Thoughts on this 3 way design?

[jtgofish]

I have a pair of Fostex FW305 woofers which are 12 inch -95db /watt sensitivity.I have found this 3 way design in the Madisound library.I was hoping to achieve a medium sensitivity easy to drive speaker and this appears on paper to achieve this.I would have preferred a paper cone midrange but happy to give the Scanspeak treated fibreglass Discovery mid a try as they are not too expensive.The Peerless ring radiator tweeter I am familiar with and have always found it neutral and reasonably detailed.
Any thoughts?
What is the purpose of the two 20 R resistors on the woofer/ A Zoebel network?
There is no recommended baffle width.I am guessing given that the mid and tweeter are estimated to retain close to their natural sensitivity it would need to be reasonably wide.Is this a likely to be a correct assumption?

As far as the 2x20, assuming it’s10 but could be 40.

It could be impedance compensation or it could be damped second order or transitional between first and second. What’s important is that/whether it works 😉

Yes that is not made clear.
