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.
