I catch your point, Mister, and I don't want to initiate another long discussion of flat monitoring here. Also, I'm guessing that you indeed have great knowledge than me on this subject. With all that said, though, I have to add a couple of related points:
First, your reference to flat monitoring assumes that acoustic environments are very similar. My own little home studio has very strange acoustics--it doubles as a dining room, actually--and I'm not able (unfortunately) at this time to change much. My studio rolls out when needed, and I need to make do with what I have.
But I'm no slouch when it comes to sound. As a part-time studio guitarist for the past 20 years, I've come to rely on a few professional reference mixes (e.g., some Steely Dan mixes) when setting up my recording space. I also used these when auditioning several monitors in the low-cost price range--i.e., I bought them, brought them home, then A/B'd them, and then returned all but the BX5s.
The minor EQ adjustments I refered to are indeed minor--just enough to bring my system in line with my strange little acoustic space. And In know it works because my first mixes using the monitors--along with the mixes of my reference CDs--translate quite well to to three other systems I use while mastering (quality home stereo, good car stereo, and cheap boom box). While auditioning models that allowed no EQ adjustment at all, I had problems that have disappeared after subtly aligning the EQ of my monitoring environment--without moving walls or adding baffles. I know it's a cheap fix, but that's about in line with my cheap (Yamaha aw16g-based) studio. Yeah. I'm just making do with what I have, and the BX5s have worked well on a budget.
That's my story, wrong or right, and no argument intended with you or anyone whith more know-how of working within the limitations of a cheap home environment.
Peace, and thanks for the input...
