The SVS 4000 Series subwoofers will shortly be available for UK AV enthusiasts. The SB-4000 sealed, PB-4000 ported and PC-4000 cylinder designs sit between the 13-Ultra and 16-Ultra models in the SVS range, offering 200W more RMS power and 600W more dynamic power than the 13s, under the command of IR remote control and smartphone app.                                          

4000 Series’ Sledge STA-1200D amplifiers, which are rated at 1,200 watts RMS / 4,000+ watts peak, use an efficient high-current Class D design combined with a fully discrete MOSFET output stage.

The 4000 Series’ 13.5-inch drivers have dual-ferrite magnet motor assemblies in conjunction with edge-wound aluminium voice coils and lightweight, rigid composite cones, 50MHz High Resolution Analog Devices DSP and room Gain. Active Power Factor Correction (PFC) serves as a line conditioner, surge suppressor and voltage regulator to accommodate wide voltage fluctuations in the household supply and eliminate the potential for ground loop.

The 4000 series’ smartphone app for iOS® and Android® controls all DSP functions including: volume, low pass filter, phase, polarity, room gain, port tuning, three custom presets and system settings. An integrated 3-band parametric EQ allows for frequency and Q factor adjustments down to the single Hz level with four different slopes. Two-way feedback shows updates in real time on both the app and subwoofer interface. The App connects over Bluetooth, even when the subwoofer is out of sight.

SVS 4000 Series Subwoofers make their UK debut at Bristol Sound & Vision, room 332 with Karma AV.
