Another Award for Audio Pro is barely news anymore, but the fact this year the Drumfire displaced the Naim Mu-so – a product almost double the price we once heralded as the nearest to hi-fi we’d heard from a wireless speaker – as our most expensive champion in 2018 is proof it is operating on a different level to anything else around it. Most importantly for this particular speaker, though, is the question of how well Audio Pro has integrated its voice control abilities, and whether there is enough reason to pay the extra over a regular Addon C5.

Over the years it's also built up a portfolio of products that covers every need, from portable speakers ( Sonos Roam), to soundbars ( Sonos Ray), and everything in between. So whatever kind of system you're building, there's a Sonos speaker (or three) for every room in the home. Though there is a pair of unknown quantities in the Audio Pro line-up as far as we’re concerned – the Addon C-Sub can help those smaller speakers delve deeper into the low frequencies, while the A40 is set to receive a wider release following its design for the company’s 40th anniversary– our time spent with the rest of the company’s speakers allows us to confidently celebrate it as the best-sounding multi-room suite available for the money. The deep integration with Apple’s ecosystem also makes it blissfully easy to set up. Paired with an iPhone all you have to do is scan for the speaker and run through a few on-screen commands to get it fully up and running and integrated with your smart home setup. The entire process only took us a few minutes. Multi-room speaker systems are tested for sound quality, features, ease of set-up and use, and overall performance. And we aim to test multiple products in each family, usually involving at least two wireless speakers and a soundbar but this will vary depending on each system's product line-up. As much as anything else, your chosen path for migration to multi-room should be about whose speakers you want around your house. For us, Audio Pro makes that particular decision admirably simple.The Addon C3 has a 9cm woofer, it measures 10cm on the Addon C5 and Addon C5A, while the Addon C10 has the largest at 13cm. The power output from the Class D digital amplification rises in similar increments: 15W, 40W and 80W respectively. All four speakers house a large circular volume control flanked by sets of four smaller buttons on the top: for power-on, play/pause, input selection and Bluetooth pairing to the left, and pre-sets to its right. This includes a clever process where the speaker uses in-built sensors to optimise its sound settings for its position in the room. Testing the feature by moving it closer to a wall in our listening room, our reviewers could hear the HomePod 2 adjusting its sound in real-time. Very impressive. What Hi-Fi? said:Sonos might be among the best in the business, but it isn't your only option if you want to go multi-room.

It is the use of a BMR, or Balanced Mode Radiator, tweeter that is most canny, however. Among its many benefits, this flatter-faced driver has the ability to offer wider dispersion than a traditional tweeter – up to 180º in fact – and so can make the most of the A10’s cylindrical form, making it far less fussy when it comes to positioning. On top of the sub is the second part of the Drumfire’s set-up, containing two 11cm woofers and a 25mm tweeter. This box has an RCA input for an external analogue source, as well as an ethernet port and 3.5mm input.Sized and shaped like an ashtray, the Link 1’s duties are to collect song selections from the app, connecting to your home network via either wi-fi or its ethernet input, and dispense via whichever output you have selected. Audio Pro C5-A, more lengthily titled ‘Audio Pro AddOn C5-A Wireless Voice-Controlled Speaker’, is a versatile take on the original Addon C5 model, with an increasingly wider universe of connectivity and convenience – combining modern ‘Alexa’ virtual assistant technology with an already-high spec domestic speaker for the trendy home user.
