I have just received a pair of El70s. I want to build a floorstander.
I want to try a Derwent or Conistron box.
any sugestions ?

Can you post a few URLs to the speakers and designs you are interested in. Saving us a few minutes on Google will increase the responses I suspect.
I spotted a nice TQWT at RumoH Zelfbouw Luidsprekers

Maybe my question can be: Differences between single and double mouth BVR

I see you beat me to the link 🙂
The double mouth will produce extreme low end with a bit more ease because of the greater coupling area. It also requires that you can listen further away to allow the signal from the 2 mouths to integrate.
The other consideration is of course WAF.

WAF be damned...I say build the double mouthed BVR. Vertial space typically is free 😀
In fact. I have the wood for a pair of these already cut in my garage. I've been meaning to put them together but I've been extremely short on time.
I am in the middle of building some double horns mtm's, a lot better to my ear than any TL I have ever built and i love TLs, worth a look. They are built like the Chang series so it is a short path and easy to build. And yes the air volume is a little large for anything other than a low power tube / gainclone.

I see you have what looks like a 2.5 way in there, what are the drivers and xover? Looking to partner a small tube amp (no bigger than EL84 PP) on modern jazz etc.

its the angle of the pic, they are Dayton RS125 and Vifa DX25TG-05-04 Bi-amp with a XO at 3.3k they are going into my home theater*Or that was the plan till i found how musical they are* along with a dual horn center, TL rears and a tapped or Khorn sub. Running off a set of SE 6550's at about ~15w rms

followed shortly by your own fine self 🙄
well, perhaps the vertical space might be "free", but the listening distance for output of the the 2 mouths and central driver to combine - not always
The place where I sit is 4m (13ft) from the speakers. Is that enough for the double mouth ?
LDSG Section*16 might be handy for any future projects - it's a good way to make sure you're not murdered in the night..... 🙄
That formula may be reviewed to add the form factor. The "visible area" must be part of the formula because a slim tower is better accepted even if the area is the same
