Phase-corrected Fostex FE166En crossover for a Fountek NeoCD3.5H horn-loaded ribbon tweeter with a Bessel 18dB/oct slope. Tacked on a Zobel to counteract the impedance rise of the Fostex full-range driver. I might re-check the (Le) of the woofer to confirm, as it seems quite low to have such a high impedance rise.
