re: low xover 1st order - do you have notch filter there too to limit out of band modulation? I don't like to see cones move at allDefinitely. On the ILB's, I once seriesed up jumpers with the 288G shunt LC notch networks and listened to them at my typical levels (maybe 2W average total LF & HF). I estimate that w/o the LC shunt in front of the 288G VC, the effective corner was about 400 hz straight first order, where the horn was starting to unload, and with them in, about 550 hz, but with a big notch at 150hz). After about 5 seconds w/o the LC shunt, I was scrambling to put them in to remove the muddling the out of band excursion was causing the 288's. You get a little extra phase angle at xover w/ the notch, but a lot less than 2nd order - much preferable, IMO to tweak tonality a bit rather than reverse polarity to cancel tonality killing notch for similar out of band rejection.
