i have trouble implementing the celestion.
if you want resonable efficientie ,say 103db then you lose extension upwards,so then you might aswel make a br box for it.
the problem is with 98 db efficientie compare to the 104 db eff off the selenium ,makes the celestion week, maybe absolete.
i sugest to bild the br for now and buy a few 8 or 6"drivers later on.
 
with 4 dayton in a box you can play crossing 200 herz, to 1000hz(probaply higher)
and well change the selenium from 60 up(wich i think is to low ,80 wil give you that chest punch ,60 hz is where some woofers start to work)

you know how a scoop sounds,they fall of @ 50 hz wo eq

new day 🙂
the s3 aray box is nothing more then a bassreflex box with a hf driver in the middle.
efficientie is about 10 db down on a real horn.= to low.
you need an exponential horn
we could design it with a hf horn in the midlle,then i need dimensions of the hf horn to compensate the mouth area.
 
i discovered a flaw in the dayton 6" ts parameters,result is lower output in the 700 to 1000 hz area😡
the cheaper dayton 6" work better but you deff need 4 per box.
hf in the horn wil only work if we now what horn were using,so you better make a seperate hf box for that.
