Hi Till,Nice pics! That sub came out real nice. I noticed your using 2 of the JBL 3677s for you HT. I have a pair as well and built the crossovers last week. I just created a simple 12db butterworth at 1200hz (1.5 mH coils and 12 uf caps). I did not add an zobel compensation or anything of that sort. Can I ask what type of cossover you built and if you added zobel compensation? Thanks.
