Improvement on S3 crossover
I bought S3 and found lower frequency covers the mid. After opening up, saw 2 Wima 0.1 and 1.5uF for high, ICW 4uF for mid and Alcap 30uF for low. Materials are not from high grade components. Replaced Wima 0.1uF with Solen, 1.5uF with Mcap Zn, 4.0 with Mcap Zn 3.9uF and here the culprit, the 30uF now replaced with 22uF Solen. Have to reduce the low section because the small box and 4 inchi driver is not suitable. Just completed and tried out for an hour, overall clarity improved. Will continue tonite and will update after 100 hours of run-in. I still have 12uF Solen to repalce the 22uF if found not suitable.
