Snell Type D Positioning Question

Hi, I just picked up a pair of Snell D type speakers for $50.00. Need some advice. As background,my room is 17x10 that adjoins a smaller 10x10 room. No wall separates the rooms. I use the larger room with the equip across the long wall. My chair sits into the larger room just ahead of the boundry separating the rooms. I do this because there is a post that obstructs my listening.
I cannot find a manual online, can anyone tell me how these should be set up so I have a start point to fine time the speaker position. They have a tweeter on the rear so I'm thinking that they need to be out from the wall a ways. And do they like to be set in a equal triangle with my chair, or do they like to be spread further apart toward the side walls. Toe-in required? Any advice you can provide would be greatly appreciated. I will be running the Snell's with an Odyssey Stratos amp and Odyssey Canedela pre-amp. Thanks much, Dave
