Shadorne says: """In essence a biploar is like having a virtual second set of speakers placed behind your rear wall at the same distance as your speakers are from the rear wall => you actually hear four speakers ...really I am serious!! Therefore toe in or out will do very different things compared to a conventional speaker.""" Yes, indeed, I have bi-polar speakers too (Superslim 1800se, from www.ambiencespeakers.com.au) I love that Ribbon Sound but at the same time the back firing wave has to be neutralized. I am getting a few GIK 4" thick Acoustic Panels. I think prety much all bi-polars must deal with the same problem either taking them away from the back walls (as far as possible) or absorbing those waves with some kind of Room Acoustic Treatment.

Speaker Positioning
I have a very small listening room. My Mirage bi polar M5's are about 7 feet apart and my head is about 7 feet from them when I'm in my listening chair. Should I toe them in and point towards the chair or point them straight ahead?
