I think what Ivan is saying is that these are subjective impressions.
To one person, x speaker is laid back, and yet to another who's used to listening to very warm speakers, said x speaker is might seem forward or bright!
Then there's the way the speaker interacts with the room and the way the room interacts with the speaker.
That said, nothing wrong with looking at measurements at all!
Try to find speakers that are at least +/- 2db between 200hz to 10khz, with no major peaks below or above that range either.
Try to avoid speakers with response swings up or down by 3db or more. this usually indicates over or underemphasis of that region.
Most 1st and 3rd party measurements lack sufficient resolution and may not even be accurate measurements due to methodology (few measurements are actually taken in real anechoic chambers). Compare this:
Obviously speaker 2 is better right?! Nope! These are the same measurement
, one is just made to look better on the graph between smoothing and scale.
The above is all frequency response on ONE axis - normally 0 degrees (right in front of the speaker). What we hear in rooms is not frequency response on one axis, it is sound power response - sound radiated into the room. So the speaker also needs smooth off-axis response out as far as perhaps 60-70 degrees horizontally, and vertically a listening window of 15 degrees. The room reflects sound back at you, so that sound should itself be balanced. If too much tweeter energy is reflected relative to the rest of the speaker, then a speaker that measures FLAT may sound BRIGHT!!!
If the off axis
response looks like this:
the speaker is probably not as good as a speaker whose off axis response looks like this:
Not included in the above, is level dependant stuff. Some speakers sound good at low SPLs, but start to sound poor as SPL rises.
