Default Xover to filter woofer SB 23NRSX45-8

I'm finishing my 3 way project I only need to do the xover for the woofer SB Acoustic SB 23NRSX45-8 here

SB 8 inch woofer sounds great on its own.

the advice is Low Pass = Linkwitz Riley 24db/octave at 300hz.

Link to previous 2 way Help for 3 or 4 way loudspeaker

What is the box volume? I have the same woofers and begin to make boxes soon. My project is very similar to yours.

I got a quad of the 12-ohm version when they were on sale. Two of these wil fit very nicely in a 45-50 litre closed enclosure.

I'm skipping on some of the design work, and shamlessly steal the 49 litre enclosure from the David/Jericho watt/puppy clone, and just omit the bass reflex tube...

For bass reflex, this cabinet should do nicely with one of these woofers...
