[QUOTE="Ron Kimball, post: 31263, member: 405"] Re: Coaxial Wedge Collaboration Not exactly DIY but I've commissioned Ramsdell Pro Audio to design and build me eight coaxials based on the Eminence 10CX. They will be 30/60 degree dual angle of minimal cabinet dimensions - two will stack together to form a 13.25" cube and fit in a supplied tray to make the pack stable. I'll be able to fit them two cubes high in my hatchback and they'll be part of my TH-Mini's plus RCF 310A's rig. Here's a rough prototype he built to make sure everything can still fit: [IMG]http://aspinock.com/Ramsdell.jpg[/IMG] They'll be somewhere around $300 each and will have a fairly sophisticated passive crossover to maximize GBF.
