maybe planet10 knows (?) (how about Larry Hitch at Madisound?) - couldn't locate anything.   From the descriptions I gather the following for the new 206 enclosures:

BK206En BLH 800mm high  x 280mm wide x 396mm deep with a  1.75M path, 10L chamber, 145Hz lowpass - then  E202B is a simple bass reflex (?) 440mm x 260mm x 265mm with Fb= 55Hz

that BLH looks close in size to BK20 - re:FE206En - without any break-in I got the following Qs - didn't bother to get Vas as it was going into an old Karlson coupler

Fs & Q's for FE206en - no break-in

You can buy the enclosures. I can't find plans yet.

The new enclosure looks a lot better than the "classic" one for the 206E, as it's more slender.
Perhaps it's only available as an expensive kit. But the old BK series plans were available.

Well frankly, unless these are a significant improvement over many of the "recommended" designs for previous versions of the FExx6 or FE/AV series which I've experienced,  there could easily be better enclosures authored by a wide range of DIYers.

Then there's the matter of how accurate are the newly published T/S parameters?  This had been cause for much frustration in the past for those who like to model performance in software emulation programs, and designed enclosures before drivers were in hand or fully broken in for final measurements.

I agree with Chris about the Fostex "recommended" cabinet designs. Almost all of the ones that I've heard weren't, quite frankly, that impressive and I've heard many of the enclosure designs that Dave (Planet10) and Chris have on the Planet10 website which are, IMHO, considerably better. 

In fact, the only Fostex (non-Planet10) design that I've heard, that I thought was pretty good, was the BB Front loaded horn w/Super Tweeter that somebody brought to the last Vancouver Island DIY Fest. I listened to it for some time out on the front (ground level) area and felt it sounded pretty nice.
I don't remember who brought it, but perhaps Chrisby can chime in on this.

Best Regards,

I may have heard them too, but am drawing a blank on a front loaded horn, may Dave can recall or has pictures?

edit:

well a little googling and, is this the one?






if so, I think those were Bob's FE166ESR in recommended Fostex enclosure - one of their better driver & designs IMHO
