[QUOTE="Paul Johnson, post: 217754, member: 2643"] You’ve thought of the obvious stuff, like non-paper cones, so all you are really doing now is looking for designs, and sites like speaker plans and others have plenty of designs. Practically, though, it’s marine ply, not ordinary ply and a steel grill will corrode quickly and badly. Outside, the designs with slots not grills are attractive, but also make great nesting boxes, so some form of protection is needed. A place I visit regularly has old celestion 10” twin boxes used to do background music outside, and after twenty years, they look terrible, with rusty grills and faded and marked plastic style cabinets, but they work. This is on a pier, so salty atmosphere and wind and rain. Subs, out of the way, made from decent materials and painted in a decent finish, with plastic cones should do really well, I would think. For subs, nobody ever has managed to assess audio quality, as they just thud so driver differences are really a punt. I’d look at the design. Aluminium or steel, exposed steel bolts and magnets, or enclosed ones, stuff like that. [/QUOTE]
