I'd have to take a guess at this point, but I think it's around 30-35 lbs. The case has a great pull out handle and wheels for moving it any distance. There are also nice grab handles on both ends. I've lugged it around one handed but only short distances. It's a very balanced two handed carry.
For everything that's included in the case the weight seems reasonable: DL1608, 13mm birch internal mounting frame, internal power strip, 16 channels of 3 way split, output/power panel, rear rack rails, 2 space vent panels, wireless IEM transmitter, Airport Express, external power strip (nests in the lid) and cabling to hook it all together!
