    Using a student is an even better idea than a breeze block, they are everywhere and inexpensive. I'd have liked to insert a reflex port into the one in front of me in the queue in the shop last night, buying £2.30 of 'munchies' and paying on his debit card.

    C'mon .. LOOK at the animated gif
    There you can see that the rear panel has a recess section
    Thereby creating a Slot port betwixt lower concrete chamber and the top one.. Where the external port is located.
    The designers are clearly Not idjits.

    Speaker enclosures of 1" thick DOW insulation Foam. Very fast to build and of minimal costs. Ideal for testing one's designs.
    Surprising bit is that the things sound Good! Wayyy better than idle speculation would infer.
    Putting serious doubts into the "What Enclosure Material" Teapot tempest.

    There is a fellow who makes / sells Exquisite Tractrix Horns out of Paper mache on his cnc molds.
    Not inexpensive though
