Product Review

If you're looking for premium speakers to fill your home theater and handle a variety of musical genres, you can't do much better than the KEF R Series. Transparent. Well-rounded. Superb rendering and imaging at all volume levels. A powerful-yet-compact subwoofer. states High-Def Digest in a May 2016 review of the R400b.

Measuring a compact 14 inches deep and wide, the R400b delivers a surprisingly massive low-end with an incredibly quick response. The subwoofer's twin 9 inches bass drivers perform with little excursion, meaning your bass frequencies hit hard and can cease instantly.
