Hey,
I am assuming that with mixing you mean producer-style activities?
The thing really is that the two things you want, really don’t fit in one speaker. If you want “clubby” feel, you need something that will play loud, with plenty of lows and that you can listen too (loud) for a longer period of time. If things go loud, they usually suffer in the “exact replication” department. If you want “exact replication”, studio monitors are the way to go. Problem with those is, they are made for that, exact replication, not long term loud sound production.
In studio’s you will always see two or even three sets of speakers for that exact reason. They will mix on their (mostly smaller) near-field monitors and then listen on the bigger far-field monitors at high volumes.
If you do want them all in one, it’s gonna be a compromise one way or the other.
The QSC’s are good for the loud “clubby” feel but you will never get the clarity and definition that you will get from a studio monitor from them. An alternative to the QSC’s to look into are the Mackie HD-series (12″, 15″ and a 15″ 3-way). Same price range as the QSC’s. I have a set of 1221s with an 1801 subwoofer. I tested many speakers and to me the Mackie’s outshone most. The only thing I found came close were the Turbosounds.
Especially the 1531’s are a serious alternative when space is an issue and you can’t fit subs. Most active PA speakers today are two-way (bass and mid/high driver) and bi-amped (a seperate amplifier for each driver, two total). The 1531 is a THREE-way speaker and is TRI-amped (so three amps total). You get 700W (RMS) for the lows (15″) and 100W (RMS) for mids (6″) and 100W (RMS) for highs. Grand total 900W RMS! Maximum sound pressure levels a sickening 135dB. You do NOT want to turn those full power in a small room :-).
For the HD-series Mackie worked together with a company called EAW who did the sound quality engineering and managed to get a VERY good sound quality out of a PA speaker.
Again, worth checking out, trust your ears!
There are some other brands that deliver fantastic build quality, sound quality and power. A good example is Fohhn, a German manufacturer (they actually produce in Germany!). Their prices are steep though.
Good luck with your choice & greetinx,
C.
