What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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.
Bowers & Wilkins ASW610
Only one whitelisted tester covers the exact B&W ASW610: What Hi-Fi, which named it Best subwoofer up to £700 (Awards 2011). They praise agile, well-extended bass and authoritative, musical output from a compact design, listing 'Nothing' under cons. It is a qualitative listening review with no lab measurements; no other whitelisted outlet covers this model, so no cross-source comparison is possible. (1 sourced review.)
Praised: Agile, well-extended bass that belies its compact size; Authoritative, dynamic delivery blending power with musicality; Neat, well-made and well-equipped for the money.
