Hello Akhilesh I also got a tip from Martin on mail : http://www.quarter-wave.com/Project05/BSC_Circuit.pdf This shows a circuit for 206/207. This is a circuit for a ml tl project and it will maby be nice for me too if not the horn enclosure requires something else(maby not)? There is so much nice info on that website but in theese days im too busy to understand it. Thanks! Kane
