QSC K12 Powered Speaker Produces "Club" Sound In Compact Enclosure!
The QSC K Series is quite simply The New Standard in lightweight powered loudspeaker systems. Under the direction of Pat Quilter, QSC's team of amplifier engineers have created a new standard in Class D power modules unparalleled in the industry. Next, breaking from the traditional loudspeaker paradigm, every model is fitted with the identical 1.75" HF device (fullrange models) and woofers of the same high quality for unparalleled performance, regardless of speaker size. Extensive DSP processing is employed throughout, providing levels of sonic clarity and total output that defy the system's size and weight. Premium-grade materials, advanced construction processes and multiple mounting and suspension options allow for a wide range of live and installed applications. Combo XLR and 1/4" TRS inputs accept both Mic and Line Level input while a set of RCA phono inputs (except KSub) allow additional connectivity to 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. Separate direct outputs are also provided on each channel for additional output flexibility. On-board switches provide preset EQ settings. The HF setting (fullrange models) can be set to VOCAL BOOST for additional presence in the critical mid-frequency area or FLAT for accurate reproduction of the incoming signal. The LF switch can be set to NORM, DEEP™ for additional bass extension, or EXT SUB (fullrange models) for use with an external subwoofer. The rear panel LED switch can be set to POWER, illuminating the front-mounted LED when the unit is powered on, OFF for applications where it is not desirable to illuminate the front LED, or LIMIT which indicates to the system operator that the clip limiter circuit has been engaged during operation. Fullrange models are housed in rugged ABS enclosures with a professional appearance that is at home in any application. ABS is a far more robust material than conventional speaker plastics and offers an additional measure of sonic clarity due to its internal rigidity. Ergonomic aluminum handles and a highly protective steel grille complete the package for ease of transport and long term durability. The K Series fullrange models feature a unique Tilt-Direct™ pole cup mounting system. A simple turn of the dial engages a 7.5 degree downward tilt of the speaker allowing acoustic energy to be kept on the audience and off reflective surfaces for applications where maximum coverage from a high-positioned speaker is desired. Integrated M10 suspension points allow for suspended applications with a K SERIES M10 KIT (sold separately) or Yoke bracket (sold separately). The KSub is a dual-12" bandpass design, constructed of premium birch and includes high-quality, low-noise casters. The subwoofer features a threaded pole receptacle for a positive, wobble free connection to a threaded speaker pole (included). Remote gain control capability is offered via a potentiometer (not included) connected to the on-board Euroblock connector. In an installed application, multiple K Series speakers can be "daisy-chained" for total gain control from a single remote pot. Auto-standby mode is engaged after 5 minutes of inactivity.Features

- Intrinsic Correction™, first featured in our high-end line-array products maps 65-75 spacially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat bandpass target. The result is a speaker that behaves equally well across the entire sound field.
- DEEP™ and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.
- GuardRail™ protection, first introduced on our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.

I have used almost every kind of passive and powered speaker in the market so when the K series came out i was thinking to my self " they cant possibly sound as good as the mackie 450"
WRONGGGGG
Not only the k12s were much lighter and sexier then the mackies 450 that i used to love they have every possible input and output that you would possibly need, they sound amazing especially when DEEP mode is on.
with 1000watt of power you can push the ish out of them
i was soo happy with QSC that after purchasing 2 k12s i went back the next week to buy 2 ksubs and now i plan on purchasing another pair of speakers maybe the k10s or k8
QSC is the new industry standard hands down

Comments about QSC K12 2 Way 12" Powered Loud Speaker:
I have got to say, these are great speakers for the size. I have gotten a lot of compliments for the size and sound. I have 2 k12's with 2 kw181's. I have done a crowd of 250 easy with the gains at 12. I've also done gigs with these alone, and they did very well. The DEEP bass is great. I didn't believe at first until I've used it..it comes in handy when I don't need the subs. But, get the covers...you'll be grateful. I'm glad I puchased these. With the casters, I put both 12's on with my mixing console and just wheel it in to gigs. I don't need my handtruck anymore..unless there's stairs..lol. I've always used 2 peavey sp4's with a SP218 and 2 crown 4000 to push them, now I have less setup time and less weight on my back and less storage. 22 yrs of DJing has gotten much better..Thanks to QSC K & KW series. I prob will get the KW152's for bigger events 300+. One last thing, I did push these to go red (clip) for a good couple minutes..and it DID NOT stutter or shut off..that's my take after owning them for the past 6 mos. Hope this helps, I depended on reviews before purchasing myself.

Comments about QSC K12 2 Way 12" Powered Loud Speaker:
These speakers are very versatile. I bought these speakers after years of lugging around an amplifier for my speakers, now I have the convenience of both in one. I am able to play music via my IPod directly through the speakers while I continue to set up my main system. I used to play piano and now I can practice again by using this speaker as my amp. The speakers are very stylish, easy to transport and mount. The sound quality is outstanding and easily can fill a large room if needed.

Comments about QSC K12 2 Way 12" Powered Loud Speaker:
First, QSC has come a long way in the Audio industry, always being high quality. Starting with the amps in the Cabs, they are super reliable, and run very cool. The cabs have a Celestion Mid/Bass drivers in them, and produce a super clear, crisp sound. The HF Driver is so accurately tuned, any where you are listening to the speaker(s) it sounds so nice. With these cabs, you do not need to put a ton of power through them to get a nice sound. The inputs are a huge plus, you can run 3 different wires from all different sources through 1 speaker. The effects are very nice too. DEEP adds a lot more bass and lower frequency to the speaker, when switching the vocal boost adds a lot more HF to the compression driver, for the extra clarity. The ABS sounds full and warm, but is a scratch magnet, so GET CASES, to protect your major investment. Add a powered sub for the gigs that require more bass response, and songs that have a low frequncy root. The Ksub is good, but the KW 118 sub is really the way to go. The bass coming out of the K12 is good, but not sub bass, and you will hear that when you listen to them. Over-all, this is by far the best speaker I have heard, compared to the JBL PRX 600's, RCF's, Mackies, and Bose. It is easy to move around, and just the most practical for really any application.

Comments about QSC K12 2 Way 12" Powered Loud Speaker:
When you're for hire and DJ for a living, you quickly learn, you buy & use the best and most reliable gear you can afford. Your reputation, your business, rides on every gig.
I heard a pair of K8's at a local event. I couldn't believe my ears. Wow, just wow! The next day, I was at my distributor who demo a pair of K12 on top of a pair of K-Subs. The clear mids & "punch you in the chest" lows were without peer. Nothing even comes close.
Within a week, I sold my JBL SRX 715's and 718S along with three QSC PLX2 3602's and purchased the K12's, K Subs and factory covers for all. I've done about 25 gigs so far, half of which I only used the K12's by themselves. Largest gig indoor was for 550 (wedding reception) and outdoor gig for 1,400. Worth every hard earn penny I spent for them. I've never pushed them past 50% power, never had to.
Don't listen to me, listen to these speakers. But keep your eyes open, cause you won't believe you ears!

Comments about QSC K12 2 Way 12" Powered Loud Speaker:
I wrote a good review earlier about these speakers....but I have to add that I was a little skeptical about taking them outside with out subs.....Boy was I wrong. They held there own at a block party and was even heard three blocks away. Great sound quality and good thump with out a sub..even outdoors. Excellent Speaker....Worth every penny. The new standard.

These are incredible speakers and we have over a dozen in stock in our production company. We use them for everything from conferences with public speakers to dj events to concerts. However I have had a couple of them with no fault on the part of us blow. 1st had a woofer blow even though the audio signal was only half way up and the 2nd the amp blew yet again with the audio less than half way up.

Comments about QSC K12 2 Way 12" Powered Loud Speaker:
Absolutely brilliant. I've been a DJ for around 12 years now and this is the total package. After selling off all my gear a few years ago. I've decided to go back to my DJing habit. I worked in a sound shop for quite a few years and I know my gear. I've heard them all from no-name cardboard cabinets to Mach line arrays. THESE SPEAKERS ARE INCREDIBLE. Great design. Huge output without hogging power, Beautiful, accurate sound without weighing as much as a baby elephant. Lots of DJ friendly extras like a tilting stand mount and a locking power cable. Can't come up with a downside. These speakers rock, but, you probably don't want to "test" them at home, in the living room, at 10 pm...woke the neighbors, waaay more headroom then I expected. QSC, I love you.

Comments about QSC K12 2 Way 12" Powered Loud Speaker:
I have been in the DJ business for about 20+ years and I have used a variety of Speakers: EV, JBL, Peavey, Crate, Mackie just to name a few. However, I just brought the K12 by QSC.....and it is like OMG. Trust...these are well worth the investment. Before I brought them...I heard them side by side all of there potential competition for that category and they blew them away (JBL, Yamaha, Cerwin Vega, Mackie & Berhinger)....however, on a side note...those new powered 15" Berhinger's where giving JBL a run for the money to be 2nd on my list. But if you have the money...go with the QSC. You will be glad you did.

Comments about QSC K12 2 Way 12" Powered Loud Speaker:
OMG... QSC did it again. These are by far the best speaker I have ever heard. I was searching for a replacement for my mackies SRM 450. I bought the SRM 450V2 and those speakers sound like garbage. Took them back and got the JBL 515 EON. Those were ok, but I was still missing that serious punch and power. Enter the QSC K12 Series. This speakers deliver on every sense of the word powered speakers. I should have purchase this speakers from the beginning. After all I owe the HPR 152 and the HPR 15 Sub woofers. Move over Mackie...K series is the new standard on powered speakers.

Yes, 1000 is there peak. And they run around 500 watts continuous....however, if you have to push them a little...they won't clip on you. Great speakers that will hold its on under pressure.Answered on 4/18/2010 by DJ Dev aka Robert The Bruce from Chester, PAA:
According to the specs the QSC K12 is rated at 1000W continuous and 2000W peak. Not that it matters much, QSC is famous for engineering, they produce speakers that are extremely efficient, so the wattage rating is very deceiving. They perform way past what you'd expect. If you can, test drive them first. If not, just buy them, you won't be disappointed.Answered on 6/18/2010 by DJ Perez from Columbus, Ohio
