I was possibly the first in NH to adopt the k12s into my inventory. I was there to take the 3 pair off the truck when they came into the local banjo center equivalent. I took them home and decided to give them a quick listening test, very simple setup, ipod into the back of the speaker into the two 1/4 inch jacks.

One of the things that i first noticed when unboxing them was the signal diagram of sorts on the back, I found it quite helpful as it makes it easier to understand what goes through what. I took a pair of xlr's out of the direct out of sorts into the other k12 I had setup. First test, all settings flat, so no ''vocal boost'' or DEEP. Not too bad, sounded about like I remembered it at low levels, clean and smooth. So now it was time to crank it up a bit, about halfway up and one thing i notice immediately is how much it doesn't sound like a plastic speaker, it reminds me more of the HPR's I had grown to like enough but always left my back in a fair amount of pain. Now remember that here I have everything set at ''flat''. I decided to go into DEEP and WOW. The box started thumping along. At this point I am impressed, the box is running along smoothly, sounds like i have a sub under it. I push the box up to I would say about 75 percent power, still sound decent and is hitting hard, another 10 percent and thats when I felt the box started to struggle, the top end seemed to be falling apart a bit. I think I should mention that at this point I am well above the noise level I would ever need out of these boxes, If I needed this much I would bring out a larger rig

Overall reaction, these are a true SRM/eon killer. I know that there is better out there but at the time I bought the boxes, there wasn't for the money.

After at least a year and a half and easily 200 gigs or rentals on the boxes, they are holding up well. I am happy with my purchase and bought another pair 6 months later. They fill the dry rental/small sos/monitor need that I have and as far as I am concerned are exceptional for their size and weight.
 
Re: QSC K12

A local vocalist that heads up an acoustic trio asked me which speakers to get for their small lounge setup.

Having previous experience with the HPR series, but knowing she would not like the weight of them, I recommended the K series. I think she ended up with the K10s because of their small size and sole requirement of acoustic guitar and vocal reinforcement. She couldn't be happier, and neither could I. They sound absolutely amazing for the price and they weigh next to nothing.

My only complaint is that they take a while to power on... can be a little scary sometimes, like starting an old car that takes a few cranks. They always work though.

+1 to the K series.

I get to use the K-10's a lot around town, as many of the museums have them in their audio pools now as a replacement for their aging EON stocks.

Some have had them for the better part of a year now, and I still do the whole little dance... check the settings, flip the switch, walk a few steps away, don't see the light yet, walk back holding my breath... and then finally see the fan spooling up as the light slowly comes to life.

I'd have to rate them as the most ''laid-back'' cabinet, when it comes to power up time... they always kinda straggle in to work. :D~:-D~:grin:

I could not be happier though with the build quality, sound quality, overall weight and the feature set on the back panel is excellent for such a tiny cab.They make me regret buying my PRX-512 cabinets, every single time I use them.
 
Re: QSC K12

The fan is also delayed,so it could be the different parts of the amp coming online. I really wasn't sure if the delay was designed into the speaker or it was a result of the design.
 
Re: QSC K12

I always figured that delay was to keep a powerup surge from slamming them.

This is just a guess, but isn't it the DSP firing up? DSP based amps take a few moments too.

I would say yes, as the front light blinks once and the signal and clip lights blink, similar to what my XTI's do.

If i leave them running on low my fan only comes up for a second while the startup process is running, after that it's back off. It comes on when I push the box up above about 25 percent and will run, but if I pull it back it will shut back down after awhile.

Also, to add to my original post, One of my favorite features has to be the 7.5 degree tilt. I can not tell you how many times that has made my life easier. The monitor angle adds a lot of functionality to the box too.
 
Re: QSC K12

Very slightly off topic, but we have K8s and can report that they are also nice boxes, especially for their size.

It's probably to be expected in the 8'' version, but I find the sub boost settings to be pretty nasty sounding. I run the tops flat with a K-sub, and am very happy with it for all kinds of light reinforcement situations.

The K-Sub is a little surprising in its output level for the size, but is more of a ''whummmmmp whummmp'' slow thump than a wham wham hard hitter. It kindof tends to drone. It's very servicable - again, especially for its size - and we love it for small DJ jobs, coffee shop bands, and corpie spoken word stuff.

They are very musical sounding, much more so than either SRMs or Eons, which always sound exactly how you expect a plastic powered speaker to sound.

I bypassed the K8's completely when I was looking at them, The only 2 things I could ever see using them for are for a monitor or a smalllllll sos and seeing as they don't have a monitor angle and I can easily use a k10 or 12 for a small SOS.

Maybe we should change the title of this thread to QSC K series? Make it more of review of the entire line.

I agree that the K8 isn't very useful for anything. No monitor or front-fill angle pretty much makes them SOS only, and then they're going to be too small.



Back when K10s were out of stock nationally, I had to get four K8s instead of four K10s for front fills for a show. They rocked all over the place due to the curved side, and they were really hard to sell after since no one wanted them.



On a plus side, they do sound really good for an 8'' box, and the BE had no complaints.
 
Re: QSC K12

Actually I spec'd the K8 for an interesting venue, one that had a virtual reality cube (I put one K8 in each corner), and then a bunch of K8's mounted like ceiling speakers in a multipurpose event space. Worked beautifully, even took advantage of the remote control function to turn certain speakers off depending on head table configuration! I have 3 K12's for a LCR cinema arrangement at the front of the multipurpose space.

That built in tilt is slick. It's just the right amount too. I have some K&M tilt adapters that I used for other speakers... They are 15 degrees and are just way to much most of the time.
 
Re: QSC K12

Since I made the investment, I use my balanced tilters most of the time with my K10's. With a ultra tall stand, it really makes a difference in controling the levels in a smaller room.



As someone (I think it was Tim) said, ''Point the speakers where the people are''.



It is nice when the HF doesn't have to go through a bunch of peoples heads to get to the back of the room.
 
Re: QSC K12

I love the flexibility of the box. It works great as a monitor or a main. The built in tilt is an incredibly useful feature. The Vocal Boost function is nice, too when you just want to plug a mic and guitar into it and go.

Having the built in fly points is also a great feature for me to use in the future.

It sounds great. I haven't seen/heard a single powered speaker I'd rather own in the price range than my K12.
 
Re: QSC K12

Well, At this point in the game I thought an update would be a good thing. I moved from 3 pairs, to 4, and then to 6, So I have a nice inventory of all the same box, that can be used in monitor or SOS/main applications. 1-2 Pairs spend most of their time out on rentals or doing work at almost all times. It's been a while since I've had all of them at home at once. Looking back over the purchase and what I almost bought, and what I could have bought I feel relatively confident saying that I made the right buy. Are there better sounding speakers out there? of course, but I rent in bigger or better when I need it.
I send them out the door for $25/day with a 3 day week to dry rentals, with a credit card for deposit and I know that it would be near impossible for someone to blow them up, they have nearly every input on the back of the box for everything from a mic and music to a DI/ and a mic. They are incredibly easy to set up and understand the running of as well. They have definitely made their money and are one of the better buys I have made.
 
Re: QSC K12

Have you thought about adding a sub/subs to your fleet? If so, what about the KW181? Just curious. I have a pair of K10's, nice little boxes.
