Three way bookshelf speaker crossover advice

A recent two-way speaker build has turned into a 3-way speaker build due to inheriting some free drivers.

I've made up a crossover on VituixCAD and it looks pretty good to my eye, except that the impedance seems to drop to 3ohms at 900hz.
I'll be powering these speakers via an old Onkyo TX-SR705 which is rated to run 4 ohm speakers according to the manual.
Would this be a problem and does it look like I've missed anything? I'm an amateur at this and some people on this forum have a wealth of knowledge!

Tweeter: Dayton Audio ND25FN
Mid: Tang Band W3 593FS
Bass: Dayton Audio ND105-4

Thanks in advance!
 
Yes, I think I can see a potential problem. You are drawing too hard from the woofer just at the crossover knee. Let that resonance ease a little. Compensate by easing the rolloff of the mid. This should bring other things together, such as the slope of phase.
