Maybe somebody will find this interesting enough. I find somehow that my tastes may not particularly jive with modern aesthetics. If not for jeans and tee-shirts, I'd really be screwed with regard to my fashion sense. I have to ask women what color to paint my house, etc.
Anyway, I could not find grilles for my Tempests that I liked. Everything kind of looked like cheap hubcaps from a J.C. Whitney catalog, or a little too far out for my tastes. I don't usually really think about what other people will think until it's too late and I've already dove into it.
I weld for a living and have an industrial sized setup here at home as well. Grabbed some aluminum scrap from work and brought it home and just went at it.
Cut some MDF rings with the router and made the recesses on the under side a snug,twist fit onto the thick gaskets of the Eminence woofers. The MDF rings are saturated with epoxy resin. Also made recesses for the partial grille flanges. The 1/4" aluminum rods were bent using a gradual layout to closely match the circumference of the rings. I didn't weld the rods because I didn't want to see the weld beads there, so I silver soldered them instead. Also so that it wouldn't distort the rods or the rails.
Test fit. There's 4 - #14
stainless steel oval head lag screws holding them onto the rings which I painted black using an etch primer for nonferrous metals.
Final result. I do have the option of fastening the rings through the driver mounts under the grille flanges but they hold tight as is for now anyway. It takes a decent tug to get them off, otherwise they need to be twisted on/off.
Love these speakers. They have been on every day for hours on end since I built them and for music only. They're being played on an old Denon 3805 in Pure Direct mode with a sub that is hooked up to a 3000dsp amp. I have also since gotten rid of the ghetto boxes under them and built risers for them out of aluminum as well. Was a lot of fun to do.
