RE: Subwoofer with ESL 63

Interesting, hadn't considered the effect of the unsupported panels on the side.
Also, not only will a dipole woofer trigger fewer room modes, the ratio of direct/reflected sound will be the same as with the line source.
However, the SPL drop-off will still be inverse square since they're point sources, and won't match the 1/R falloff of a line source. Depending on crossover frequency you don't need too many woofers to create a line source, if they're spread out. Two per wavelength, taking into account floor reflections. And if you sit the same distance from the rear wall as the woofers are from the front, the first rear wall bass reflection will be cancelled -- I tried that back when I had 1-D's and it really did work.
