There are so many aspects to good monitor design that I could seriously write a book. And frequency response is far from the whole story. However, the main things that you get from better monitors are:
1.
Lower distortion - often described as "transparency" and "detail."
2.
Less dynamic compression - a more "open" sound that actually lets you hear what you are intentionally doing to the sound with your compressor.
3.
Better impulse response - the sound is less smeared out over time. Also described as "transparency", "detail", and "sound stage."
Achieving a flat frequency response (measured in an anechoic chamber) these days is almost trivial. Especially with active monitors, you can just throw in a bunch of filters to smooth out all the nasty bumps and dips. $0.05 capacitors and $0.25 op amps are considerably cheaper than the high performance speaker drivers and low resonance cabinets required to "naturally" achieve a flat response - along with the qualities I listed above.
Translatability is important, but there are levels to this as well. Are you simply trying to translate well to average cheap consumer products, or do you also want to control the details inside your recordings that can be heard by the best playback systems in the world? Cheap "translatable" monitors will give you confidence that your recordings will sound decent on a variety of cheap systems. Excellent "translatable" monitors will give you confidence that your recordings will sound good on
anything - from a $10 boom box to a $10,000 dream system.
Subtractor,
I hate to say it, but I tend to agree that Yorkville's are rather "consumer". Not that you can go out and buy them where you buy consumer products, but in the sense that "consumer" is often used synonymously with "cheap". I design and build loudspeakers, so I'm extremely familiar a large number of component suppliers and their offerings. I recognize the tweeter used in YSM and it definitely leans towards the low end of the quality scale. The woofer is more difficult to identify since I haven't had the opportunity to open a YSM up, but typically a designer chooses components from the same quality range. And a simple tap on the side of a YSM box reveals a lot about its build quality.
Now, I'm not saying one cannot produce good mixes with Yorkvilles. And it's arguable that they have a good performance versus price ratio. But we shouldn't delude ourselves into thinking that they offer anything even remotely close to everything that one could ask for in a recording monitor.
Loudspeakers are by far the weakest link in any audio chain. And building them such that they perform to a meager one tenth the accuracy of even medium grade electronics quickly turns into an extremely expensive endeavor. Don't skimp on the weakest links - the devices that are almost literally the
ears to your music.
