My dimensions are 14W x 22L x 7.5H I have the Prodigy positioned along the short wall because I have no choice. As you might be well aware, Logans are very placement sensitive. The sound especially imaging l>r could be better because I've heard it better in a bigger room. Any size Logans should be fine as long as you position the speaker along the longer length of the room because the Logans need to be a good 7 or 8ft apart, far away from the side walls. Happy hunting!!
