    I buy it, if it places the woofer acoustically closer to the listening position.

        Thanks looks very similar but not identical to http://www.allaudioexpo.com/nav/details.asp?itemid=306 . Maybe I should order both and try to create a cad model for future reference.


        Is there any further information on the Jeff Bagby revolution?

          That is a threaded mount horn for compression drivers.

            True but it's much cheaper and I think you can break off the threads and create a modifier piece to interface with a tweeter.

            Probably much easier to get the WG 300 (it says it has a 38mm cutout), but the compatible driver is 30mm ~ 1 - 1/8"

              I ordered the WG 300 waveguide. I'm trying to pair it up with a tweeter.
              I'm thinking the Dayton Audio RST28F-4 could be a good option.

              The WG300 waveguide has an outer diameter of 168mm
              The SB17NRXC35-4 woofer has an outer diameter of 159mm; pretty annoying since that leaves a 4.5mm visual difference in the diameter from the edge of the baffle.

                That looks an awful lot like the horn zaph milled down here:

                My recollection is that this also worked well with:

                https://www.parts-express.com/peerle...eter--264-1014

                The face plate comes off that tweeter very easily with a little heat.

                Can't remember who used the mcm and vifa together. Somebody around here does, surely.

                  Did I miss something? The Buchardt S400 uses an SB15NBAC30 - NOT an SB17. (Or at least its something that SB made for them. The pictures show a 145mm driver marking.) If you use an SB15, the Wavecor WG 148 R is almost a perfect match sizewise - 150 vs.148 mm.

                    Their site says the box is 180mm wide. The woofers are almost to the edge - and they do say it's a 6" aluminum woofer. The SB17 measures 171mm in diameter.
                    I'm also guessing the elaborate crossover they show is not what's actually in the S400.

                      Serves me right - I was looking at the S300. I'm still skeptical there's that many crossover parts in the S300.

                        I believe there are 2 versions of this kit. One uses the SB ceramic 5", and the other uses the smaller Satori in about half the volume. They use the same SB Be tweeter.

                          On second thought, it does look like an SB17. My bad. I was thinking there was a round over on the front baffle, but it doesn't look like it.

                            FWIW, the S400 description says 3/4" tweeter, I'd bet it is the SB19ST. I imagine that small tweeter worked pretty well.

                              Or you can choose the less expensive ($511 less expensive) SB29SDAC instead of the SB29BAC Be tweeter. So there's a total of 4 possible versions. I don't know if there any crossover changes when you make the tweeter selection or if the SB29SDAC and SB29BAC are swappable w/o any changes.

                                Supposedly the 29 was a drop-in for the Be, according to one of the articles/pages. I'm assuming the xover is different from Be to Mini though.
