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 praise the SB-5000 for its all-new 15-inch driver, 2,000 W Class D amp, and 295 MHz DSP that together deliver pinpoint accuracy, massive low-frequency output, and near-zero resonance. They note the sealed design provides tight, musical bass ideal for reference-level music and home cinema, while also calling out the need for ample power and the unit's substantial weight.
