Regarding measuring speakers in an anechoic chamber, a speaker’s job is to reproduce the sound of the waveform accurately. An anechoic chamber (or software that simulates a chamber) is needed to measure the direct sound that is coming from the loudspeaker without any interference from room reflections. While it is true that loudspeakers will eventually be listened to in a room which will affect the sound, the speaker’s job still remains exactly the same; to accurately reproduce the waveform. The best way to determine if the speaker is doing this is to measure it independently in a chamber.
If you want to deal with solving room acoustics problems you need to address the room itself via room treatments and modifications rather than by attempting to alter the waveform played through the loudspeakers- excepting the extreme low frequencies. The human ear/brain is very capable of recognizing when the direct sound coming from the loudspeakers of say a piano is altered or wrong. This distortion of the waveform in an attempt to pre-correct for room problems is simply going to compound errors rather than accomplish actual correction.
Getting back to Richard Hardesty’s critique of the Wilson speakers and how it relates to the current discussion of speaker measurements. How can a speaker be considered accurate when it completely distorts the waveform’s time and phase response. If the tweeter is “pushing” while the midrange driver is “pulling”, something is very wrong. If the instrument you are listening to is in a frequency range that needs to be handled by both drivers simultaneously (e.g. a piano), there will be a lack of coherence in the presentation. Even with instruments whos fundamental frequencies lie in the midrange, the upper harmonic content extends well into the treble (e.g. with a trumpet). In this case the speaker will be “spitting” and “sucking” at the very same time.
