Gone were the days of using the striking yellow Kevlar midrange cones, the new B&W 603 looks more minimalistic with its 6 inch (150mm) Silver Continuum cone FST (Fixed Suspension Transducer) midrange driver. Above the midrange driver, you will see a 1 inch (25mm) Decoupled Double Dome aluminum tweeter. There are also two 6.5 inch (165mm) paper cone woofers. It is a three-way speaker design with rear-firing Flowports (bass ports). You’ll need to find space for them, if you have no choice but to place them nearer to walls and find the bass a bit too much, you can always use the foam port plug. The Bowers and Wilkins 603 do look more modern and stylish now, changing the midrange driver to silver color is a good call.

The magnetic grille looks nice on the speakers as well, keeping them on, may let them blend in nicely in most home interiors. We were expecting high speaker sensitivity but at 88.5dB, it is still not bad. The frequency response is also not what we expected, it is 48Hz-28kHz (±3 dB) which is good though. The nominal impedance is 8 Ohms and a minimum impedance of about 3 Ohms. The recommended amplifier power is between 30-200 Watts. With the current data we have, it seems that we need high power output amplifiers to drive them. There’s a probability we may need to integrate an active subwoofer into the mix to supplement the subterranean bass reproduction.
