Five drive units in one cabinet, with a stated 35 Hz–24 kHz frequency response.

Universal 100–240 V input with sleep consumption stated as below 2 W.
No wired audio input: the USB-C port is for service, and wired networking needs an Ethernet adaptor that is not supplied.
Needs mains power at all times (no battery), and at 650 mm wide it needs a large shelf or the separately sold wall bracket.
Bowers & Wilkins' own figures disagree on weight (6.6 kg vs 6.5 kg), and the 240 W rating has no stated measurement basis.
