Depends on your definition of "better" :-Dmore powerful and higher xmax Epique is the better one. Correct?
Per specifications it has more bass output capabilities.
Not sure if it can compete in the midrange, though.
But if you install a dedicated midrange driver anyway the better choice is clear (dayton for more output).
I missed those details. A new baffle opens up some options.Yes, the current tweeter does not look good.
Yes, I was also looking at waveguide tweeters. See post 14.
Yes, I will alter the holes. There will be a new thick front panel.

Would you kindly simulate a pair of the 5.5in epiques in 6-12L closed box and help me to compare vs the SB?

I'm missing some details. What is the box volume?
Is mounting the woofer on the side an option?
What if the new baffle was made 1.5" wider than the old, and round over the edges.

The box volume available for the pair of bass drivers (after doubling the walls and deducting driver and bracing displacement) is about 10L.
Side mounting is an option.
Wider new baffle unlikely to help as the walls behind it will remain at narrow distance and would not let a wider driver in.

I plan to do a to-scale drawing (or CAD if I manage to learn it) of the cabinet and drives inside, to make sure everything fits before I buy anything.
If small Daytons do not fit on the front baffle, I will try the SBs in their place or the larger single Dayton sideways at the bottom.

So, nearly identical, right? The drivers have very different Vas, but these curves are so close.
Man, with such of quality builds, why you are not building speaker boxes from scratch??? That is VERY VERY good!
EDIT: nots just good, that is commercial level good!

Well, that is not me. This is a friend of mine helping me. Living in a small flat I do not have any space or proper tools for woodworking, so cannot do it, although I would love to have a go and learn myself. Will pass the compliments!
In the meantime I am learning HFD and WinISD, mentally designing the future speakers, searching where to buy the drivers (not so easy in UK).

Those boxes just for plate amps are already better than many many of the commercial speakers. If friend is this good - just choose the openly available project and let him do his job
I cannot comprehend how this can be. The DA is much more powerful and more than double the xmax. How come it does not beat the SBA on the F3? Or it can, after DSP EQ?Just a little lower F3 with the SBA driver, but maybe the DA fits better in your cabinet.
I am just going through WinISD tutorials and it is eye opening.
One thing I cannot figure out is how to determine the required amp power capability based on driver/performance needs. E.g. how do I know if an amp is powerful enough to work with a particular driver at a particular frequency in my enclosure, with my DSP settings?

I want to design my own. This way I hope to learn more. I also accept I will make a few mistakesThose boxes just for plate amps are already better than many many of the commercial speakers. If friend is this good - just choose the openly available project and let him do his job
With those small drivers you will probably realize soon that it's the drivers' Xmax that will be the limit for a given amp.E.g. how do I know if an amp is powerful enough to work with a particular driver at a particular frequency in my enclosure, with my DSP settings?
Just look at the driver excursion graph in your simulation software, using corresponding amp voltage for a given power. Once the excursion exceeds the specified Xmax you get distortion (and that will be the case at low level for low frequencies).
