Although qsc is described as a product made in china made of small pieces that do not pay the high price of these, sound, features and physical manufacturing take great prices for sure! I bought these boxes having been satisfied hifi level as it does not match any series of JBL and other popular brand, because I had the k10 which also have this sound without coloration, without any need equalization. Fancy a purchase, not need. This is not a box with a crazy descent, but with outstanding sound linearity, based on what the head should be focused. I would not be afraid to put face to face with your hp if you cross they do not sound that good. I compared with before purchase yamaha yorkville, DB, jbl eon prx, lag, maybe even more, and since I have I see how the other hp did not, the other areas that are hot and cold ... Qsc is linear sound!
