I recapped my Chorus crossovers about 6 weeks ago and I am extremely happy with the results using the JEM's.
I am one to usually spend what it takes to get the best quality "upgraded" parts but after speaking with Dean, who has built me some amazing exotic crossovers in the past, I took his advice and replaced the caps with the JEM's. The speakers have a wonderful clear, full and balanced sound. No complaints at all.
