Dipole panels have the same problem with bass as open baffle cone speakers. The technology is less relevant than basic acoutics. As an experiment, try 1' deep plywood "U-frames" on panel speakers.
Why do planars have poor bass extension?
I've been wondering about this. Is it because the excursion is limited because of the tension of the diaphragm & low BL limits its excursion?
On a related note, what techniques do companies like Magnepan use to get more bass out of their low-frequency drivers? Do they put bigger magnets in the grid than would be feasible for the midrange? Heavier diaphragms?
Finally if anyone knows a good reference for learning about the TS parameters of planars and if/how such calculations differ from dynamic speakers, that would be awesome!
Thanks all!
