He said about 3 weeks, so figure about 4-5 tops. Pretty neat process though - he's actually having me measure my avg. ear height in my listening chair and he's going to make the tweeter cutouts to match that height. Also, my pair will be front ported, as that's what I prefer and Eric wanted to do the production version that way anyway. I like to feel the pressure in the room, plus front ports are much easier and more forgiving when it comes to placement.
I am really enjoying buying speakers from Eric. Where else can you go and spend "sane" $ and have somone build a custom speaker to YOUR liking. Great stuff!!
