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 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. By adding proper multi-room features to its fantastic Addon speakers, Audio Pro has answered many people’s prayers. The C3, C5, and C10 are industry-leading speakers in their own category. Class-leading C5 speakers were well accepted by the public and audio enthusiasts. It has two siblings, C3 is the smaller and portable one, C10 is the biggest of the bunch. In this review, we will talk about the multiroom lineup and share our verdict after testing the audio products. Speakers

But it’s important to point out the Audio Pro is far from the most limited multi-room app out there, and its occasional bug and rudimentary nature is forgivable when you consider the price and sound quality of the speakers it's controlling. For the ultimate in speaker control, each drive unit is driven by a dedicated digital amplifier. With 15 watts for the bass unit and 5 watts to each tweeter, a total power output of 25 watts is on hand to give generous, room-filling sound. The unique boom-box style design is easily recognizable from distance. One more thing which is recognizable is the unparalleled sound quality of these speakers. The lineup which starts with ‘C’ is the wifi-enabled version and the ‘T’ models are Bluetooth only. The Audio Pro Addon C3 vs C5 vs C10 are almost similar in appearance except for their size, while the Addon C5A has a volume indicator and a pair of microphones on its head for use with Alexa voice assistant. The increased power and driver and cabinet size predictably ushers a grander performance each step you take up the chain, with the Addon C10 particularly able to rattle trinkets from the mantelpiece or twist our insides with its low-end authority.They time with metronomic precision, but temper it with the kind of dynamic sense that captures rhythmic emphasis nicely. And that dynamic expression is a strong positive over the speakers’ entire performance, able to reflect lavish shifts and subtle nuance alike. It simply does everything right, and without fuss.

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. The sound of both C5 and C10 felt very self-assured. Every song or podcast was almost exactly like it should sound. The power usage is double on the C10 which is normal for its larger footprint and heavy sound output. There was a good bass response from both. The bigger C10 weighs more and also performs louder than C5. In a small room, the C5 will perform fine but outside it might struggle. The app is good too, it’s easy and fast to set up. You can also buy 2 or more products and link them for the multiroom feature. It will enable you to play all the devices at the same time.Increasing the size of speakers even further, both of these models are the largest speaker among their brands. When you move from T3 to C3, the dimensions are similar, and they all have the sophisticated interface touches we’ve come to expect from Audio Pro. For a wireless speaker at this price, the textured surfaces and embossed leather carry handle are rather sophisticated.

The Audio Pro AddOn C3: Small size, mighty sound

At a single glance, Audio Pro speakers look very bulky and spacious that serves as a huge turnoff. However, if you love your speakers to have that traditional touch like Audio Pro C5A, looks won’t be an issue for you. Small in size, big on sound, the C3 delivers astonishing audio quality for its size. The plan for Audio Pro’s Addon wireless speaker line has been straightforward. Finish the regular Bluetooth models’ architecture and sound quality, then release multi-room versions of the same speakers. It might be simple but it’s very effective. As part of the C-Series, you can link together several speakers for effortless, multi-room sound. Controlled via a dedicated app, setting a multi-speaker system up around your home is easy. Thanks to Internet connection via Wi-Fi, there’s no need for any wires between rooms, either. Even more impressively, you can incorporate old Bluetooth-only Addon speakers*, by using a C3, C5 or C10 as a parent speaker. (*Audio Pro ADDON Link 1 required for function support).

They keep time with metronomic precision, but with a harmonic sense that nicely catches rhythmic focus. And the speakers’ expressive speech is a strong plus during their entire show, able to convey extravagant changes as well as delicate complexity. It actually does everything correctly and efficiently.
