Celestion SL6Si Information
I recently laid hands on a pair of SL6Si's. What a great speaker, even by today's standards! Interesting to see a 30 year old design hold up so well. Anyway, just wondered if anyone out there might have a manual for these or a copy of one I could get? Nothing online that I could find... thanks! :)
