Ultimately, if you want a subwoofer (or any speaker for that matter) to have a real kick, snap, hit, insert adjective of choice, you need to ensure that all frequencies it emits, are emitted at the same time and stop at the same time. A complex sound like an explosion, or a drum strike, is composed of lots of frequencies which all start instantaneously. If anomolies in the phase response of the subwoofer cause certain frequencies to start/stop at different points, then the impact of the effect or sound is softened. The measure of how much a transducer slurs it's delivery is it's transient response and it is a distortion of the original signal as serious as any other, but in the time, rather than frequency domain. I'd also note that even the 'harmonizing' CEA 2010 subwoofer measurement standard, fails to take into account this sort of non-linear distortion.
I'm not sure how this maps to something REW measures. Can anyone enlighten me?
Thanks
