            You sure must like drilling holes. What drivers are going in this one?

              I don't drill holes any more. I draw them and CNC cuts them for me.
              Like this:

              RaalXR20, Accuton mids and a pair of Iluminator woofers. I'll describe design an more details then I get home.

                Nice work Roman. The veneer is impressive. I look forward to reading about this project, and seeing more photos.

                    Thanks guys.

                    The design was developed by Rick Craig for a customer in MN.
                    Lucidita is the name of this speaker.
                    Instead of working from paper drawings I decided to just 3D model and lay out the parts.
                    Veneer is Makore. Initially we were going to use figured Bubinga but to be honest, I am not a fan and at the same time I was able to source a small bundle of Makore from the local veneer dealer.
                    Unfortunately, I am not going to get to listen to this design. Shipping Accuton over state line twice is not the best idea, considering it's ceramic and exuberantly expensive.
                    Hopefully the quality of the cabinetwork will fit the selection of drivers.

                      Cool combo of drivers. I recently came up with a theoretical design using the the Raal, Illuminator Mids, and Revelator aluminum 8" woofers... kind of a large speaker.
                      I like your internal braces, I am guessing you are doing a separate chamber for the mid/tweet section. And the parabolic cutout is for the port tube at the bottom.

                        Next machining operation is going to be a bit more challenging. Speaker uses 3" flared PE port. In the past I would use a holesaw to cut circular hole through the wall and then use a hand held router with huge radius bit to cut the flare curve. This time around I am going to attempt to machine it as a 3D surface on the CNC.

                          First machining operation is Pocketing. It's fairly simple. Router will remove stock from designated area to set depth (o.15") .
                          Spiral .25" downcutter will be used.

                            Next operation will be done with the same bit.
                            Horizontal roughing.
                            It should leave stepped surface that will be smoothed later.

                              Next, I will be finishing with .375" ball mill to create stepless surface on the inside flare.
                              This may be interesting for the Waveguide guys because in a way the port flare is a waveguide from the machining standpoint of view.
