There are basically three areas where linear-phase loudspeakers differ from minimum-phase loudspeakers.
1. Linear-phase speakers provide more accurate spatial information, rather than timbral. Tonal balance is the same for both loudspeaker types. This is where the tests are falling apart, because listeners are looking for tonal differences, rather than subtle spatial clues – sharper image, better located soloists, stage depth. It’s subtle, but it is there.
2. Identical phase response for all loudspeaker in the system. The phase response in correctly equalized multi-channel linear-phase system is 0deg in every loudspeaker. Therefore it immediately satisfies AESTD1001.1.01-10 for phase accuracy and transient fidelity to perfection. The measurements of linear-phase loudspeaker are presented on my website, and comments on AESTD1001.1.01-10 are presented in -

3. Tighter bass. Even Dr. Floyd Toole quoted other researchers (Craven and Gerzon) on this subject on page 420. The most obvious difference is the tighter bass. I have conducted extensive tests on this subject -
