Seating distance to Magnepan 3.6r's?


I'm moving from my current living conditions to a new apartment. The main room (living room and listening room) is 17 feet wide by 26 feet long with 10 foot ceilings. My questions is: the Maggie's will be approximately 4 to 5 feet from the front wall, what is a proper listening distance, how far back should one's listening chair be?
Thanks for all your comments.

"Sogood51, Won't 25% out in the room create MORE bass then 33% out in the room?"

Exactly...and thats the point. Somewhere between the 1/4-1/3 point you will find a nice balance.

Nothing is exact, and you don't know going in, if you need "more bass"...or "less bass" until you measure and listen...it's truly a game of inches.

The CARDAS setup guide, is simply an attempt to reduce peaks and nulls in any given room....it won't work in every room.

Funny, I didn't know about the CARDAS setup guide, when I set my speakers up years back (maybe it didn't exist?)

I used variations of the 1/3-1/4 rule, until I was blue in the face from moving 150 lbs around for hours on end. I did finally find a great spot, where everything sounded outstanding.

That spot, it turns out a few years latter...was within inches of the CARDAS location. (I could have saved myself a lot of time, and work).

Regardless of how you set them up...all rooms are different, some amount of tweaking by ear, is always needed...even,if for no other reason than taste.

My three front MG1.6 fill the room with sound that is remarkably uniform throughout the room. Volume and soundstage are unaffected as you move around the room. The Maggies are usually about 4 feet out when in serious use, and I push them back when not in use. The room is very irrugular in shape and quite large with stairway and large hall openings, and perhaps this is why my speaker placement is non-critical.

Over many years of playing around with Maggies I have noted some interesting things about placement.

Ideal results are obtained in a very large room (like a gym) with high ceiling with the Maggies about 40% of the way into the room (almost in the center) and best of all hung from the ceiling.

Sit directly in between two Maggies, so that you are listening "edge on". Sounds like a headset. There has also been some discussion of an unconventional placement with the edges directed towards the listener and the front and back waves reflected (Bose-like) from the front and side walls.

Outdoors they are useless.
As a footnote to all this, when I first started with the Maggies, I had an 8 foot ceiling and this lasted for 20 years...then I moved into a building where the living room had a cathedral ceiling...When I put the system back together and turned it on...WOW... they sounded the best ever...even before the placement struggle began.

I attribute all this to a diminished or minimal sound wave coming off the ceiling. In the new room as well as the original room allI had was the audio equipment, two chairs and a grand piano which the speakers face but at the other side of the room.Both rooms approx 12 by 20.

I would be interested in your (or anybodies) comments aabout htis experiance.
