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.
Professional reviewers highlight the Sub 4's deep 25 Hz low-frequency response with force-canceling dual woofers, automatic Trueplay room-acoustic tuning and app-adjustable EQ deliver optimized bass for any space. Flexible placement allows vertical or horizontal orientation, even under furniture, for hidden installs.
