Peter's explanation that my horizontal support (which attaches the speaker frame's top to the wall) is effectively transmitting energy away from the MDF frame (a desired thing) hence allowing the mylar panel do its thing with greater accuracy seems right on; I can actually feel the entire support vibrating and right out to its termination at the wall (thereby transforming the entire rear wall into a sheetrock subwoofer panel? Nah).
Makes me wonder if a more rigid support material (thicker wood, metal rod, etc) would not as easily allow an escape for said vibration from the MDF and instead in effect add structural rigidity to the frame, thereby canceling some or much of the desired effect. I'm not going to swap out my custom Home Depot yardsticks to find out if this theory holds any water, especially since I'm still marveling at the improvement this simple tweak has provided. And yes, I have done an A/B listening session with and w/o the easily-detachable supports; overall effectiveness with these in place is readily confirmed.
