If memory serves me, I believe Rockford actually had something similar to the DD-1 out back in the 80's early 90's but may have been a dealer only item.I actually got to play around with this at CES...
If it works like it did in the booth then they may be on to something for sure.
According to them it was "inspired by" the DD-1 actually. They claimed to made some adjustments and such...but they wouldn't go into details about who designed it or what alterations were made...non the less it performed very well at the show.
