HomeCinemaMagazine.nl (Netherlands) Reviews the SB-4000 Subwoofer
"With the SB-4000 you get a subwoofer that is immensely powerful and dives very deeply - and that also works smoothly in large spaces. It is also incredibly fast, so that bass is served accurately and compellingly. At the same time, it is also able to subtly support your surround speakers. It is not only suitable for rough work. We never thought to stick this label to this giant, but it is ... yes, refined."
