SB AUDIENCE ROSSO 18"
Front loaded horns can be a bit of a challenge to design. Folding them is difficult, making sure you’ll be able to build it is a bunch of work, and then there’s always the doubt, will it work as well as I hope, or did I screw something up? For this design I had a couple of constraints I tried to work in: 1. Buildable with a circle cutting jig and router, table saw, drill press, jig saw, pocket screw jig and hand tools. You’ll have to make some templates for things like the handles and stuff like that. There’s one part with a bunch of angles that would be made easy on a CNC. Contact me if you need a template…but you could also simplify that part and still have a great box.. I did cheat and use the little hobby CNC I have for parts, but you can absolutely make it with the stuff I described. 2. Can be made with common sheet goods, I built mine using Baltic Birch, and if it’s going to see serious long term use I recommend sticking with that. In a pinch though you could probably get a lot of life out of lesser grades of plywood. You’ll lose some output because those materials will flex more, especially around the access panels. Avoid OSB, MDF, or particle board though…no good. 3. Size. This is where I expect to get a lot of, ahem, armchair speaker designing. I wanted this to be easily transportable with vehicles I own. And since I don’t own a 16’ box truck with a 90” inside width I designed them to be moveable with my full-sized Ford pickup. And I wanted the maximum output I could cram in that vehicle. That meant external dimensions of 48”x48”x24”. Someone buy me a box truck and I’ll design for that for now on. Read the full article [Downloads].
