In defense of the QSC K's
They don't have "voicing"
They're not meant to color your sound. Just amplify.
Ummm.....
Actually, they do.
I work with QSC HPR's and K's every weekend. Love 'em. Great speakers for the size, weight and price. They sound better than most competitive PA speakers, and pretty darn good with bass.
But they are definitely coloured.
You have to be talking from a purely theoretical standpoint. Because if you had used them in the field or A/B'd them against some reference speakers, you'd know that they are far from flat.
Better than a lot of midrange PA gear, to be sure. But miles away from a good Hi-Fi speaker.
Also, I have one of Duke's bass cabs, the little 12" one. Back to back with a K12, and driven full-range by a kilowatt class power amp, it tears the K12 a new one:
- more volume before breakup, especially down low
- less compression on peaks at high volume
- less harsh and coloured when listening to recorded music
- lighter, including the weight of a separate power amp and preamp
Of course, Duke's cab is more expensive when you factor in the cost of separate amplification. But you definitely get what you pay for.
