The Diamond Active Series from Wharfedale delivers wireless connectivity with a difference. Whilst not the first stereo speakers to offer integrated amplification and Bluetooth connectivity with compatible devices including smartphones, tablets and computers, their ‘True Wireless’ technology ensures greater flexibility than many similar designs says the company’s recent press release.

The Diamond Active Series comprises two models: the Diamond A1, a classic ‘bookshelf’-size speaker (31.5cm high), and the Diamond A2, a larger floorstanding design (91.2cm high). Both models come in pairs, in the manner of traditional stereo hifi speakers, and include a 50W amplifier in each speaker to deliver a combined ‘system power’ of 100W.4613_Wharfedale_Diamond_A2_(black_baffle)_online

Many ostensibly similar stereo-paired Bluetooth speakers incorporate the amp circuitry and Bluetooth receiver in one speaker, with a cable connecting this powered speaker to a second, passive speaker. This means that while you can connect your playback device to the speakers wirelessly, the cable between them limits the speakers’ placement. Wharfedale’s Diamond Active Series speakers work differently. They include a wireless hub, to which the playback device is paired via Bluetooth (with support for aptX codec). The H1 hub then conveys the left and right audio signals to the appropriate speaker via uncompressed wireless transmission, allowing greater freedom in terms of positioning. As well as removing the need for the speakers to be connected together via a cable – that’s why they’re calling it ‘True Wireless’

To enable interference-free wireless transmission, the H1 hub avoids the often-crowded 2.4GHz frequency band, focusing on 5.8GHz instead. The intelligent wireless module has the ability to switch automatically between frequencies when required, thus avoiding any local interference wherever the speakers are sited. Each speaker may be placed up to 20m from the hub; the only other siting requirement is that both speakers, with their dedicated amplifiers, need to be plugged into the mains.

Digital inputs are supplied in both optical and coaxial flavours, while two RCA-phono inputs cater for analogue sources. Touch-sensitive controls on the hub’s top surface allow adjustment of volume and input switching, while a remote control is also included.4599_Wharfedale_Diamond_A1_(black_baffle)_online

Additional controls on the speakers’ rear include bass adjustment (+/- 6dB), allowing the user to tailor low frequencies to suit the speakers’ position in the room. Each speaker can be selected as either ‘left’ or ‘right’ in a stereo configuration; a mono mode is also available if the speakers’ positioning is not suited to stereo. This mode can even be used to create a simple two-room setup – useful, for example, if the user is entertaining friends and wishes to place one speaker in the living room and one in the kitchen.

Both Diamond Active models sport proprietary bass/mid drivers with woven Kevlar cones – one 130mm unit in the A1 and two 165mm units in the A2 – as featured in the Diamond 200 Series. The cones incorporate semi- elliptical ‘break-up’ areas, which smooth the response throughout the audible range, while rear-firing reflex ports augment the bass. The 25mm fabric dome tweeter is also derived from the Diamond 200 Series

Wharfedale’s Diamond Active speakers are available from October, with RRPs of £599.95 per pair for the Diamond A1 and £999.95 per pair for the Diamond A2 (including the H1 wireless hub).
