That peak isn't a flaw, it's intentional. Planar woofers are intentionally underdamped to compensate for 6 dB/octave dipole cancellation. They have to be or they wouldn't have any bass! This is what the response of an uncorrected dipole loudspeaker looks like:The ideal woofer response curve, if you're after maximally flat bass, is the precise inverse of the rolloff. This is true whether the speaker is a planar or a dynamic. Carver for example underdamped the dynamic woofers in his Carver Amazing dipoles. Linkwitz uses electronic equalization in his H-frame dynamic dipole sub, but that puts very heavy demands on the amplifier. He has an interesting analysis on his site.
