I think one woofer (with one inductor+rc maybe) could work, but I don't know what you have in mind. In this case I would test the (1x) SB ACOUSTICS for sub and adjust variant internal R in the L1 coil for the main driver.
If for one driver as above (30,5cm x 34cm ext.) for 70 L.
Height in cm: 95, Width in cm: 30.5, Depth in cm: 34, thickness in cm: 2.2

You can use any vol. calculator.

The thicknes of the wood is 2 cm, the rest of measures are:

High 36 cm
Top 13,5 cm width

The internal structure is Matrix type, attached pics, the left side pic is the tweeter hole so the loudspeaker have three braces internally all with holes.

I'm sorry for a lot of questions: what about the BR, front, rear, diameter hole, depth of tube, position, etc? link to calculate & see the best position, etc?

Yes a lot confusing, all questions are about the bass reflex hole:

-Where to do the hole: front or rear
-Position of the hole: near the loudspeaker of two ways, in middle or near the soil. Centered or in the interior side or in the exterior of the box.
-Diameter of hole
-Length of the pipe to tune
-Etc.

Your help is really appreciated.

If your speakers will be close to a wall with their backs a port on the rear is out of the question straight away.

The diameter (or area) and length of the port should be given to you by whatever software you use to design the speakers. It will depend on the particular driver and the tuning you choose.

why BR ?

I would suggest acoustic valve(apperiodic), if you want your top/mid 'vented'
