Hello everyone, I'm new to the forum and think it's great.
I have a pair of SDA-II speakers made in 9/83 that I purchased in 84. They have the SL1000 tweeters which I am currently upgrading to the RD0194-1's.
I have been driving this pair all these years with a Hafler DH-500.
Does anyone in the forum own/owned this early model?
If so, anyone done any crossover upgrade work?
Anyone have a schematic?
Thanks in advance
