One or Two Shadow Cabinets for Music?

[tripathdude]

I finished the suzy chang cabinets for my a11 pioneer drivers to use as the rear speakers for a 5.1 setup. They sound great especially with phase plugs and puzzlecoated. Would it be better to build two more suzy chang cabinets with one shadow cabinet or two shadow cabinets with the a11 pioneer drivers integrated into the cabinets? I am using two 8 inch cheap $30 Dayton subwoofers for the shadows. Trying to keep this as cost effective as possible. I am using this setup mainly for music.
