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, 1 lab-tested.)
Praised: Powerful, clean, deep bass extraordinary for its tiny size; Compact aluminium chassis, easy to position and set up; Measured 106 dB SPL at 1m on an 80Hz tone, 1dB above spec.
Flagged: Limited maximum sound pressure levels / ceiling output; Awkward custom speaker-level connector limits cable gauge.
