I ask, could two mid-woofers with the same impedance and size need a different box volume for a two-way?
Yes. If they have different Thiele-Small Parameters then they will need a different sized box.
Btw, bose had partition for each nine individual drivers in their 901 model. Guess they expected differences.
They may have been looking for an excuse to brace the cabinet.. or perhaps had some idea to do with breaking up modes.
yes, same diameter different brands. I was asking because at the moment I don't have the equipment to evaluate them and these two woofers that I have from Wharfedale I was thinking of using them in the Ls 3/5a box to make a pair of desktop speakers, with a tube amp. just to see what I can do...
It doesn't make much sense to even use two if they are different sensitivity, or other certain things.
What is the property you are expecting to enhance by using two instead of one? We could consider your options.

The only way I would use two different midbass drivers would be 2.5 way. Definitely not mtm.
Even size is the same, different brands mean different parameters.
let me explain better: having two wharfedale woofers and two tweeters, I was thinking of using one of my many LS 3/5a boxes to make the two desktop / pc workstation speakers. nothing stops you from trying, maybe the volume moves them well.
Ok, so two woofers just because. We've all done that 😉 You may not notice any of the below points but for those who know...
If they have different bass resonance properties they may fight and you could lose some bass.
If one woofer is generally louder than the other, you may not hear the other significantly enough to really notice an increase in level.
If they are both played at the upper cross, they may reduce output through directivity and not match well with the tweeter.

sorry, I have to explain myself better 🙂
I don't want to use a double woofer, but use the Warfedale instead of the classic B110 of the LS 3/5a. sorry my english, I'm a web-developer and I only know web design stuff.

I reckon you should supply details of your two Wharfedale woofers.
Do they have identification numbers on their labels? Can you say from which Wharfedale speaker model each was removed?
And perhaps some photos of the woofers would be helpful.

yes, but no pics at the moment, but they are the woofer and tweeter of the central Diamond 8 which also sounds good when used as a single speaker.
You have two identical woofers from the Diamond 8 centre speaker shown below?
If Galu knows them then we'll see how they go in that box, but even if not I think you should still try them. Closed box response is somewhat forgiving. They may be light on bass or heavy or just right.
it's true. in fact the LS 3/5a is in a closed box of a few liters, while the diamond is a reflex on the two woofers. let's see... as soon as I have 10 minutes I'll dismantle the Wharfedale and see what the reflex is like inside.
I'm afraid I don't know any details of those centre speaker mid/woofers.
How they would perform individually in an LS3/5A sized sealed enclosure would be a case of suck it and see.

no problem 🙂
yes, i just have to redo the front panel because the fixing holes don't match up, once the components are fixed to the front and the crossover that is in the diamond, the test is quickly done. the doubt i had regarding the diversity of the components is and was well founded. in case the closed box is not the right place, i will make another one with the addition of the reflex. it will be a great achievement if i get to have a sound as close as possible to the Monitor Audio silver RS1 that work in reflex and have a more balanced sound than the B&W Cm1 that in my opinion the tweeter is too invasive.
