Thanks for the feedback all, I'll run them for a couple of weeks before I do anything.
In the mean time I've been looking at the Voigt pipe design, i would be interested to hear any first-hand experience, they look fairly straight forward to build and from what I've read give very acceptable bass

Lowther with some correction sound very good 👍
If you support with a good subwoofer it will be very good.
I know how BLH works and it needs bass support.
I have also made open baffle system with Lowther PM6A and it sounds very good with a notch filter to tame the peak (Lowther shout).
Here with a fast 15 inch PA sub and Tone Tubby 12» Alnico from 70-300 Hz.
So my reccomandations are:
Notch filter, subwoofer and also to test a supertweeter around 10000 hz with ONLY ONE capasitor in order to not mess with the phase.

Mass Loading = restricted terminus.
A folded ML-Voigt for the FE108e∑.
Nandape has done a bunch of those.
Here is one we did for 4 Peerless 830870. Here the restricted terminus is just the thickness of the build material. It has a midTL on the front and we had to contort the shape of the Voigt.
And an example of a Woden Festival ML-Voigt

Hi, if you want deep bass out of the lowther, build the ” Big Fun Horn”. I have a pair of EX3 in them. They are large tho and will need room. I use about 8 watt VFET class A amp with them. I have tried differrent enclosure but the BFG puts out the deepest bass. I don’t need to use a sub with them.

yes that is the one. Dave is correct about placing in the corners of the room to get max. bass. Mine is away from the corner but against the back wall and still put out low bass.
I already get some really good bass with a classical sub with corner placement letting the driver face into the corner.
It's clear the better a horn is coupled to the corner, the better.
Dreaming of having openings in the wall in the corner to really put my box into the corner when using a horn.
The big fun horn is elaborated.

If I interpreted Freddy's numbers right (I changed conical to parabolic and used an optimistic 0.5 pi and set "path" to a rough estimate, no filling) this should show the response. A more experienced modeller could probably use their talents to adjust things to have it perform better. This can be imported into hornresp to play further with. It doesn't include the absorber chamber present in the Jericho's although one can be simulated in hornresp using the input wizard. In Talaert's thread on the newish Jericho, Dr Boar posted where the chamber is effective--reducing peak around 180hz IIRC.
