Building a set of Fastlane Audio Eliptrac 400 wood midrange horns. These were developed by Dave Harris and Al Klappenberger. Going to run BMS 4592 MID drivers on them. They are a 310 Fs horn. I bought the kit form. I am going to do a side by side comparisson with my Altec 311's with 288-8G drivers. Pictures to follow as soon as I figure out my new camera.
