I'm interested in a 5.1 setup consisting of the A/V 3 and 1rs combo but I would prefer a slim low profile center channel like the flat 5 over a 8" tall A/V 3S. Would the flat 5 pair well with an A/V setup or should I be thinking about going with the larger center option? Is there any plans for a flat 3 for an even smaller application? Also, what is the ETA for the center channel LGK design?
