If you are referring to the DM302, then yes I have had a pair for about 4 years. I paid $250 for them, and at the time they were pretty good. They had a lot more "sparkle" then my Magnepan MMG's. I think the Maggies are pretty soft up top, but I'm used to it.
I actually ended up replacing the woofer in the 302's with a carbon fiber driver I bought from Parts Express, and they now currently reside as surround speakers for my Xbox.
If you want to take them apart, there are 6 screws (1 in each corner and one in the middle sides), you can tell by finding the "inverted triangles" that just go straight back. You'll need a long phillips, like a 12" shaft. Crossover was pretty plain jane (2nd order), iron core inductor on woofer and air core on tweeter, all regular bipolar caps, and what looked like a zobel circuit on the woofer. There are two U shaped plastic clips that screw into the back of the front that hold the woofer in by compression. The tweeter is held in place by a plastic bar that goes across the back and is screwed into the back of the face plate. Box looked to be made of 1/4" (maybe 3/8") particle board (definently not MDF). Can't remember if there was any stuffing of any kind inside, don't think so though.
