The box isn't finished; the corners aren't rounded off either. I was putting different drivers in the hole, to hear what I could hear; they're all different shapes.I've been listening to the FE168Σ's since I last updated that page, and they're the daddy. Best sound I've heard in my rig, although you have to listen on axis for the treble to go all the way up. I'll be starting to fine down the cabinets today, including inletting, rounding corners, flushing trim, li'dat. I'll take pictures as I go and update again.
