It varies depending on room construction & other positioning considerations. 1ft out should work in many situations, once you've got them optimally damped.
My house is easy...50hz suck-out LOL!!!
That's why I rarely care about anything below that...too much work to deal with...as long as the bass doesn't over take the top end but compliments it...all is good 🙂

I managed to get a really good deal on a Woden Victor cabinet and a pair of FE168e∑ drivers. Any particular issues with using the sigma drivers with these? More/less stuffing?
Christmas gift 2020 for my parents .....
A set of Victor Fe166
To be continued 🙂
Any Bsc recommandation ? ( i'm ordering the hardware .... )

The back loaded horn contributes gain at LF to mitigate the need for BSC. Indeed, depending on room placement and amplifier (do the parents have a high output impedance amp to drive them?) you may actually need antiBSC (ie add some damping).

Absolutely. One of the advantages of a back-horn is that you can compensate for step loss via broadband gain.
I learned from the best (you know who you are 😉 ): if enough is sufficient, then too much is just right... 😀

I've started the enclusure
About the amp , it will be a SA300 SMSL ( they are 70+ YO and it's a present more than a perfect audio set up as they won't notice the not perfect set up with non expert 70+ years ears )
In fact they were totally in love with the FH3 Fe126En i made for my son and nearly asked ( shy attitude ... ) so ....
SMSL SA300 has a few corrections inboard , so when delivered at their home , i'll get Rew and see if in need any other correction
Beech 18mm pannels are in the cutting process at the moment , speakers and amp arrive this week ( prefered to plywood for cosmetic reasons ( my mother 🙂 )
All the hardware received today
Let's go 😎
Pictures of the construction as requiered will follow

The first cabinet will be closed today , the second one within two or three days , i plan to make transition on all te internal corners of the rear horn , worth the effort or use less ?

I suspected as much. Doing that will degrade the horn performance. At each one of those 180° bend there is a bit of an expansion. This acts as a low pass filter.
If you put those in you will get to much HF out the mouth which will directly affect the response in the about 300-600 Hz range, and not in a good way.
