Professional commentary highlights the Sub's ability to produce deep, rich bass with zero cabinet buzz, thanks to its force-canceling drivers and digital amplification. Reviewers note its seamless integration with the Sonos ecosystem, automatic Trueplay tuning, and premium gloss finish, while pointing out the lack of Bluetooth/AirPlay and the need for iOS for calibration.

Professional reviewers commend the HT/1205 MKII for delivering cinema-grade bass impact from a surprisingly compact enclosure, citing its powerful MOSFET-driven Class D amp and refined chassis as key strengths. They highlight its ability to rival much more expensive subwoofers while noting the added weight and the need for an optional wireless module as minor drawbacks.
