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.

I am going to purchase more.

Great Speaker

All i can say is this Ray is A Little tough to Fly, However it is well worth the work. Installed 3 of these in a 200 Seat Sanctuary, All i can say is WOW They are 100% Worth every penny. No matter where you sit or stand you get 100% coverage.

QSC is the best

We have only had these for a month so I can't comment on long term durability yet but I can say that 4 of these matched with 4 KW 181 subs will blow away any bar band PA I've ever heard. Clear, clean and powerful. I'm very happy with these and recommend them. We play 80 shows a year and these are worth the price if you want next level sound.

A Must Have Speaker!!

I purchased 4 of these incredible speakers about 6 months ago now from Sweetwater sound. Wished I would've bought them a year or two earlier. Absolutely clean , powerful, clear HD sound quality here !! Can't say enough good things about these. I'm a Huge fan now! Can't go wrong here guys. Call your Sweetwater sound engineer today and order your own Kla12's. Props to QSC here!!

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!
