I went ahead and bought a pair a couple weeks ago. I already have K12, K10.2 and K8s. Why then?
Partially for the size, weight and cost. These fit into the same Gator speaker bag as the K10s, albeit a bit snug. The weight is very nice, noticeably lighter. They feel like the K8. I wanted something for my band gigs that had the low end extension near the K12 but smaller and lighter. These might be it.
In addition to regular sound gigs, I play in a trio where a number of our gigs need to be one trip load ins and I have: mains, monitors, bass amp, stool, plastic tub of all the cables, percussion stuffs and bass guitar on one cart. The CP12 are a touch lighter than the K10 and the hope was they'd have LF similar to the K12. I play kick stomper pedal on my right foot, snare on my left while playing guitar, bass and singing. the kick stomper needs at least a 12" to be enough for the venues we play. On bigger gigs I can take a single DXS12 sub. I also wanted to see how these CP series do with the intention of procuring a trio of CP8 for our monitor wedges. The CP8 would drop almost 40 lbs from the load in over our Yamaha 3x SM10v with Peavey IPR amp rig.
First gig: the CP 12 does have a pretty good bottom end and they're easy to put up on a stand.
The plastic is different than a regular K series. The K series has a pretty solid thick sound when you thump the cab. The CP is thinner but not as cheesy as a DBR12. No fan. We'll see how these do in the Ca sunshine next year.
So far the sound is QSC, which is to say pretty darn good. Clean. They're not as loud although I've not pushed them yet, it does take more to drive them compared to the other active speakers I own. If I get a chance, I'll do a side by side against K12 & K10. I've only used default so far. The HPF on "ext sub" is 80hz, we'll see how that works with a sub. The control panel seems pretty good. There are enough choices to dial in a quick change if you use those kinds of things. The horn does seem to be about 60-75 degrees-ish in a non scientific walk past.. I'm thinking these might make decent floor wedges with a nice inconspicuous profile.
I used them on a corporate gig sunday. Not a big test but they were easily handling the job. This weekend I'll give them a tougher test outside for an air festival sound system. They'll be one pair of Nine total speakers I'll put up. On a side note the K&M dual speaker yokes are very well made. I bought a pair to do two double speaker crank up stands.
