My basic tests now are using a B+K scope and my nice HP 200 oscillator set up for lissajous patterns. The sweep shows a 45d phase shift at the crossover 500c (bad), in phase at 1600c (also bad cause it dosent matter there 12db down) and 90d out of phase at 250c which goes with out saying. Im looking to go 3rd order in the pass band to gain that extra 45 but im going to have to order a collection of parts for the experiments. Thats where I stand now. Hobby fun yes?
