As you are well aware, the one advantage of a 1st order series XO is that the output curve (electrical) remains flat regardless of changes in the impedances of the drivers. This might be an advantage for cone drivers (woofers) that heat up and change impedance with use. Not so much for the planar since the heat is rapidly dispersed. Also, if the sensitivities of the drivers are the same then one gets a very nice flat acoustic output curve. OTOH it is highly unlikely that this condition is met so this advantage is somewhat moot and by varying the 3db points of the LP and HP filters, it may be possible for a parallel xo to compensate for acoustic "bumps". I vote for the parallel configuration.
If Magnepan had stuck with the parallel configuration, biwiring and biamping would be a lot easier for the DIYer.
