Will dipoles still work as they're supposed to (proper reflected sound) if my rear wall is non-existent? The rear of my family room simply opens up into walkspace and the kitchen, with the division between fam. room and kitchen being the peak of cathedral ceiling and a 7" thick beam running along the "seam" Here are family room dimensions: width: 15' 3" length: 13' 3" height: 7' 6" at front wall, rising to 8' 6" at the peak at boundary between fam rom and kitchen. I'm thinking of Paradigm ADPs mounted to my sidewalls above and ro right of listening positions. I'm worried that the dipole driver firing to the rear won't have anything nearby to reflect off of. Is it okay that the rear-directed sound would have to travel another 14 feet to reach the walls of the kitchen? Or rather are the dipoles reflecting off the of the side walls of my theater, which bounces the sound around to the listeners (and thus I'm okay)?
