SB Satori and Seas coaxial floorstander

Hello everybody,
I am currently trying to design my first DIY speaker, a 3-way 10/12”- 5.5”- 1”. I bought seas seas c16n001/f for Midrange and tweeter driver. Now, I hesitate between 2 options SB29NRX75-6 or WO24P-8. cabinet will be similar to this project below with woofer volume from 60l to 65l
I would greatly appreciate if you have any advice on other woofer drivers under 250$ to be used, as this is the biggest question mark for me before I pull the trigger.
Does any one of you has any suitable crossover suggestion for this config?

A quick calculation on Qts, Fs and VAS for both woofers with factory specs shows (required enclosure and F3)

WO24P-8 - 81L and 24Hz
SB29NRX75-8 - 74L and 27Hz

Both the above vented.

So it depends whether lowest F3 or smaller box suits you best.

The SB29 potentially has higher SPL potential (more xmax, bigger Sd).

I cannot get comparative bass distortion performance between the 2 - but guessing WO24P-8 will win here.

Download WinISD and have a play.

You need to list your priorities and choose the woofer based on those ..... w.g. Lowest F3? smallest box? lowest distortion? price/performance? Cabinet width? etc...

Both drivers have the same sensitivity - and will match the nominal 85dB of the seas driver. You'll end up with a net 83 - 84dB sensitive speaker - so be prepared to have some amplifier watts (recommend 200+) to give the dynamic headroom you need. PS: I am running an all seas 3 way - around 84dB, min impedance 4.1Ohms on a 350w amplifier and this is sufficient.
 
I would use the WO24P because it has a low inductance motor and modest 44g Mms which produces smooth detailed bass up to 1kHz.
======
If you design/build a separate cabinet for the WO24P you can later build a second tweeter-midrange top to compare with the coaxial seas c16n001/f. A separate woofer cabinet also allows time alignment.
=========
You do not want a slanted front baffle with the c16n001/f coaxial mid-tweet driver. A slanted baffle is sometimes used to help time align a deep midrange cone with a tweeter so the two waves arrive simultaneously at one listener distance.
