I didn't try it myself, this is what Wendell found when he was first experimenting with the DWM/large maggie combination. (I'm using a barrier now on my left woofer panel to bridge a gap caused by a radiator and there is a lot of bass reinforcement since not only does it extend baffle width it gives me the full 6 dB dB of proximity gain, but that isn't sufficiently analogous since it runs about 2/3 the length of a speaker and there are no large gaps between it and the wall.)
IIRC, Wendell was astonished to discover while tweaking the DWM arrangement at an audio show that he was measuring response into the 20's from two speakers that didn't go that low, so when he got back to Magnepan, he conducted some experiments in the listening room at Magnepan and was able to reproduce the phenomenon and modulate the effect by moving the DWM in an arc between the speaker and the wall. However, since the effect was room and setup dependent, they couldn't use it as a specification or selling point.
I don't know why specifically it worked in Christ Martens' and Magnepan's setups but not the ones you tried -- it would be interesting to find out.
