And capping? Did you just update the caps with the same type and values?
What improved?
Thanks,

Depends on the speaker, Dingojazz. With AS-100s, replaced stock 4.7 uf tweet cap with similar value Dayton polyprop. On SP-1500s-n-SP-2500s, moi bypassed stock crossover net. On 1500s, a 10 uf Dayton polyprop was put on larger mid, & 6.8 uf Dayton polyprop on smaller mid (both mids shared 6.8 uf cap in stock mode); 4.7 uf Dayton polyprop on centre tweet, & 2.2 uf Dayton polyprop on flank tweet. On 2500s, which were bass shy in stock form, replaced stock 10 uf mid xover cap with 12 uf Dayton polyprop. As mids were similar, they were wired in series. 2500 is no longer bass shy. Since 2500 had provision for either 2.2 uf or 4.7 uf xover selection for tweets, a 4.7 uf Dayton polyprop went on lower tweet, & 2.2 uf Dayton polyprop went on upper tweet (similar configuration should work on your 2000s, Dingojazz; 4.7 uf's on lower tweets & 2.2 uf on upper tweet). Thin stock wiring in 2500 was replaced with 16 gauge (stock wiring in 1500s & AS-100s was sufficient). As good as your 2000s sound now, Dingojazz, they'll become tonally tighter, as well as more epressive-n-expansive, when those mids-n-tweets don't have to share the same xover cap. And, sub woofs won't be necessary. 73s para Sactown
Since I am not an engineer and do not think I am capable of doing a better job than the Sansui engineers on a 4-way 2nd order Butterworth filer, I stick with the stock values.

I hear u. No engineer here either, so If I venture, it will be the minimalist approach.
Thanks,
K.
