What's the BR (bass reflex) design recommended on the Decware site?

At the 2003 DecFest we heard the following FE208E based designs (unfortunately none of the drivers were broken in):

The prototype for Steve's latest HDT (high def tower) but I haven't seen plans, but its possibly the most complicated cabinet I've ever seen (2 passive radiators, vent, transmission line, wave lens, and crossing internal partitions). Sounded very nice.

Classic Audio's 2.5 (BR), driver had even fewer hours on it, response was not as flat with some bass boom, and side panel resonanted badly.

A relatively small standmount (BR) that Steve built, driver was even fresher, but sounded flatter/better with stiffer panels that IMO would integrate better than the others with a sub.

But I haven't seen or read mention of other FE208E based BR designs from the Decware site.
