So, here's an interesting conundrum: KRK VXT4 moniotrs are $199 each at MF right now, normally $299. I have M-Audio AV40 monitors, which also have 4" woofers and half the wattage. I am starting to become disappointed in their accuracy - woofy midbass that dies hard at about 80 Hz, a generally undetailed sound, at least in my room. I don't mind a 4" LF monitor, especially when the 6" monitor in the series only extends down to 49 Hz instead of 55 Hz. The KRK 4" should show much higher quality bass and extension by perhaps a fifth below my current system. I recognize that I am mixing in a terrible location (near lots of glass, wall right behind the monitors, small bedroom full of odd furniture and gear), so some of my disappointment is there and not with the speakers, but they do have their limitations.
Which brings me to the interesting part. For $430 I can get the KRK ERGO system.
ERGO Room Correction KRK SYSTEMS
I don't expect gobs of first-hand experience with the unit (by searching for "ergo," all I learned is that I'm the principle user of that word on this site ), but I expect that some of you have used and maybe own some type of room correction hardware.
If we assume that the system works vaguely as advertised (EQ and phase corrections through the audio band as needed, measured by an included reference mic and assigned by proprietary software), I should be able to run S/PDIF from my Firestudio Mobile to the unit and correct the glaring phase issues and EQ problems. I'd still have anemic monitors, but the major issues of my space would be compensated for.
I'm not trying to be Bob Rock here, but I do want the most neutral environment in which to mix so that I spend less time worrying about translation. Which route will deliver more sonic goods?
The AV40's are decent entry-level monitors and really, really good PC speakers, but that's about it.
If you want to do serious mixing, you'll want to just upgrade your monitors man.
