  • The Peanuts my MWAF 2017 entry

    These are the peanuts, and grew out of my desire to use a waveguide in a build. They use the Hivi m8n and Dayton rs28a in an aluminum waveguide that I turned on my lathe. The waveguide started life as a 2" x 8" dia chunk of aluminum, and the cabinets are a plywood skeleton covered in three layers of 1/8" mdf that was kerfed to allow the tight bend.

      It looks really nice! Did you CNC it or use a template?

        I used a template for the cabinet, and a pattern follower on the lathe.

          Amazing work! That's a serious waveguide. Love the veneer inlays too. Wish I had been able to see and hear them in person.

            Excellent work, Nick! And congratulations on your 1st place finish! Very well deserved! If I did not know better, I would have guessed that that wave guide was machined and polished out from a solid block of aluminum. Incredible finishing work. Edit: Oh, wait, I just re-read your description. That was machined out of a solid block of aluminum. So the waveguide on one speaker at InDIYana must have been a wooden prototype. My mistake.

              Yeah Bill the one at indiyana was one of many prototypes, I found that I could knockout a mdf version in no time, but the aluminum ones are about 4-5 hours and much more expensive.

              Thanks for the compliments guys.

                  I generally like a brighter sound, so I was really surprised how much I liked their sound. These sounded smooooooooth! They also sounded 10x better than they did at InDIYana. Amazing furniture work, and that's an understatement.

                    Thanks for the kind words guys. Yeah Brian, I know you like brighter but I go for flat. The reason they sounded ok to you may be their off axis response. Kevin I can't compete with cnc, but I enjoy myself.
