The room is 17'-6" x 13'-4" x 8'-0". I have set the speakers on the long wall as recommended by the speaker manufacturer. The tweeters are placed 2'-8" (approx. 1/5 the 13'-4" dim.) out from the front wall and 3'-11" (a min. of 1/3 greater than the front wall) from the side walls. This means they are 9'-8" apart and the speakers are toed at 31 ½ degrees. My head is set 4'-5"(approx. 1/3 the 13'-4" dim.) from the back wall which in turn leaves my ears at 8'-0" from the tweeters. This is a bit more "near field" than what is usual, but the recommended alternative of my head against an acoustic panel on the back wall is not possible in my room.
