I would like to build a pare of outdoor speakers, robust enough to be left in the rain and sound good (non-audiophile's might say “Wow – they sound great!”).
First the cabinets and cones: I'm thinking sealed. No ports – no critters. I'll probably have them about 6 to 18 inches above the ground, about 15 to 20 feet separation, 25 to 45 feet to the listening position (floating in the pool – sitting on the deck). Ideally they will disappear into the foliage. To weather proof I was thinking of covering the exterior with fiberglass and extending the fiberglass over the front like an awning, (perhaps in a horn shape?). Now I realize that that last idea may have betrayed my experience or lack there of, so be kind.
Second the sound: there is a large area that we will be listening, I don't expect the world (unless you tell me how I might get it) I was thinking of a full range (nice and simple?) or two way.
I'm looking for cabinet designs and driver (and tweeter) recommendations. I would rather go deeper (front to back) than taller.
Any pointers, links, ideas? All are welcome.
