”For sound quality at this price, this system remains unbeatable”. ’What Hi-Fi?’ 2020 award-winner.

Wireless auto connect

If you’ve got an Audio Pro multi-room system, then this is the way to add effortless bass. The wireless link quickly locates the nearest component – such as an ADDON C5 or C10 – and boosts the bass from that unit. If you prefer, a wired connection is also available.

Feel the sound
Adding a C-SUB takes the sound to the next level by delivering a bass that’s not just deep but also punchy. The long throw woofer unit is backed up by passive radiators and a dedicated 200 watt, digital amplifier for the tightest grip on the sound.

Compact style
Measuring just 23cm in each direction, the C-SUB is a perfect cube of compact style. Smaller than most subs and also available in colours that match other ADDON components, this is one of the most stylish subwoofers out there.
