Incredible Active Line Array Speaker!

QSC's incredible KLA12 line array speaker combines astounding power, amazing flexibility, and road-ready dependability in a surprisingly lightweight package that sounds absolutely stunning. The KLA12 is powered by a 500W x 500W module that provides plenty of clean, clear power to the 12" LF driver and the 1.75" HF compression driver. Ar-Q frequency optimization lets you tune the KLA12 to the array; in fact, you can adjust for the number of speakers in your array and get the most out of your KLA12 (it allows for up to five enclosures). You'll also appreciate the SOLO rigging system, which allows you to set up the speaker without tools or hardware. If you choose pole mount the speaker, the onboard Tilt-Direct mount lets you position the KLA12 perfectly for any room.

Wow.

I have to say, I was not expecting this system to do so well. I am absolutely astounded at the quality of this line array system. Combine 4 of these units with a sub on top, hang them on either side of your venue and get ready to experience a loud and clean sound. I frequently work with dance groups using our venue and they never complain about the volume and I still have quite some room left on the fader. Those speakers produce crisp highs and have great low end response. One of the huge pluses for me at least is the fact that these units are powered. No more bulky amps clogging up your rack turning your work area into a mini furnace and a mess of wires!

Mini rig bold sound

If you ever heard those Vertec 4889, this QSC KLA sounds similar but in a smaller scale. I have been a big JBL fan, but those VRX's turns me off specially the powered version. Recently sold all of my SRX series and I wanted something scalable, easier to deploy. Of course with good sound quality. I have auditioned these KLA and I was blown away by the sound. This is not the same as those K or KW series like a lot of people would think that it's the same module or drivers. This is a totally different animal than you would think off. I have four of these KLA12 and four KW181, they just sound incredible! Some say that the K or KW sound better but you will need to properly tune these KLA. Don't just throw anything on these speaker and expect the presence like those trap boxes. It's really easy to tune these and they do have a high gain before feedback, which is a plus. This rig is a keeper and the only speaker that I can replace these with either Vertec 4889 or much better Meyer sound.

Excellent!!

I recently installed six of these boxes, three per side in a 300 seat theatre room. Installation was extremely easy and quick. The sound quality we were getting was incredible. There was detail in the mids and highs, and the low mids were super smooth. I would not hesitate installing more of these in the future.

Tone +

I have been using kw153's for my system's mid highs for the past 2 years and loved the sound of them , however was looking for more scalability and coverage . I am currently using 4 kla 12s taking the place of 2 kw153's and I am blown away by the coverage and Tone of these speakers . Looking forward to adding 2 more and some lifts .

Great product

This is a great product. It is very well built. Supper easy to rig. I tested two of these boxes with one kw181 in an 1200 seet room and was blown away. These boxes can hold their own. The auditorium would need 4KW 181 speakers and 8 tops to have proper coverage. But I had no problem hitting 100 plus db 100ft from the speakers in the room. My favorite thing about this speaker is they don't sound harsh. My jbl prx 600 sound harsh at the same volume. Kw181 with these hits harder then my jbl srx 2 18" subs. Love the product and will be buy more for installs.
