8mm MDF, veneered on both faces, last I checked.
As far as the crossover goes, the majority of current Harbeth models run MKT film caps from Suntan in Hong Kong (you can see them in the image Steve posted), although the 40th Anniversary models, if memory serves, have MKPs produced for them by ClarityCap. Alan follows the BBC mantra of even axial response as the dominant objective, with the same bitumen damped thin-wall construction approach the BBC research department under Harwood focused on.

Is it arrived ? How does it sound ?
I don't think they have arrived yet. But I am excited too.
I scarcely expect them to be what we Brits might call: "A Damp Squib."
I loved my time with the SHL5plus. incredibly transparent mids and very good bass extension, they really go down to 30hz.
imaging is not their forte. its still just a 8 inch woofer so the bass wont shake your body like a 12" let alone a 15". and the treble was to my ears too bright.
but that midrange... probably the most transparent and open window iver ever heard.
but at the end of the day, nothing replace a 12"or 15" for bass, and im not a fan of metal tweeters.
I will buy a pair of Harbeth 40.2 one day

excuse my OT
So you are not yet satisfied with the speakers you have now ? - I notice from your sig that you have the Altec604 - is this the original driver or the more refined GPA unit ?
This thing should let us think twice. The main driver is going perhaps till 1500 hz and it's very transparent. Like an ESL which sweet spot is also difficult ?!
Now imagine the polycone driver in a modern enclosure like a Kef Blade or a Vivid !
Now the hybrid ESL have often a XO in the 200 - 500 hz area and I read testimonials some liked more the Haberth polycone presentation than an ESL diagphragm ! Maybe a filter in that area is not such a good thing ! And I wonder about the XO cutoffs choice of the Haberth flagship with its two plymer cones...Well it's OT !

Well, it's a flippin' miracle that some loudspeakers conceived by Alan Shaw in Sussex, England are currently rocking up to your door in the Windy City of Chicago, Illinois!
Arizona to Chicago is quite a Road Movie in itself. And who did it better than Harry Dean-Stanton?
We have no idea who the Truck Driver might pick up on the way! Me and Bobby Mc.Gee
Current 2 metre social distancing, naturally, considered. TBH, I think Waylon, Johnny, Willie and Kris would buy these speakers. But let's wait.

It's clearly a good driver of its type in terms of its FR. It is not likely to significantly benefit from a differently shaped box, except in terms of diffraction, which does not appear to be a major issue in the original. The enclosure resonances are high Q, so less likely to be excited on a varying signal, although in theory either some additional bracing or additional damping may have been beneficial. The
Probably do (almost certainly) but a matter of opinion.
Nothing wrong with it taken independently, but if you cross an ESL to a moving coil in that BW you risk a significant shift in polar behaviour / characteristics. This is a matter that varies on a case by case basis depending on design details.
We have touchdown! Harbeth porn tomorrow, I put off shopping all day to make sure I was here to sign for them... I have to do some marketing, and then a haircut.. looking like damn wookiee!
Then it's home for some fine Irish refreshments and possible the first listen... I might just sit here drinking single malt and admiring them. lol
