Never understand why an Iwata in wood is so expensive for the last 30 years I look at audio world ! the price of a fridge ! Sometimes more expensive than the CD himself (I don't talk about TAD, GOTO....).

I think it's expensive because for many audiophile it's like the end of a road : nothing better, bigger...so a dream have to be expensive !

But don't want a polemic, just want to understand for the same price which is the best sound between horn or planarr, ribbon, ... don't tell me it's a trade off ! I know that, ok each drivers have to be chosen with each others and dictat the final design... i already know that.

I seems to me we are all talking about two things : the final cost and the room integration...

i know your good reputation, but for me at the moment : all this horns are the same, I am simply enable to choose one and don't know if CD is the way to go for me (I don't need high efficienty : if I go with horn it will be for room + sound blend (best design regarding the sound quality in my budget).
Most tricky part is crossover. Try TPL-150H+12p80nd+18lx60v2.

I figure it will take me at least 4.

I would love to get a MakerBot and have fun with it. I don't know much about the properties of the plastic it uses or it's suitability for this use. One could do all kinds of lens and throat shapes. Not cheap though.

I read somewhere that some of the 3D printers use ABS. Avantgarde acoustics use the same stuff in their horns.
I think this is a really good idea. I have tried to find DIY 3D printers that are big enough for some of the bigger horns, but have had no luck yet.

A buddy at work is trying to build one from old HP plotters. If he does, it will be cool - and big.

Just bear in mind that most cheap 3d printers will require a lot of supports on the part to stop it from deforming during the phase change process. These will be difficult to remove while keeping sections and wall thickness correct. Fancier printers nowadays can use water soluble supports which make things massively simpler. I work at a 3d printing company specialising in titanium and nickel super alloys for aerospace r&d and formula 1 mainly. A Formula 1 turbo casing may take 5 days to print but then it's got about the same again in finishing time. They're worth almost £30000 each at the end of it though

Nice! Would be nice to see some pictures eventually

I can understand that they don't make them very big because of homeuse, but is there really any challenge in doing them bigger? What is really deciding the XYZ boundaries? I guess the programming?
