For small experimental DIY projects, if you know anyone with a printer you might be able to 3D print cabinets. Plastic is probably not the ideal material to be using, but you can use materials which are wood bound with plastic.
I've got a small printer and it is capable of building up to the size of an OSMT cabinet. For me, it's far easier to model up in software and let a machine do it, than get access to a woodshop.
Well, he's cerainly added a number of enclosure links, as new ones are developed. The data sheet has always had the spec. on it & the data was on the site also -albeit admittedly you have to scroll down the screen a bit.
Shouldn't be any lower than it would be in a 2-way, if you select your crossover points & design the filter well. They're both going to be a nominal 4ohm through a portion of the BW, and as noted, that shouldn't trouble almost any amplifier these days. If it does, it's probably worth replacing. Certainly nothing in my inventory would so much as bat an eye at it, including a 25 year old entry level Rotel integrated (first version of the RA931) which would cost peanuts to buy second hand.
That said, I'm not sure I'd bother making a 3 way with a CHN-50. Since it makes a good mid-tweeter, I'd just use a low-filter 2-way like the pioneers did. That's actually more or less what I would have liked to do with the MA-Sota commercial gear (the CHN50 is closely related to the Sota 5 mid-tweeter), but I wasn't able to due to cost & space considerations over the components.
@ David Morison.
You are right, this woodwork facility is in the GuildHall, which is a huge central Town Hall type building in Portsmouth UK.
I must investigate.

Looks fun. Thank you.
Sort those CHN-50's out too. I have old cabinets I can adapt.

Interim update on this. Turns out that my god-daughter is already soldering electronics kits together. So an Overnight Sensations or similar kit should be right up her alley- a step beyond lego, but nowhere near the realm of acoustics and electronics design, so it should be about right.
Her father works on his his own boat, so the pre-fabricated cabinet should be well within capabilities (it's literally gluing, sanding and clamping then a bit of paint, very easy.)
Now I just have to figure out the optimal source/delivery method. I'll compare the EU source to the US ones again. Thanks everyone.

@wimbledon If you have someone who works on boats and someone handy with a soldering iron then I don't think you need to go for precut cabinets so long as you stick to design with standard rectangular boxes. There are a number of UK sellers that will provide precut ply or mdf so all you have to do is provide a cut list (or enter on the website) and thy send you it all done, then as you say just glkue, clap and paint. So, if you look for project with drawings, a crossover diagram (parts can be got from Falcon, Willy or Hificollective in the UK) and frequency plots then you will be good to go.
, do you guys know if it's still possible to buy IPL kits and where? Thanks in advance, Alex
