I have been building speakers for as long as I remember without really knowing what I am doing. My first major project was to build the Rogers design TL for KEF T27/B110/B139 using a crossover design provided by a generous employee of a hifi store that no longer exists. Alas, this was stolen many years agi, and I am now rebuilding a pair of KEF Cantatas, trying to turn them into infinite baffle versions of KEF Concertos. I have also done some updating of my Snell Type A3s. I have spent many hours pouring over diyAudio posts to learn about TL and crossover design. Perhaps some day I will be able to contribute something other than questions.
