The Bowers and Wilkins DB4D Subwoofer

The DB4D is Bowers & Wilkins first subwoofer in its range, featuring one 10" Areofoil driver for excellent and precise bass. It uses the exact same Areofoil driver which are found in the Bowers & Wilkins' flagship 800 series speakers. This large driver is positioned at the front of the subwoofer cabinet. This great subwoofer uses an all-new digital pre-amplifier, which ensures that the subwoofer works its best at all volumes. Thanks to the bespoke dynamic and room EQ parameters, this also makes the subwoofer perfect for any application; whether the DB4D was set up in a 2-channel system, home cinema or even in a home installation - is a perfect match for Bowers & Wilkins' latest 700 Series range. With the accompanying application for IOS and Android, you are able to tune your DB4D to suit your room. It will offer placement tips as well as changing the speakers 'Room EQ' to suit its surroundings automatically.

Who are Bowers and Wilkins?

Bowers & Wilkins are a company who needs a very little introduction, having been constructing some of the world's most critically acclaimed loudspeaker and headphone models for half of a decade. Starting at the entry level 600 S2 series, through to the new 700 S2 series audiophile range, 800 Diamond series and flagship Nautilus model. These different series of loudspeaker have been praised as the superior listening experience in both two-channel hifi/music listening and in multi-channel home theatre applications, having claimed a vast multitude of awards in both categories. A Bowers speaker can be easily recognised by the signature yellow Aramid fibre midrange cone, which can be found with their 600 series with the latest 700 and 800 Series opting for a silver 'continuum' cone.
