I have SDA2's (5 driver) from 1986 and have a possible opportunity to pick up a pair of SDA 1C's. I'm going to rebuild the xovers on the 2's but was wondering about the value of maybe picking up the 1C's and keeping the 2's as surrounds or selling them to a friend. Or just skipping the purchase and sticking with the 2's.
I guess what I'm looking for is opinions on which set (sound-wise) would be the better "keepers". I haven't even researched 1C's so I'm not even sure of their benefits (or not). Do they have two dimensional drivers, two xovers, etc.
