This review is for Sound Town 4U PA DJ Pro Audio Rack/Road ATA Case with 13U Slant Mixer Top, 23.5’’ Rackable Depth, 4 Space Size - Pro Tour Grade (STMR-4U)This is a very sturdy case. All the parts fix snuggly together. Considering how strong it is, relatively speaking it is light, but I must say it is not a feather weight. And once I added the equipment to it, it takes two people to move it. The crown amp that I put in it weighs a lot, but I don't want to give the impression that the case is extremely light. In my opinion, it weighs what it should to be the quality that it is. When the case is moved after fully loaded with mixer, amp, and two small speakers,(amazing we could get all that in the case) there is no twisting or turning of the parts of the case. Everything is solidly secure in the case. I do nor thing that this case is water proof, nor do I think it claims to be. However, I can say that on the day I delivered this case to my client containing their entire sound system, we received a very heavy rain as we carried the case from my truck to the house. The case was always kept in it normal orientation, so it was not turned on its side in the rain. However, the case was completely wet on the outside. We dried it off with paper towels, brought the case inside, opened it, hung the speakers, powered it up and played music immediately because the was no moisture inside. That requires some pretty precise joins between the base and covers. I will be using this type of case for more if my equipment. I think the price is right for the quality that you get. A suggestion I would make is to have two handles on each of the long sides. With the case empty, it is fairly balance while holding each of the handles in the center. However, with that crown amp more on one side that the other, that one side is heavier and thus the handles in the center make picking it up a little more difficult because the case wants to dip to the heavier side. 4 handles would make it more stable. I am still giving this case 5 stars because it really met all of my needs for this sound system.
