Compact Yet Powerful Active PA Speakers from QSC

We'll sum up the QSC K8 active loudspeaker in a word: "WOW." When QSC came to Sweetwater to let us hear their K Series of speakers, we could hardly believe our ears. These extremely lightweight, 1,000W powerhouses will redefine your expectations of how a compact PA speaker should sound. They're loud, yes. But they have the kind of balance and clarity you expect to find in only the best studio monitors. And their wide dispersion means everyone in the audience can hear clearly. Your portable PA rig doesn't have to sound small when you're equipped with QSC K8 active loudspeakers.

Built-in DSP for tailored sonic performance

QSC packed in tailored EQ switches and DSP, so you can adjust the K8's sound to whatever you're doing. Our favorite is the DEEP switch. Flip it on, and you've got an unbelievable bass response from an 8" speaker. You can always add a sub if you want true full-range response. Use the Vocal Boost to give the mid-frequency area more presence or keep it flat for "what goes in is what comes out" honesty. Other clever touches include the switchable LED light if you find it visually intrusive, simply turn it off. You can even have the LED work as a Clip Limiter Circuit indicator, so the sound engineer knows what's going on, even from the back of the room.

Smart input/output options

The QSC K8's combo XLR and 1/4" TRS inputs accept both Mic and Line Level input while a set of RCA phono inputs make it easy to hook up your portable MP3 players, CD players, and line-level mixers. Up to three audio sources can be mixed internally and summed to a balanced output for "daisy-chaining" of multiple units — very handy. Plus separate direct outputs are also provided on each channel for even more flexibility.

Dual-angle pole socket for more positioning options

When you're playing to a smaller room, it's often better to angle your speakers down towards the audience as opposed to firing straight into the back wall. QSC K8 speakers feature a Tilt-Direct pole socket that makes it easy to angle the speaker downward 7.5 degrees.

Small unit, BIG sound!

For an 8" speaker, this thing packs a punch! The range is ridiculous on this speaker as it hits the highest of highs and the lowest of lows in Deep Mode. Two of these K8's worked out perfectly at a wedding of 120 people. Would definitely recommend these to anybody who is looking for a high-end speaker.

Replaces older heavy equipment

I purchased this to replace a cumbersome and heavy keyboard amp. Very easy to move around with the K8 tote that I also purchased. Very clear with plenty of power. Highly recommended.

Paradigm changer

My K8 doesn't look like what it sounds like. Bass is incredible and clarity uncolored and crystal clear. Register on the QSC website for double warranty (6 years). Pricey, but money well spent. I am saving to buy a 2nd.

K8 surprisingly powerful

Just got a pair of K8s to supplement my friend's KW153s for an event (lecture) we do each year. last year the KW153s were adequate but way loud in the front and soft in back. With the K8s placed on the sides at halfway point we had a balanced fill in the whole room with the gain set at the same point on all 4 speakers. That was with voice - I played some background music during set-up and could barely turn up the mixer, tons of volume available. On the other side - i am now using them as near-field monitors in my basement studio and they are accurate even at lower levels.

These things are ridiculous! "Very impressed"!

Purchased two of these to use as front fills in our church sanctuary which seats approximately 400, and the results are incredible. We have had multiple complements on how the room sounds since adding these little QSC K8 speakers. The salesman was very helpful and professional. I look forward to working with Sweetwater again soon.

Sweetwater Advice

Austin Moss

If you can carry a baby then you can carry these babies. At only 27 lbs, you have no idea how much weight the low end carries. The only indicator on paper of how fantastic these things sound is the 1,000-watt amplifier. The QSC engineers have defied laws of physics and genetics. There should be no way these 8" babies can sound this good and go this low!
