The stereophile frequency graph in question was for Druid mk2....... Using an different tweeter and FRD to the MK4 that won all the awards. Druid needs a 10mm gap at the base to load the cabinet. Standard testing calls for the speaker to be suspended in the test chamber.
Omen and Druid Mk4/08 share the same tweeter and FRD with a different phase Plug. The difference being that Griewe loading in Omen is achieved using a foam pyramid as with Superfly and Essence not a gap.
The Zu FRDs are sourced from Eminence.......The largest pro speaker manufacturer..... Most live music you hear use Marshall and Fender stacks filled with paper cone Eminence drivers. These speakers are specifically design to be abused...... Home audio speakers are not.
