SVS SB-4000 Overview
If you want a subwoofer that delivers more power and performance than any other sub on the market, look no further than SVS SB-4000.
SVS has a solid reputation for producing high-end subwoofers that deliver a lot of bang for your buck, and the company has just introduced a new series called the 4000 Series. This includes three sealed box subwoofers - the SB-4000 reviewed here, the ported PB-4000, and the cylinder PC-4000 - that fall between SVS's 2000 series and its Ultra line of subwoofers.
SVS SB-4000 Features
The SB-4000 is a powerful, rugged, and highly efficient subwoofer with a 13.5-inch driver that generates bass from 19 to 310 Hz, +-3 dB. The huge driver is steered by a double magnet system that's designed to keep the driver as light and compact as possible.
It comes with a 1200W MOSFET Class D amplifier that is powered by a built-in digital signal processor (DSP). The DSP is handled by Analog Devices and features double-precision 56-bit filtering for incredibly precise processing.
A Bluetooth DSP control app with volume, parametric EQ, low pass filter, phase, polarity, room gain, and custom presets lets users fine-tune the performance of the subwoofer. The app is compatible with iOS and Android devices, and a credit-card-sized remote control is included in the box.
In addition, the SVS SB-4000 is equipped with an active power factor correction (PFC) that lowers average current and smooths the incoming mains input, allowing for 1200W output from a standard 15A mains circuit. This feature is important for users who may be subject to the erratic voltage from their electrical source and can help prevent damage to the SB-4000.
There's also a 'Room Gain Compensation' control that can be used to tame the deep bass frequencies in smaller rooms so that they sound more natural. This feature is particularly helpful for small home theaters where the 'pressure vessel gain' can dramatically boost deep bass frequencies, which can sound bloated in these spaces.
It's also easy to daisy chain multiple SB-4000 units together, thanks to cinch and XLR inputs that let you use your existing AV receiver with the subwoofer. Lastly, SVS also adds an auto/on function and a 3-30V AC/DC trigger for maximum installation convenience.
The SVS SB-4000 is a large and expensive subwoofer that delivers more power and performance than any other sub on the market, and the company has made it easy to customize its performance with an excellent app. This makes the SB-4000 an ideal choice for serious bass lovers who want a powerful and versatile subwoofer that can be used in any surround system.
A massive 13.5" driver that weighs nearly 20 kilos is steered by a double magnet assembly. It generates deep and clear bass that's energetic and convincing in movies, yet natural when played back through music.
