      It looks like you used a different material for the front baffle. Is it a better material for the formica adhesive, or is there another reason?

        That is definitely a walk on the wild side! You are definitely challenging yourself on these. I like 'em.

          It's because that is to what it was already bonded. Most countertops are particle board, or solid-composite. Since this is formica, it's PB.

          Agreed!!! I wasn't even sure I'd be able to build it as I envisioned it. I'm still grinning ear to ear knowing that I managed to bore that port into a 60 degree angled edge. I had to chisel a flat-spot first, and keep control of the Forstner to keep the bore straight and not go to one side, but I was able to manage fairly easily.

          It all comes down to the project goals that developed the inherent design and shape. I had a long-ish port, a 5" driver and planar tweeter, and was to shoehorn it into a 4.5 ltr box, with bass to about 54 Hz as modeled or lower post xover with added DCR.

          So-
          -the longish port needed more depth.
          -the 5" driver was fairly large and needed baffle real estate.
          -the height needed to accomodate the larger format tweeter size in addition to the larger woofer.

          With those goals in mind, decreasing volume and increasing height, while keeping same depth pretty much says: triangular prism shaped boxes.

          No- I'm not really expecting anybody to try and duplicate these. They are not easy to make. ;):eek:

          Thanks for the comments everyone! I still have more work to do!

            Looks like your yellow drivers are now gone from PE, per your discountinued reference above.

            Have the 5.8's gone up in price recently? They are now at $125 or so. Think they are worth it?

              Yep.. Neo-hikes made most of HiVi $pike as well. They were both about $62 originally. The drivers should be a drop-in in the way of the FR plots, if not minor modifications post-mock. I have not had them fully assembled yet to tell if they're worth it or not, but I'm working on it.

              (I know the Dynavox are still worth their price, and I still have the 2.5-way design you asked for awhile back if you still want it.)

              Thanks for asking,

                On the chance someone wants to try then out but was put off by the triangle could the neo 3 be mounted OB with the woofer in a 4.5L box for those still thinking inside the box :D

                  Re: "Trichotomy"- an oddly non-disparate design...

                  Typical. Just as I come across an interesting design, the driver is discontinued.
                  Oh well, I see enough interesting designs to try to build yet anyway.

                  The D5G is gone but it looks like the D6G is still around ($$$)

                  What about the F5 for a similar design? Obviously it's not a drop in replacement but it looks like it could be interesting too.

                    I'm sure you could! You could make it more like the Vijon, but keep the baffle the same size as the Tri' are setup. I'd be worried about the port being too close behind the driver, so keep it high.

                    The D5.8 is a near drop-in replacement, and could likely be swapped in without much trouble. Solen still has the D5G if you want THAT driver. You just have to pay more for it with Neo-jacked pricing.

                    The F5 can't work in as small of a box as the DG or X.8 series can, so that is a dilemma...

                      Looks like it's going to be a very interesting design -- the extended port could be made to add a lot of interest to the overall look of the speaker. Nice solution for getting an accurate mitre. How are you going to use the 1" round over? Do you have a shaper, or will you be relying on a large router and table?

                        Yes- the port will add lots of 'interest, visually' to the project! :D

                        I have a 3.25HP in the table, and a 2HP handheld and both will run the 1" RO bit. The 3/4" RO was no problem handheld, so I should be fine if I remove material gradually and step-up the radius as I go.

                        What I'm using it on- that will be revealed later....

                        I wish I had a shaper.....:eek:

                          Re: "Trichotomy"- Progress...

                          No pics, but the tops are attached and gluing up. I should be able to start on the bottoms momentarily.

                          I have the cavity in the base enlarged to receive the xover, since it was a tad small in dimension. Turns out the cavities will be deep enough for them when completed.

                          I'm in process of mocking the xovers on the actual layout, and am almost finished with both, awaiting solder after voicing. It's a tight-squeeze, but I was able to manage- even using poly caps for everything, the xover is no larger than the base of the triangles. It is however, about 2.5" thick. I was able to use both 4.7 and 10uF Erse TransientX caps in the design for the tweeter circuit. I had to use a 1uF on the 4.7uF and 2.0uF on the 10uF to trim the value. I hope the ones I used are favorable, as I don't want to get better trim-caps, but I will if they are a sonic hindrance.

                          That's enough for now!
                          Wolf

                          EDIT: Added xover picture setting in base of cavity.

                            I have to finish the second xover layout.
                            I have to attach the rear-most boards.
                            I have to paint the xover-cavities before xover installation.
                            I have to do the last of the flush/round/chamfer cuts.
                            I have to finish the terminal plates.

                            The main-body paint will have to wait until later.

                            I bet they'll be awaiting the xovers tomorrow evening....

                              I have to rub in the glue and sand them yet before I can start installation. I also have to install the terminals on the back. -And complete the second xover.

                              I should have tunes by Friday!

                                Really starting to like the idea of full active self-powered speakers. In cabinets that have no right angles.
