Description

B&W DB4S Overview

The design of the DB4S is similar to that of its more expensive counterpart, the DB3S, but it's fitted with a slightly larger cabinet and has an attractive ash wood veneer on its front baffle. The grille is magnetically attached to the baffle, rather than pegged into place like the previous DB-series models, which is a welcome design improvement.

The DB4S is also a front-firing port speaker, which means that it can be placed close to a wall or other surface and still deliver its bass in a controlled manner. This is a welcome advantage for home cinema systems, where the sound can be distorted by too much direct contact with the ceiling or walls.

B&W's app can be used to select a main speaker and then the DB4S can be paired with it, with the system automatically adjusting its response to match the speaker. You can then choose to adjust the low-pass frequency, crossover slope, and phase if you wish.

B&W DB4S Features

B&W's DB4S subwoofer is a real find. It's a surprise appearance in the company's long-running DB series, which consists of three double-driver subwoofers arranged in what B&W calls a 'dual balanced' configuration, with the top-of-the-range DB1D model being fitted with an internal amplifier rated at 2000 watts (though this is not actually the case with the DB4S).

The DB4S is one of B&W's budget-priced subwoofers and is located directly below the DB3S, which is also positioned a step lower in Bowers Wilkins's powered subwoofer selection. While it does lack some of the high-end features of the DB3S, it's a powerful performer, with B&W's usual superb piano lacquer finish available in either gloss black or gloss white, plus a choice of Rosenut wood veneer.

The driver in the DB4S is a unique 'Aerofoil' cone, which was originally developed for B&W's 800 Series Diamond loudspeakers, and whose foam core is variable in thickness across its diameter. As a result, it has excellent linearity and smooth frequency response.

It also has a very stiff, yet very light cone material that makes it extremely rigid and which is ideal for delivering bass impact with a minimum of distortion. It's a great design feature that really sets the DB4S apart from other single-driver subwoofers in this price range and is definitely a big advantage when it comes to the dynamics of movies, especially those with strong bass effects.

The DB4S is fitted with a 1000-watt digital amplification unit that can be controlled via a dedicated app, available for iOS and Android phones. This allows you to calibrate the DB4S with ease and is particularly useful if you're using it with B&W speakers because presets are pre-programmed in the app.

Calibration is very easy and the DB4S's crossover frequencies, slopes, and five-band equalization are all easily set and adjusted. The only problem is that you need to ensure that the DB4S is connected to a main speaker before you run the calibration.

  4. After Sales Support - The only issue with Hi-Fi equipment is that you will not find local service centers in every city. Most of the brands have their service centers only in the metro cities and hence it becomes difficult for the customers who are living far away places to claim warranty. At AV Kart, we solve this problem by arranging pikcup and drop facility from the nearest service center with the help of our logistic partners.
