QSC K12 12" Powered PA Speaker - 1000W (Discontinued)
The K12 was the biggest and the loudest of the three sub $1000 original K Series powered speakers from QSC, with a max SPL of 131 dB.
I have processed thousands of review sources for Gearank and rarely have I seen a product that is so consistently raved about by its owners as I have just now while researching the QSC K12 12" Powered PA Speaker.
It's popular with bands, DJs and audio engineers for use both as an FOH speaker and a stage monitor, but be careful as XLR plugs/cables sometimes fall out when using it in the floor wedge position. It's important to note that these were more expensive than many other options available (you could get some for close to half the price), which makes the high ratings it received even more impressive than they would ordinarily be.
It provides a total of 1000 watts via the Class D amplifiers and can peak at 2000 watts.
It has built in DSP (Digital Signal Processing) which performs a range of functions to keep the sound crisp and clear across a wide range of frequencies and volumes - one proprietary function is DEEP (Digital Extension and Excursion Processing) which allows it to produce low frequencies at volumes not usually associated with a speaker enclosure as small as this - some people even report they get a similar response to using a sub woofer.
It features a 12" LF driver that is housed in a bigger cabinet, which makes it heavy yet reasonably portable.
Another nifty feature of the QSC K12 is its dual angle pole socket, which lets you angle the speaker downwards by 7.5 degrees.
High frequency and Low frequency EQ switches are available, for fine tuning the sound to your preference, its most prominent feature being Voice Boost, which is ideal for speeches and for emphasizing vocals.
When analyzing reviews I looked hard to find negative comments about the QSC K12, there were some but there are few who consistently report the same issue - there were a few DJs that reported that they were hitting the power limit, but this seemed to be because they weren't using the correct inputs for the power level their mixer was putting out.
A thoughtful feature is that the power cable clips into place and can't be removed without depressing a release button - you don't have to worry about the power cable falling out when you're driving the speakers hard.
