Product Description

QSC K12 Powered Loudspeaker

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, all full-range models (K8, K10, K12) are fitted with the identical 1.75" HF device 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.

Inputs, Outputs, Mixing and EQ

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 (full-range 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 (full range 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.

Extensive DSP

DMT (Directivity Matched Transition) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones. Intrinsic Correction, first featured in our high-end line-array products, maps 65-75 spatially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat band pass 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. Finally, GuardRail protection, the same technology introduced on the GX Series amplifiers, protects both the amplifier module and your performance from unnatural and destructive clipping.

Light & Rugged

K Series full-range models are housed in rugged yet light 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.

They look great and sound good.
Stephen P. Loynaz
They are very easy to handle and once they are in the tote bags you can carry them as bag packs giving you 2 free hands to carry other equipment.
The subtle nuances of the sampled instrument sounds comes through the QSC loud and clear.

Honestly, it's difficult for me to being a thought process on the sheer godliness of this speaker.

Well, heres a start. My bluegrass band recently bought two of these bad larrys, and they are unmatched in quality by anything (except this one stage setup that was all analog and hand made by a sound-man at Podunk Bluegrass Festival). These speakers put out 1000 watts each, and thats the truth. This power gives you the most head room to eq all you need to without compromising clarity at high output levels. We run a banjo, guitar, mandolin, fiddle, and upright bass through them and its as if there are 16 constant directivity horns absolutely putting an arena in its place.

The 12's have a very very solid amount of bass, we were deciding on whether or not to get these or the 10's and get the KSUB one day. The 12's are more then enough (but maybe one day the icing on the cake will be one of those KSUBS). I would recommend these speakers from the bottom of my heart. Their build quality is rock solid. Their sound quality is ridiculously precise and clear. Their output is higher than 4 or 5 average pa speakers. Yes they are pricy, but if you actually want to get something that you will /not/ need to upgrade, bingo.

This speaker is lightweight and sounds amazing. The plastic scared me at first but already ending my second year of almost weekly use and they still look great. I live in Northern MN and the cold doesn't affect the plastic. Keep in mind i baby my gear because i want to get many years of use out of them but well worth the money. I went with QSC over JBL because of the 6 year warranty they offer on there speaker lines. I have 4 pairs of speakers and still no problems. We do push them pretty hard most of the time too.

The K12 is the replacement to the HPR 122 and it sounds better, is just as loud and is about half the weight. I would highly recommend getting the padded bag to protect your speaker. The bag has shown minor wear from being slid across the truck bed, something i never do but sometimes the guys that work for me aren't as respectful. I'll be buying the K8 soon to use for outdoor wedding ceremonies. The only thing i don't like about this speaker is the lack of handles on both sides, it would have been easy enough to put handles on both sides.

On a side note i don't like length of the bags carrying straps.

7 of 7 people found the following review helpful By DJ Steve on April 3, 2014
Being a mobile DJ for 26 years and having used several sets of passive speakers in that time, I wanted to make sure I did my “homework” before I made the leap into powered speakers. My criteria for the powered speakers was that they:

- needed to be under 45 lbs.
- have enough power to do a mid-to-large event
- sound good when cranked up
- have the features I needed (flexible inputs, daisy chaining, etc.).
- have a good reputation (quality and warranty)

After compiling a list of prospective models, I took a weekend and listened to the models side-by-side (luckily, my local Guitar Center had just about all of them on display for me to test). For each speaker comparison, I:

- set all EQ to flat in the source, mixer, and on the speaker itself.
- made sure the level was compensated so that the loudness (DB output) to my ears would be the same when I switched between the speakers.
- positioned myself in the same position and distance from each speaker
- played the same source material in each (and varied the source material as necessary to get a balanced feel for what the speaker could do).
- played the speakers at varying volume levels

I tried all the top brands and models: Mackie SRM450v2, EV (SXA100+, EV ELX112P), JBL (EON515XT, PRX612M), Yamaha (MS400, DXR12), Behringer (VP1220D, B112D, B912Neo), QSC K12, and Peavey Impulse 12D.

During the testing, for any two given speakers, I would pick a “better sounding” speaker and use that speaker in my next comparison. After I reached the QSC K12 in my testing, I liked the sound so much that I used that as my “reference” speaker from that point on and went back and compared it against all of the speakers I was testing.

I'm a mobile dj and a certified audio engineer so I take how I sound at every event very seriously. If your only interested in sounding like a club with nothing but a lot of distorted bass and just want something to get you by then maybe you should consider something else, there are other brands that can do that. My other system is a pair of Pyle Pro's and I got what I paid for. I was on a tight budget and did the best with what I could until I afford and save for something else. Seriously, this is an excellent quality product and I have many years working in audio experience. I suggest if your considering the K12's, go to a distributor and ask for a demo and test for yourself. Have a comparison of Mackies, Alto's, JBL or whatever they have to compare and then listen to the K12's. I could not believe the difference and was sold on QSC, I recently bought a pair and do not regret it. No issues with dropping out, overheating or rattles as other reviews said. Let me point out the K12's are NOT a subwoofer so don't treat them or expect them to act as one. They DO deliver a full range including some great bass even at lower volumes and if used correctly with a sub they blow other systems I have heard away. Are they cheap priced? No, but your getting a piece of equipment that not only sounds awesome it offers a wide variety of features that other brands don't and most of all my client's are happy. I don't miss lifting my huge boxes and amp's around and breaking my back compared to these, setup is now faster, easier and less stress plus I am proud of my investment.
