I see,
Im keen to have them running the other way, for aesthetic reasons, and allows more nesting of components and so less material wastage.
Are those yours?

damn, i have to download the pics and upload them the normal way...
StudioAu, yes they are mine, next weekend i will be cutting the front ring, and the rest of the back rings, then a business trip and after that probably turning the outher shape on a lathe...

I am using Fostex 168EZ Sigma drivers, XO will be active, probably miniDSP, I need to build some SET amp for them, the bottom will be probably 15" Pro driver or very 12" Pro driver, not decided yet...
I did had them running in the enclosures, and I can tell, there was no need for a sub in about 15m2 room, no booming, no shouting, I was very surprised how it turnd out sonic wise....
Even with a lot of EQ and high volume, the drivers were not distorting even with high excursions...
Danny
P.S.: can I send the pics to someone to upload for others to see? using tablet now and i cant upload them, can email them tough...

Email sent. I don't mean to highjack your thread, but I thought some ideas might be helpfull for you.

looking at your idea with fishtype laminating oposed to ring like mine, i think you will need perhaps more material then me, you need to have enough material to be able to turn them on a lathe to round shape. I used two sheet of ply 100x50cm, when i cut the big rings, i ws able to fit smaller one inside it, with some even three tings from one cut.
how wil you achieve the inside shape? the back funnel has same diameter as front speaker cutout... at least in my case. I thought of rounding of the inside, or sand it by hand or something to have smoot surface, but somehow dont know how to do it, the biggest step is where the funnel meets the sphere shape, about 18mm a side.

I have adapted the design and split the fish shapes down the middle. So with a router or CNC I will make one half of a 'wishbone' this will allow them to be nestled really close.
I was hoping that the stepped nature of the fish shapes would help with diffraction on the inside, and actually be beneficial. I would either sand or route the hard edges off.
Might be easier to fill the gaps, if you want it smooth, a thin layer of clay or something similar?

I will.
These are my goal for the next few years...Active, large horns, big subs. Solid wood, heavy cabinets.
I haven't seen anyone using the Mark Audio range for front horns, anyone else?

An externally hosted image should be here but it was not working when we last tested it.
perhaps only one horn, from 150Hz up, i have seen one, although expensive, in germany, about 700 euro/piece
Then you can make a really good PA sub to go with it me thinks.....
Actually I want somethng like this too, in my fathers spare room.... NO WAF 😀

I have a pair of MA CHP-70's on there way to me.
Hoping to build a pair of frugal horns mk3. Nice to have a big stockpile of drivers to play with...
