The problem isn't so much bass extension as it is the distribution of resonances -- the second lowest resonance isn't in the bass panel, but the midbass:
The low bass panel is tuned to 68 and 51 Hz, while the midbass panel is tuned to 91, 78, and 64 Hz. So the second-lowest resonance is actually in the midbass panel, while the third lowest is in the bass panel. This means that both drivers should really be active for optimal dipole equalization.
Ah well. Got half of the diffusers mounted with velcro so I can take them off the window and even with only one side mounted properly there was a major improvement in imaging. Then ran out of steam (and velcro) so will have to get the others mounted tomorrow. (Actually not steam, since the radiator is finally fixed.)
