With a mighty 1000 watts of digital amplification, DB4S delivers all the visceral rumble and punch you need to bring cinema sound to life.

Solid, dramatic bass is delivered through the rigidity and lightness of the uniquely-shaped, variable thickness Aerofoil™ cone.

Thanks to 1000 watts of digital amplification, DB4S delivers all the precision, control and authority you could ask for.

Digital preamplifier

DB4S uses a digital preamplifier featuring Dynamic EQ, for optimized audio performance across the available frequency range.

Adjust calibration and correction easily using the dedicated DB4S smartphone app.

I am happy to be able to conclude this review with the statement that, without any shadow of a doubt, the B&W DB4S is yet another great subwoofer from this great British company. What Hi-Fi? 5 Stars
