I found myself in a similar situation a couple of years ago, after moving my system into a newly-expanded Great Room (30'x30'x12'). I made the correct decision for my situation by upsizing my speakers to Tyler Woodmeres. What I noticed was a much larger midrange and bass reinforcement that I think could only come from larger drivers in a larger cabinet. Now, the entire room is filled with music, and it overflows nicely into adjacent open spaces. Tyler still makes the Woodmeres, although they are not currently featured on his website. Good luck.
