Hello everyone!
Some time ago, I built a pair of Fostex Speakers (picture below). The drivers are FF165WK and FT17H super horn tweeter and the design is bass reflex following the FF165WK bass reflex enclosure recommendations.

Now I want to build the center speaker (and in a near future, the two back speakers to complete the 5.1 sound for my living room).
I've never built a center speaker with two drivers, so I need some recommendations. For the center speaker, I have two FF125WK and another FT17H.

Shold I double the volume recomendations of the FF125WK or there is a more complex calculation for bass reflex with two speakers in series?
Thanks 😀

There are substantial reasons why you don’t want a side-by-side MTM.
And given the FT17 crosses as high as it does, the combo does not make for even a good vertical MTM.
The FF165wk doesn’t really need a tweeter, but it does from having some of its rough edges smoother off.
Here is the FF165wk centre channel miniOnken that accompanies teh FHXL.

Greets!
To reiterate, not a good plan unless you design based on polar response and IME cross fired on a bifurcated baffle based on desired coverage angle, which in turn makes it pretty much limited to that one HT layout. 🙁
Right 2x net Vb, 2x vents.

Yes, marketing department over the engineers. Given the oft-needed centre with a low height, and the penchant for 2-ways, the tweeter beside the woofer would work better but look strange. so mtm-h. better, IMO, to just use a FR,

Bit a sound bar is typically either small FRs or WAW and rarely more than one midTweeter per channel.

Right, not just what Dr. Geddes said either, the tweeters should be at 2/3 screen height where a film's closeup head shots are.
That said, Ga. Tech's Dr.Patronis' cinema sound system for unperforated screens patent was used on some large trade show expos to good effect and performed better overall than the below screen floorstanders on a long gone friend's front projected HT and currently doing fine in stereo angled down/toe'd in above my big screen TV using ancient RS Minimus.
