Yes the idea is that even though they do not go much lower the woofer placement close to a boundary reinforces low bass and the smoothing affect of multiple woofers makes for a much better frequency response in the lower octaves.

I can understand the reasoning as one of the shortcomings of my 1.7's is that sometimes the low end seems a bit thin. But what about the frequencies below 40hz? I have a lot of music that utilizes that "last" octave.
I guess I need to listen before judging, but I remain skeptical that the Magnepan woofers will be a complete solution.
