QSC K12 and KSub

Re: QSC K12 and KSub

Sorry Phil, it was described to me as a prototype and wasn't labeled. It was possibly the jf2000? But that is described as having a 10 and a coax 8 on the website. The system engineer said he didn't think it was listed on the website yet.

Phil and Jay,
what you were probably discussing is either the KF200NT which is the 10 LF with an 8" coax MF/HF, and the KF394 or KF364 which has the dual 10" LF with the newer MF/HF coax on the MK style horn....

Hi Joe-

You will want to talk to the marketing dept: the KF364/394 are listed as "line array element." Somehow I don't think so....

Have fun, good luck.

Re: QSC K12 and KSub

This is a problem, I think, for essentially all small powered speakers. If one of the companies made a control-less model that had the option of buying a plug-in minimixer and/or RF module, that could be an interesting distinguishing element. Pass on the decreased BOM to customers who don't want to pay for the extra knobs and dials.

The converse might be a product that sells more poorly in the prosumer space, which is where I suspect the majority of sales come from. No speaker maker is going to sacrifice thousands of unit sales to bands, little churches, DJ, political orgs, etc. for the sake of the comparatively small pro market.


Sticking with the 'is is good to rent theme" the K series cloth bags provide only a modest amount of transport protection.

The Mic/line function is only moderately useful. How many events can you get away with a single mic with no EQ?

The 7.5 tilt down function is well engineered, and when used appropriately can significantly improve a show. I really like it but for general purpose rentinal... how many renters will get it right?

As i have commented on before, the 1,000 watt has got to be mostly marketing hype. It's a 500W amp into a 2 ohm LF speaker + a horn. It still does a respectable job but it is what it is.

When used as floor monitors I have had the XLR fall out on a couple of occasions. This is pretty embarrassing and irritating. I don't know if it was careless insertion or vibration or something else.

I can say that on most shows where I deploy the K's I get very positive comments from the artists. One show was a fiasco... heavy metal with a "band engineer".
I deployed a couple only because I has a couple JBLs stolen. I think they may have shut down... I don't know the band was so freekin loud that I was in pain the whole time even with plugs in.
 
Re: QSC K12 and KSub

I own 2 HPR122i, an HPR181, and I'm pretty familiar with the K10s as a friend owns a pair for a Jazz trio (piano, acoustic guitar, female vocalist). I don't know anything about the KSub. So I have no direct experience with the boxes in question. I've mixed on SRM450s on several occasions. That said...

I've found the K10s to be much more than acceptable at their price point. I mix the female vocalist from the jazz trio on several different systems (Nexo PS10s and KF650zs) in another band. She uses the K10s when she's playing out with the trio and her voice sounds very natural on the K10s, maybe slightly midsy. I would choose this box over an SRM450 for light Jazz. I don't know about the K12. I would imagine the crossover between the high/low would be lower on the K12, and one would think that may help with the "midsy" problem. It sounds like from Phil's experience it didn't or it's worse in some other way.

I think HPR122is sound harsh at low volumes. For rock program, they work well. That's the only thing I'd use them for personally. For anything with a heavily compressed program or when you just want it plain loud, the HPR122i wins over the SRM450 as well, IMO.

I also own some Yorkville NX55ps. These sound better than all of the aforementioned speakers at low and reasonable playing volume, but I've had trouble with the durability of the knobs on the back. If you are doing something heavier you push them into solid limit, they are still 6 dB shy of the HPR122is and sound horrible doing it. Yet, they use the almost the same components!

My K-10's and K-subs doing an Elvis tribute at a car show yesterday.

Very nice coverage out to 100 ft and good sound even 90 degrees off axis.

Re: QSC K12 and KSub

Ian,

I cannot speak to the KW series, only the plastic k boxes. I've never used the KW. I don't mean for anyone to take umbrage at my opinion, and I am not sure how to reply to the rest of your message in a way that is helpful to the thread. I could trumpet opinions of others whose ears I trust, but ultimately it is a "he said she said" that benefits no one.

I think most of us here have done SOS gigs on gear they thought was lackluster, and SOS have always been more about roi than sound anyways. Almost every pa company I've ever interacted with has SOS and RF as their busiest pieces of inventory.

In Justice's case, he is about to spend his state upgrade allotment on product he hopes will exceed his old mackie(rcf) inventory. I'm merely commenting that he is unlikely to experience an improvement in subjective sound quality at the hands of the k series vs. RCF era SRM450. You'll notice that I in no way discouraged him from the purchase, but want to help him spend the states money wisely. Upgrading working kit with product of equivalent performance may not be the best way for him to spend his sparse dollars.

Valid points. I didn't mean to go on a tangent about the KW's but AFAIK the only difference between them and the K is the enclosure. One could ASSume that they would sound similar. Although I have not had a chance to A/B the KW122 vs. the K12 side by side, or measure them with any software (such as smaart).
 
Re: QSC K12 and KSub

For reference heres a pic of the KW122's and KW181's. Sorry for the poor quality iPhone pic. Setting up for a party of about 250 guests, dance music, no problem. could have used a little more bass for my liking.

Re: QSC K12 and KSub

I was quite concerned about the technique of this being deployed for main speakers, but then I happened to look a little closer and realize it was a side fill.... :?~:-?~:???: *dough* Work well for you though? I've had nothing but positive experiences with the K series, but I know they're not perfect and not the savior of the one man PA system.

In this case, the K-10 is vocal monitor for the brass section. There is another for the drummer. 2 EAW SM159z for vocalists.

Another K-10 was used as a texas headphone at FOH. It was too durned hot to wear headphones.
 
Re: QSC K12 and KSub

Has anyone had any luck with freq/phase response charts from QSC? I've asked our rep at least 4 times, and am told that QSC doesn't want to confuse their target market with facts. If there is nothing to hide, why not provide this?

I like K/KW for the price, but they definitely are voiced a bit 'off'.
 
Re: QSC K12 and KSub

Caleb, since you're an installer & designer I'd contact Pat Quilter directly. Tell him your firm's use of QSC loudspeakers depends on them providing the info you need. He'll either stir the pot or you'll know they aren't serious about providing the info you need to design systems using their products. Make your choice accordingly.
 
Re: QSC K12 and KSub

No speaker maker is going to sacrifice thousands of unit sales to bands, little churches, DJ, political orgs, etc. for the sake of the comparatively small pro market.

Which is why there are no "K Series PRO" version with only one XLR/Combo input an XLR male loop through, ONE recessed level control and Powercon AC connectors.

I'd buy them but realistically less than a dozen. Multiply me by all those with similar needs and wants and you get a number far lower than the bean counters need to modify their existing models, even if they charged $100 more a box for them.
 
Re: QSC K12 and KSub

Just curious - I wonder how often all the extra inputs and switches and knobs on the back of SOS speakers are a benefit, compared to how often they are simply more rope to hang oneself.

Oddly enough last Saturday the keyboard players monitor fried. I pulled a k-10 out and used both 1/4 inch inputs and the show went on.

Do you mean his amp fried, or his wedge fried? If his amp died, I'd just put him in the wedge and keep going. If not, I guess it was good that you had a powered speaker with 1/4" input.

I'm going to reply to Caleb and say that I wish every powered speaker was set up like the ADR stuff - XLR in and through, Powercon in and through, no knobs or anything else, not even a power switch.
