Sims suggest as large a box as you can live with sealed or aperiodic OR open baffle.

If you want to do it the easy way like Nelson, here are some really nice 1 cu. ft. cabinets from Parts Express

https://www.parts-express.com/dayton...herry--302-753

Best I can figure from the specs they are 208.6 mm wide at the baffle, which is about 8.125" I believe. I think the baffle is solid. It's the bracing that has the 2 holes IMHO so the 8" driver frame should fit. -barely. These are an MTM model, it's a shame they don't seeem to have a "2-way model which are a bit wider.

PE discountined their curved boxes which were OK. My experience with the rectangular boxes is that they need so much remediation you might as well start from scratch.

PS: 1 ft^3 ~ 28 litres which is much smaller than you really want.

I believe the one I linked to is curved, so they seem to still be making the MTM ones.
Maybe that bump gives the illusion of bass!

Probably best plan to make a rough set of bigger boxes about twice the size to test, About the size of a Large Advent, if you go back that far..

It is… the smaller ones have disappeared.

The bump is bigger than i’d like and an underdamped response… as well as the real bass extension impacted.

You might get away with mulyiple holes drilled in the back and heavy damping over the holes.

The Delta-15A's, correct?

Yes, the sims show a bump, but so far it sounds good and chicks dig it...

For the 15", you've got the Beta, Delta, and Definimax, all of which
work pretty well.

TAD 1601's are nice too.
