W Class D power module as the rest of the K.2 Series, split 1800 W to the woofer and 225 W to the horn. A low-noise, variable speed fan keeps it quiet enough for speech, theater and worship rooms, and QSC's dynamics processing protects the drivers without audible squashing.
Its 105 degree coverage is the widest in the K.2 line, which suits short throws, small rooms and floor monitor duty where a performer moves around. The cabinet tilts back as a wedge monitor, and dual pole cups give a straight or 7.5 degree down-tilt on a stand.
Everything is set from the rear LCD and rotary encoder: factory presets such as Live, Dance and Monitor, crossover settings for use with a subwoofer, EQ, delay, and savable Scenes that recall a full setup. QSC's DMT and Intrinsic Correction tuning keep the response smooth across the listening area.

Who Is the K8.2 For?
Singer-songwriters, duos, DJs who want compact tops, churches and venues that need a powerful floor monitor, and installers who want a small, rigged cabinet with real headroom. It suits jobs where one person carries the speaker and it still has to keep up with a band.
How Much I/O Does the K8.2 Have?

| Input B | Locking XLR/F 1/4 inch combo, selectable Hi-Z (instrument) or line |

| Mix output | 1 XLR/M, line level mix of all inputs |
| Power | Locking IEC, universal 100 to 240 VAC, 50 to 60 Hz |
Do I Need a Subwoofer With the K8.2?
Not for speech, acoustic sets or monitor use, where its 59 Hz to 20 kHz response (-6 dB) is plenty. For dance music or full band playback, add a powered subwoofer and select one of the built-in crossover settings so the K8.2 handles the mids and highs while the sub takes the low end.
