🧠 Summary:
-
✅ Cross Cap = best for budget crossovers and large values (woofer filters).
-
✅ Standard Z-Cap = great all-rounder for midrange/bass with improved resolution.
-
✅ Superior Z-Cap = optimal for tweeters/mids in serious hi-fi builds.
-
✅ Silver Z-Cap = ultra-high detail; choose when only the best will do.
-
✅ Alumen Z-Cap = for natural, rich tone, especially in vocals/mids.
