So i'm in a smal project studio, and it probably goes without saying that it's not the most sonically balanced room in the world, but I am using HR824's and i just purchased the 1280 Mackie sub that goes with it. I love the sound of those monitors and the sub sounds great with them, but I have heard/read that I shouldn't mix with the sub on unless i'm mixing 5.1 (which I am not.) Is this true? And if it is... Why is it? I understand the theory that if you're mixing down to stereo, it wouldn't include an LFE channel, therefore you shouldn't mix with it. But it seems like the sub aids in balancing my room out in the low end. Bass was pilling up several feet behind my mix position, but now it sounds and feels a lot more even with the sub. All this to ask: What am I missing? What problems will i run into? Is all of this a bunch of crap?
