foamcore enclosure
Hi there J: As x and z have recommended, try foamcore build yourself...really fun material to construct experimental designs...fast too. Then you can spend big bucks to have a cabinet builder make them waf approved. ...regards, Michael

I've built cardboard prototypes from FedEx boxes that sounded much worse than wood cabinets even with the same volume. Is foam core stiffer, less lossy, etc. I'd imagine it would provide a similar result as cardboard.
Otherwise, I am a fan of large ported boxes. I love the Fostex 168z in an oversized ported box. Compared to 'optimal' boxes (simulated in WinISD) the larger box sounds more relaxed, balanced, fuller and just much better than the smaller boxes. In my case, I think I have a bit of a Loudness control effect going on.

The Dayton 8" full range always interested me but its frequency response looks hot. Perhaps an oversized ported box with an elevated bass response is one way to enjoy this interesting driver.

Thanks everyone for the extremely helpful info! I can't thank the forum enough for letting a no-skilled person such as myself (can't build anything out of wood haha) to pick your minds.
The original cabinet builder said he can build these K8's for me and also suggested a 27"x12"x12" (3/4" plywood) standard BR cabs with the ports tuned at 40hz as another option.

If you have listened to any of my sound clips or looked at the measured response, you can see that FC can sound great and measure well. It is stiffer than cardboard and the foam layer provides an added level of damping. Use of lots of bracing helps tremendously.
Or have a look and a listen at a short TL-Hypercube FAST with FC - this prototype took 4 hrs to make and cost less than $40 to make (drivers included):
