Wharfedale Diamond A1 are active wireless speakers that use a separate control hub to handle power and sources. These aren't the first pair of wireless powered speakers but the majority of others require a cable to connect an active speaker to its passive sibling.
Wireless H1 Hub
Wharfedale's Diamond Active speakers use the H1 wireless hub to transmit left and right channel signals to the respective speaker. This means they are not tied together and can consequently be placed anywhere in a room. Each speaker in the A1 pair is powered by its own 50W amplifier resulting in consistent and fully optimised stereo sound.
Supporting both 2.4GHz and 5.8GHz frequency bands, the H1 hub can switch between either in order to maintain a stable speaker connection. The speakers must be kept within a 20m radius of the hub and near a power socket to connect to the mains.
There is a versatile selection of inputs to choose from whether you need digital optical and coaxial or two RCA-phono inputs for analogue sources. On top of this, there is also Bluetooth aptX. The speakers boast intuitive features including bass adjustment and a mono mode, which allows the speakers to be placed in different rooms for a very basic multi-room system.
The Wharfedale A1 uses a proprietary mid/bass driver with a 13cm woven Kevlar cone coupled with a 25mm fabric dome tweeter derived from the Diamond 200 series for clear high frequencies. The Diamond Active speaker also gets a specifically optimised crossover network which works to offer an immersive, bold and cohesive performance which is as equally as impressively refined.
If you’ve seen a pair of speakers from the Diamond 200 series, then you’ll notice the design similarities carried across to the Actives, such as silver-coloured driver surrounds, but the Actives do get new rounded cabinet edges. The Wharfedale A1 and A2 come in black 'leatherette' finish, with either gloss black or gloss white front baffles.
