## What reviewers say

**QSC K12.2** — Only one whitelisted tester, Sound on Sound, published a hands-on review of the exact K12.2. It praised the tighter-than-expected bass, good vocal clarity and crisp highs, plenty of clean volume, and a sensible price with an easy menu system, noting only that the onboard mixer is very basic and the highs sound a little forward (which it framed as helpful for live use).
