Any chance of repositioning the speakers parallel to the high ceiling short wall and your listening position more toward the 8 ft high short wall. The room appears to offer a very interesting listening enviroment but I think your current layout is not making optimal use of it. With a more symmetric layout (so that the ceiling height above each speaker is the same)you should get more consistent bass response with the speakers.
Bass traps/room treatments
Has anyone tried echobusters bass traps, or the ceiling corner bass traps? I have a fairly large room (13x25)with my SC-IV/a's on the long wall, with a high ceiling sloping left to right (16'down to 8'). I've been draping tapestry
from the ceiling and have noticed improved bass response (weird) ...it's really got me thinking about purpose built taming devices.....when I stand behind my speaker in the corner, it's super boomy. The bass in my room is not boomy, it just doesn't have quite the impact and extension you'd expect from dual 10' woofs in each speaker, which makes me think I've got some deflection problems.
