The SVS SB-4000 is an excellent addition to systems for both audiophiles and movie fans alike. Making use of a specially designed SVS 13.5 inch driver and a huge 1200 watts RMS (4,000+ watts peak!), the SB-4000 offers a staggering bass extension right down to 19Hz! As well as the power, the SB-4000 also shows a remarkable amount of finesse to make it one of the most accomplished subwoofers you are likely to see at this price point or indeed a much higher one! Additional features include a specially designed smart phone app (iOS®/Android®) that gives users the ultimate level of control over all DSP functions and offers plenty of scope to adjust the performance to suit your room, system or simply your preferred acoustics.
