## What reviewers say

**KEF KC62** — Only one whitelisted tester—What Hi-Fi, using Newport Test Labs—published a hands-on, lab-measured review of the KEF KC62. It rates the compact subwoofer highly for powerful, clean, deep bass and easy setup, but flags limited maximum SPL and fiddly custom speaker-level connectors. (1 sourced review.)
