Not at all the portable speakers, these two are meant for throwing backyard parties and using them on a large scale. It fits our Addon T3 like a glove, which is of little surprise – but even hooking it up to feed Spotify into our reference hi-fi system doesn’t hold the performance back, despite the inherent limitations. Thankfully, some are cool enough to make the change and still garner respect, as Audio Pro has done with its A10 wireless speaker.

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. The dimensions are identical as you jump from T3 to C3, and they also share the sophisticated design touches we’ve come to appreciate from Audio Pro. It doesn’t have quite the unwavering focus, nor the sheer weight in the low end, but we can move around our test room and still be treated to the same high quality sound. The Swedish firm has since released a sequel, the sensibly named Addon C10 MkII, which delivers on its promised enhanced functionality, sound quality and design to now also become a multiple Award-winner. The original has undergone a few tweaks, rather than wholesale change: it keeps its pair of 2cm tweeters, split by a 9cm woofer, as well as its familiar boombox-style chassis, but carries a redesigned reflex port to the rear for optimised bass response.

The A10 is as comfortable rendering those wavering intensities as it is throwing its weight behind grand shifts and drawing back completely with a sudden break. It makes it much easier to appreciate not only the detail on offer here but also the space in the mix that helps the Addon T3+ avoid becoming crowded or muddled when it is fed denser recordings. Thanks to the physical design of its speakers, Audio Pro has always managed to give a great deal of body to its sound, and that is still the case. Moreover, you can use it as a wired as well as wireless speaker with the help of Wifi, Bluetooth, and Audio Pro Multiroom app.

The bookshelf A28 and floor-standing A38 build on the success of their A26 and A36 predecessors, boasting improved performance with a new streaming chipset and further sonic fine-tuning. However, if you love your speakers to have that traditional touch like Audio Pro C5A, looks won’t be an issue for you.For those who own the previous C10, Audio Pro says the C10 MkII can be used as the master speaker with the older versionfollowing a firmware update. One thing for Alexa users to note is that Alexa voice control integration, which works well on the C10, is nowhere to be found on the MkII model. It’s busier but neatly laid out, with a new source selector button and LED indicator for Bluetooth, wi-fi and its 3. Using it outdoors for grilling, in your country home, or somewhere else where you don’t have access to the internet. From the front it looks almost identical – the 9cm woofer splitting a pair of 75mm tweeters in what we’ve affectionately dubbed Audio Pro’s ‘koala’ configuration (the Coal Black finish doesn’t show the furry association quite as well as Arctic White or Storm Grey).
