Baffles and low order loudspeaker designs such as open back, closed back should send to tea everything else

The best should be the baffle are it has the least low cutoff slope, best phase response which is critical for transient response.


This means detail.


Accuracy.


Then still acceptable should be the closed enclosure design. Greater slope but still relatively gentle. No wander the Thriller - Michael Jackson was mixed by Swedien and Jones on closed back unvented Auratone 5C monitoring speakers.


One drive unit speakers may send everything else to tea as well as they have the least phase errors (no multiple driver time delay etc).
