    1D QRD (Diffuser)

    Four panels, two of which will be inverse.

    Each panel is 20" x 40". Their target is 715Hz, with a cutoff at 6,615Hz.
    They use 17 wells, and the period length is 493mm. (minus 3mm, because I will use the QRD frame for the end fin.)

            I've always wanted to build one of these.

              Done any work on these? I might end up building some QRDs for my next place...

                  I was delayed because I lost my pipe clamps. Tomorrow I should be able to start assembling it.

                    It took a few hours; I had help with holding up the big pieces as they went through the table saw.

                    It wasn't that bad, with my caliper and my new metric ruler. I love metric, it saves me a lot of time.
