Adding a 2nd center channel?

Interesting idea Nsgarch. This is a variant of a center channel I own from Unity Audio (now Cerious Technologies) that has a rear firing tweeter. All the drivers are angled up on both front and rear, so play with that as well by tilting each speaker.

I see no reason for this except for novelty. Has anyone any reason to believe that any recordings are mixed/mastered for dipole/bipole center speakers?

GOOGLE DTS WEB SITE,THAY SHOW TWO CENTER CHANNEL OR TWO LEFT FRONT AND TWO RIGHT FRONT SPEAKERS.THAY SHOW DIFERENT SPEAKERS ARANGEMENTS FOR HT.

Really? Are you sure they are duplicates and not synthesized?
