The goal for these was the smallest size enclosure possible with at least a modicom of bass. Sims suggest <80 Hz (volume limited by size/excursion).
Neither of these have been built yet, The slot port version is the 1st cut at a nMar-Ken6M. drawn with 12mm material, good multiply recommended.

Looked at the sims again... 80 hz might be a bit optimistic, 70 Hz F10, slot port should get you a bit lower with a bit less bump than the round port. The uMar-Ken6 (which accomodates either A6P or A6M) is about 60% larger should get you to the magic 80. The full-size miniOnken for A6M looks like it will be based on 3.5-3.6 litre (still in development)
Chris is working on a set of sealed rear surrounds....less than a litre. To be used with (existing) Pensil7 LR & dMar-Ken7 centre

well, he's still looking at the drawing and brainstorming* the easiest way to fabricate an mirror imaged pair of enclosures with compound angles
I bet no nails and the 12" slider figure into it somehow
(*considering the remaining computational power, you'd only need a windbreaker )
BTW, an all Alp7 front row with dual woofer arrays, XO'd at 90Hz is is pretty nice little set up for a smallish (320sq ft) room
We built the big enclosure (3.6L) for the A6M. Works well.

320 sq ft is smallish?? Maybe in the North American continent , but most places elsewhere it would be considered largish I guess.

Edit: Probably we can lose the "ish" is largish

That's such a nice looking lineup ... and bet it sounds at least as good as it looks! Is there a box plan for the 3.6L I've missed?

In the true spirit of conspicuous consumption, some of the Ten Mile Point or Willis Point "cottages" have walk-in closets in the master-suite larger than that. OTOH, my son has made a deposit on a 1BR condo to be completed in a couple of years that will be 720sq ft, including deck.

There are indeed many more plans drawn than this ole boy will ever get around to building just for fun, and some that are included in detailed subscription plan sets. In this particular line-up
the enclosures left to right on the floor are: mFonken with FF85WK (~2L), CGR-Mar-Ken6m*with Alpair 6Metal (3.6L), 2 pairs of mMar-Ken6 with A6P (~5L) , and book-ended by mFonken with FF85K
the units on stands are mFonken / FF85K in bamboo plywood - by our calculation more net cubic volume of wood in these than air inside the box
* see attached PDF - note that front to back holey brace not indicated on this drawing, nor do I generally take photos during assembly, but we pretty take that as a given - even with a driver as diminutive as the A6s, some bracing is very beneficial

An updated today version of the pdf Chris had posted and refers to (cleaned some stuff up, added some detail)
I haven't got the link up yet on the site, so here is the Classic Golden Ratio cmMar-Ken6.2M plans.

These are the free plans.
