Design given to me by Graham Day-Myron using the Kinima (Zetag) speaker brand long-since gone. I made the first pair as a quick and dirty prototype to gauge the performance potential around March 2004 or so. After liking what I was hearing, I embarked on a very labor and time-consuming endeavor to create something I would live with long term. I documented every step of this process and am still impressed with the final upgraded configuration I use today.
