michael:

Well my experiences with one EP400 & then a second one are certainly different from yours. They fit my near field listening space perfectly (9' from L & R) plus they fill my rather large room with quality, articulate sound that can also be felt.

As with my HT system downstairs in a similarly shaped room, I believe that this irregular shape contributes to the excellent sound quality that I get from both of my systems.

I suppose that if I wanted to drive my audio system to over 100 Db (unwise & unnecessary for me) then I would seek out something bigger I guess...
