DB4S’ single driver features an aerofoil cone design – the same technology used in our flagship 800 Series Diamond speakers – for flawlessly accurate and articulate bass performance.

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

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

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