    What about the Bantam MTM?

      Any ported MTM design could be tuned using a PR instead.* I'd start by looking for any MTM design then seeking help to select and tune a PR properly.

        What are you looking for? Big? Small? Where are you going to use it? Do you have a price range? DIY Sound Group have a lot of new mtm designs that might fit your needs.

          I just ran the numbers for the SD315-PR with the Apollo MTM and with a single PR off the shelf you'd be able to run the system with 120W into the woofers and stay within the PR's excursion limits.
          2 Anarchy woofers in 1 cubic foot with the SD315-PR gives F3 at 42Hz.
          Two PRs with 180 grams of mass added will allow the system to soak up 250W and not exceed PR Xmax.
