I just got a great deal on a pair of CS3's. Just 3's no dot anything. They sound great. I found out that they originally came with a bass equalizer. I bought one "working perfectly" on ebay, but, it is problematic, scratchy. I brought it to a shop recommended by my speaker repair place.
I mentioned to the tech that I believed it was only used to boost the bass of the 8 inch woofers, but, he led me to believe that it did more than that, almost like it was constantly monitoring the signal and adjusting it accordingly.
Sounds to me rather impressive for a "black box" .... any info on this?
Thanks!
