The Bowers & Wilkins DB4S model is the most compact subwoofer in the DB series, perfect for building a high-class home theater or stereo system in a small room. Despite its relatively small size, this "baby" is capable of providing confident, tight, and deep bass.
The active subwoofer Bowers & Wilkins DB4S is housed in a sealed enclosure and features a 10-inch driver with Aerofoil cone, as well as a 1000W Class D amplifier. The subwoofer is equipped with a digital preamplifier with dynamic equalizer, controlled through an app, and operates in a frequency range from 10 to 350 Hz. The finish of the subwoofer is available in the same options as the entire 700 S2 series of speakers.
To control the Bowers & Wilkins DB4S, a special mobile app is used. It completely replaces any control buttons, and even the display on the B&W DB4S. Therefore, to use the subwoofer, you need to install the DB Subwoofer Bluetooth app on your smartphone (for iOS or Android).
The app allows you to select the input (RCA or XLR), and the type of connection (Stereo or LFE). You can also adjust the input signal gain, its equalization (flat, music, movie, or custom), control stereo settings, and automatic standby mode. It even includes automatic sound parameter correction based on the room, using the microphone built into the smartphone. In this case, the subwoofer generates a test signal, and the smartphone needs to be sequentially placed in seven points in the room.
The Bowers & Wilkins DB4S has two RCA and XLR inputs, two 12-volt trigger connectors, and an RS232 port for external control. Spikes or vibration damping feet are included for subwoofer installation. The dimensions of the B&W DB4S are 360 x 377 x 368 mm, with a weight of 26 kg. The subwoofer B&W DB4S pairs excellently with the 700 series speakers, as it uses similar lightweight and very rigid Aerofoil cones. The Aerofoil cones have varying thickness, providing increased strength in critical areas. This ensures smooth piston movement of the membrane, which, according to the manufacturer, can resist bends and deformations much longer than traditional speaker diaphragms. The B&W DB4S subwoofer also pairs well with other speakers, such as the CM series.
