Just to start off, this was totally and 100% my fault. In no way is the DD-1 to blame.
I got the DD-1 from a friend of mine to test out, I will be buying my own DD-1 once the CC-1 becomes available as I KNOW there will be a combo deal.
Anyway, I was setting the gains on my SAX-100.4 and turn everything up to full power before distortion. Set my M3a and was done.
Turned up the system and it sounded great! Played a song or two for a friend, he confirmed it sounded better. Middle of song 3, I smell something weird, then the rear speakers just stopped and I saw the smoke. I was like , as I had forgotten to back the rear gain down as I still have stocks back there and they are only like 5 1/4". So thanks to the DD-1 making my signal clean, they at least died from over power and not distortion. lol
I will be making a full video tomorrow on me setting the gains again, and saying what I think about the DD-1. So far, a great product that I CANNOT wait to own.
