Hi Akhilesh! I´m building the Jeriko enclosure right now and have no crossover netw/filter yet. I was planning to use the original 208 Sigma driver but i learned it was out of production. Having noticed the 206´s are getting so much good critic in the different forums(some are not satisfied with the new 208?) i decided to go for the 206 instead. I heard about 2 simular project and was recommended to do so. The datasheets on the 206 shows a really smooth imperdanse curve and the frequency seems ok too? i live way up north(arctic) and i have to order the different components for a filter and will try to get it right so i dont spend a lot money on shipping. I use a small integrated tube amplifier. Thanks! Kane
