“QSC has a reputation for producing effective PA equipment for musicians at sensible prices, occupying the middle ground between more affordable but less refined systems, and high-end esoterica. This new K.2 series of active speakers, which are certainly attractively priced, would appear to offer plenty of clean power and include overall four-band EQ plus basic mixing for stand-alone applications. At the given pricing, there is nothing to complain about it.”
