I used a set of the 12" wedges for several years in my small club/Frat house rig. For the money, I think they are good boxes. They sounded better than a lot of wedges costing twice as much and they were light weight (a consideration when doing Frat basements on a regular basis with no one to help you load in or out). They would not do any low end at all (but very few single 12" wedges do that anyway), but they had enough output for small club work. We had very few issues with them, though we did replace a HF driver here and there (but I didn't see a rate of replacement that I thought was out of the ordinary) Overall, I liked them.
