Reply to I'm right about to buy two QSC K12s...

So I'm going to buy these today, got an awesome deal from proaudiostar, and I just wanted to ask a quick couple questions before I go ahead with this.

I realize I won't have a massive amount of low-end off of these, and I won't be able to afford a sub for a while. For bigger events there will be subs available and I can make that work out. But for house parties/events I put on myself or for my friends, there most likely will not be a sub available.

Will these be enough for moderate to large house parties? I play pretty bass heavy music, and I'd rather not spend a bunch of money I saved up for really underwhelming sound.

I notice these have a "Deep Mode", or setting used for when you do not have an external sub. I can't imagine they would provide this option if these speakers are useless in the bass department to begin with, I just have no way to listen to these beforehand and want to get an idea of how much bass I'm actually going to get. As for their sound signature versus other models in their bracket I'm really not too concerned about, from what I've heard about them I believe I will be satisfied.

So, in a medium sized room, at a probably pretty loud house party (anywhere between 30, all the way up to a big party of maybe 150 people) will these provide enough low end? I know this is all very subjective, but I really don't know who else to ask really.
