I would try a lower cutoff than 3.5kHz. I know that is what Eminence specs for the APT but that is intended professional utilization.

IIRC Eminence's old 3K5 passive network had a real xover ~2K8, their current recommended CX-net is 2mH/10uF, 0.35mH/3.3uF - not sure where that one effectively crosses - believe its spec. at 2K5
