Review on 🔊 Audio Pro Addon C-SUB: WiFi Powered Wireless 6.5 inch Bass Subwoofer for Studio and Home Theater - White by Luis Jacob

Provides good bass extension for my two C-10s, but requires some fiddling to get it right. Also problems with the volume control. When connected via Wi-Fi, the volume is enough to match my pair of C-10s, but not by much, and the volume rocker on the back doesn't do anything. The volume of the subwoofer can only be controlled via the app. and does not change when the volume of C10a is changed. The subwoofer must be configured separately. When connected via an RCA cable, the subwoofer can produce a significantly higher volume and is controlled by a combination of the volume control on the rear of the subwoofer and the volume of the device controlling the RCA cable. In my case it is C10. When I turn up the volume on the C10, Sub remembers that. AudioPro updated the FW in the C10 in 2020 (a huge improvement), but I didn't test the C-Sub again over WiFi. At the moment I am satisfied with the RCA connection.
