I know I'm a little late on this, as I just saw this question, but I have the D2-ISO-5's (has the bottom subs). They are great speakers but because they are chrome, they are difficult to clean and show any minor scratch. The only issue I have is the tweeter, as they are pretty delicate; I have since blown a tweeter and am scrambling to find out how to fix. Unfortunately they are no longer sold in the US and Im trying to see if I can send back to the factory for repair. Anywhere in the US they can be repaired?
