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?

Pretty challenging first post at diyaudio...
Basically OK choices, just you just need to learn Vituixcad v2 and measurements!

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.
