I attended a classic car show on Saturday & the DJ had a pair of the QSC K12s crankin'. I was really impressed with the sound from these. He told me that he too has received many compliments about the sound these produce.
Great thump & the sound carried very well.

Being that they had internal fans cooling them, he had no problem with them in the direct sunlight with 95 degree temps ...playing for 6+ hrs. nonstop. I told him about the problems I had outdoors with the speakers I had used and how they went thermal & shutdown after only 20 minutes. I asked if he has had any problems playing outdoors with the K12s. He said so far, they have been flawless.

Impressive.
 
Bill -
I have used EV SXA360's for outdoor events for years and never had them thermal out & shut down! I have done 6 plus hours events such as car shows. pig roast's, crabfest's, outdoor wedding receptions, etc with no such problems. They are workhorses. Often in direct sunshine. I love & trust my EV's every weekend.
 
MY SXA 100+ still rocking in the free world never a heating issue since I had them (5 yrs.) !00+ degrees for 6+ hours no worries. 20 minutes? Even if they had no venting or fan the ought to have survived more than 20 minutes. Something doesnt calculate proper for you guys.
 
I've used Mackie SRM450s for hours on end in the summer heat and never had a problem (no fan, just a large heatsink), so I agree there is probably an issue with what you used.. I don't really care for their sound however .. a bit exaggerated in the mid/highs, but they do seem to cut through background noise and can be heard a decent distance away. I am planning to swap those out for a set of K10/K12s or something similar in the near future, as I like their sound better and for me they seem to be a better compromise for the floor monitor/small system needs I have.

I have the K12's too - used them last night as a matter of fact (with the EV subs). Sounded awesome! Cranked the subs at the end of the night too! My subs are typically run at around 10.30 or so. Great sound alone or with subs! Love them K12's! Mine have been flawless too. After saying all that, I won't use my K12's at any of my car shows - IMO, there's not enough throw. I lend that job to some Peavey SP2's. Outdoors, I'm typically passive. Indoors, I tend to be more active than passive.
 
Love my K12s. They are dynamite for the real small venues, by themselves. They also blend nicely when I run them with my ELX 115s. They are a bit brighter than the EVs so they are a perfect compliment to the more mid-low range sound produced by the ELXs. Stacked them on top of the EVs the other night (on an elevated stage) and it killed.

Nope, it wasn't a problem with Mackies.
I had the Mackies & they NEVER went thermal on me, even playing in outside 105+ temps.
 
but come on 20 minutes in the sun even if the box was packed with mothballs and no circulation it shouldnt have shut down that quickly. I think you may have gotten a bad batch. Many folks are running EV loud and proud in Hot Hot Hot regions just like yours.
 
My buddy has the QSC and they are a nice sounding system though I havent heard them real loud to date though I hope to this fall or winter.

When it first happened, I returned it & they sent me a replacement. A few months later the replacement did the same thing. Turn it off & let it cool down & it will work fine...in the shade.

This has also happened to another local fellow DJ. He called me because he knew I had the same model. He told me that it happened to him at 10:00 AM!!

I decided to keep them & only use them indoors. They have great sound.
He told me that he can no longer count on them since they failed him during a gig, ....he sold his & bought another brand (QSC)
 
I've had my K-12's for about 1.5 years now with no problems. This year we had over 60 days of 105 degrees and higher. I used the K-12's several times outside in the sun with no problems. One day was 108 at a tennis match, and we ran them all day from 8am til 8pm. Never any problems.
 
contact EV or whomever you purchased them from EV doesnt take customer service issues lightly. Call Ben if you dont know who to talk to or contact. Trust me I know they are good for their word. Rick Ryan bought from a source which EV didnt have to honor repair or service and though we dont know the results yet they backed their product despite not having any real responsibility.
 
I haven't had a minute to test mine (ELX112P's, or the ELX118P's) in the hot sun yet so I don't know how mine will fair in the 90's / +100's. Hopefully they will be ok. Again, up until now, my passives take care of outdoor duty so if I continue on that path, my EV's / QSC's will keep on rockin' indoors!
 
the sound company I work for has had a ton of the Mackies
which we still use for MANY smaller gigs
but when we need speakers that look classier
and sound better...we use the QSC's
we've even used four of them as tops for live bands.

If I had the cash, that's what I would buy
