But hey - monitor selection is pretty subjective...
Yeah, but should it be?
I like to think of my monitoring system as a bank statement. I want it to tell me exactly what's in there. I don't want my bank statement to read "Well, it sort of kind of looks as if your balance might possibly be something in the general ballpark of approximately $50 plus or minus, oh, let's say $75... maybe." No. Even if the news is bad, I still want to know exactly how much money I have to work with.
Shouldn't we all want this from our monitoring systems as well - the cold hard facts? So how does one figure out their balance?
Numbers.
Now there seems to be this extremely prevalent notion that audio signals somehow defy analytical measurements - that there is some mysterious ingredient in the wave that cant be detected with anything other than the ears. This is just plain wrong. If you work on a computer look at your music in a wave editor at full zoom. That's it. Amplitude versus time. The only question to be asked is how closely do the pressure fluctuations at your ear resemble the waveform on the screen.
I'm not saying this is a completely simple question. For one thing, the listening environment throws a big wrench into the situation. Still, there are standard measurement environments which give a good representation of real listening rooms.
So are measurements enough? Yes and No. Yes there are measurements which can give you an extremely good picture of the accuracy of a monitoring system. But No, you don't normally (ever) see these measurements on a product data sheet and, therefore, don't have enough information to make an objective evaluation. Frequency response plots are not enough.
So why don't manufacturers provide this data? Sometimes they don't even have the proper equipment to collect the data. And in many cases, they just don't want you to see it. Why? Because especially in the case of speakers the numbers look BAD.
Is there room for subjectivity? Yes, I think so. I think subjectivity can come into play when the numbers don't provide an obvious winner in a comparison. For example, what if two monitors had broadband distortion versus frequency plots like this:
Code:
|*
|*** * * * *
|************ ********** ****
|*****************************
+------------------------------
|*
|**** * **
|******* ********** *********
|*****************************
+------------------------------
The total distortion level is about equal for both, but the frequency distribution is different. In this case, it could come down to subjective opinion about which curve is preferable.
Anyhow, all I'm trying to say is monitor performance is very quantifiable these days. And we should demand more data from the manufacturers than just frequency response.
Numbers! Lets see some Numbers!
