  • Selah Audio Anniversario

    Building the Anniversario kit from Selah audio! First DIY build and a long time member so thought Id share the progress here. I took quite a bit of liberty with the box design but kept the baffle in dimension per the specs listed for this design.

    Its going to be a Translam Baltic birch build. Laminated top/bottom/front with Highly figured Bubinga veneer!

    Every wall is ~1.75" Thick. 1/4" routed through the center of all side/back walls filled and compacted with clean sand. Internal bracing every 3". Top, bottom, and baffle piece all have a sandwich using 1/8" Mass Loaded Vinyl.

    Each piece was rough cut to shape, then routed inside and outside with a template router bit. Heres a couple pics of the pieces routed and stacked.

    Next each piece had the sand channel cut out with a jig saw. Here you can see them glued up a few pieces at a time. This picture is after a few hours of clamping.

    Stacked, Sand filled, and crossover strapped to the bracing. Sand filled with compaction and vibration.

    Both cabinets done and rough sanded to 150 grit. Next step to to shape the front baffles in the next day or so. Both baffles have already been glued up with the MLV sandwich.

      Very ambitious.

        Agreed. Have you made sure that the volume of the box has not radically changed (accounting for bracing, the tapered shape, and the extra thick walls)? If not you might run into some issues.

              It is going to be beautiful - one observation, however, about many of the translam cabinet builds. Are the backside of the woofer through hole rounded over or beveled?

                Nothing a round-under bit can't fix....

                MLCS used to have a 1/2" for $30, but it's NLA.

                  Looks like it's going to turn out nice. If you don't mind me asking, roughly how long did it take you to cut all those pieces?

                    Yes I made this up with cad software and had measurements of internal volume. This had quite a few hours of thought behind it.

                    Rick built the x-over. I just had to zip tie it. If it's wrong I blame him :P

                    On track for about 40lbs per speaker, without stands lol. Bricks!

                    As wolf posted, I'll be putting on the back woofer chamfer after I have the baffle finalized to make sure all the holes line up perfect. It's so thick I'll Likely free hand it with a 36grit spindle belt sander.

                    Each speaker was 24 pieces routed. Inside/out + the sand channel was probably 6+ hours per box? It certainly look me forever because I never had that much time in a single sitting. And the sanding is a nightmare. I had a bench belt sander that saved a huge amount of time for getting them rough shaped when they were stacks of 4. Then the real pain was making sure I kept the body straight in the curves. I accidentally made some dips I had to use a long block to remove.

                    A learning experience that's for sure!

                      My new job has large tablesaws, CNC routers, and a warehouse full of MDF, particle board, hardwood veneered plywood, sweet veneers, a plethora of laminates, Corian in every flavor, and granite cut to order. I hope to take advantage of the CNC router to build a stacked cabinet similar to yours but using MDF, but go for a polished black Corian baffle with one of the more stripey veneers we have.

                      Looking forward to your finished product!

                        Looks amazing so far. I've been wanting to do a project similar to this. Translam is awesome. How did you line everything up? Most I have seen with translam use some alignment holes.

                          I used a template bit with router so the peices were perfect to start with. Given that I was able to use straight peices of scrap wood with a clamp to squeeze the sides together and that kept it straight as I applied the clamps to compress top/bottom

                          I glued up 4 peices at a time into small stacks. Once dried and I rough sanded the glue off those I stacked those together to make the full box. So I never had to align more than a few glue joints at a time

                            Yup I modeled it after their Sundog actually. Nice looking cabinets.

                            Bit more progress today. Got the baffles rough machined. Found out the front on each cabinet wasnt as flat as I thought so I had to level it with a router... And naturally found that my router jig for this had warped so I had to quickly toss together a new throw away one for just this job. Not perfect but it did the trick. Also cut the angle on the baffles to match in with the existing curvature. PE not letting me post pictures ATM for some reason so will upload later.

                            At this point pretty much just have to sand in the baffles to match the cabinet perfect, Veneer, and cut the speaker holes.

                              But, this could be useful. I just wish it didn't cost so much.

                              Here is the Mother Load, @Wolf! I would have mentioned it sooner, since I know you've been looking for some time now (as have I, off and on), but I only just now found it.
