Going old school

Friend of mine asked me about making a 1960s/1970s type of speaker. Big baffle. I need some advice on the woofer. I'm pretty sure the midrange I'll be using is 92.5dB/2.83v, so I'm looking for a highish efficiency woofer. I'd like 8", but not sure those will go deep enough, so I'm considering larger. These may cross around 400hz to the mid. Currently considering Beyma 8P300Fe/N, BMS 10RS300, Eminence 10" Kappa Pro LF, Eminence 12" Kappalite 3012LF, and Eminence Deltalite 2512 II. Any other drivers and considerations I should consider?
Forgot to attach the driver data. Also considering the Dayton PA255.

You have listed more modern type drivers. 12” is a good starting point.
We're just looking for a certain aesthetic, I don't think my friend wants a gigantic box. And I'd prefer modern driver performance. If we do go 12" I'm leaning towards the Eminence 3012LF. I tested the 3012HO years ago and they have a really good motor.

Mattstat's post made me think of the recent GRS replacement for Klipsch. It is 15" and 97db sensitivity. They don't post their usual "recommended box size" and if I remember correctly I put it into WinISD and the box needed to be BIG. Likely won't work for you, but the high sensitivity jumped out at me so I wanted to mention it.

I wanted a sort of old school vibe with at least good performance, so I made pit viper speakers by Paul carmody into an ATC style cabinet, but opted out on using the stock crossover as the response was very not good, I run them active instead. It's a lot of speaker for not much in driver components. It uses the sd315a, dc130 as mid, and d27 tweeter. Idk how big they want it but I bet you could fit that all into a slightly larger than jbl l100 sized boxed.
Theres also thr SB34NRX75-6 for sealed cabs and the SB34NRXL75-8 for ported cabs. Both great paper cone woofers which can be used hugher in cutoff than most 12s and sound clean. Both are over 90dB/W sensitive and the NRXL is closer to 93dB/W. Likely the best semi pro woofer for around $300. Very low distortion and has a 3" VC, uncommon for a driver of this type.
