Short answer: the Edifier R1280DB. It ranks #35 of 64 powered bookshelf speakers by sound quality at $159.98; the Sigberg Audio SBS.1 ranks #37 and costs $2500, so there is not much of a tradeoff to weigh.
What the Edifier R1280DB offers: Same drivers and cabinet as the ASR-measured Edifier R1280T (identical 4” woofer, same 4.9kg enclosure) plus Bluetooth and digital optical/coax inputs the R1280T doesn’t have. ASR’s measurements of that shared platform found the woofer handled a demanding bass-heavy track without bottoming out or audible distortion, and distortion stayed low and inaudible at a normal 86dB SPL listening level. Built-in remote and bass/treble tone controls, no separate preamp needed. Watch for: Shares the R1280T’s jagged on-axis response rather than a neutral one, with a woofer resonance around 5kHz and a tweeter peak near 10kHz that also show up in the directivity data. The reviewer’s raw impression of that platform was “a bit bass heavy and after a track or two, somewhat bright,” and recommends EQ correction; vertical listening window is narrow, so the tweeter needs to be angled toward the ears. Not quite as neutral sounding as the Edifier MR4.
What the Sigberg Audio SBS.1 offers: Its 6.26 Spinorama preference score with a perfect subwoofer is the appropriate bass-normalized result because the SBS.1 is designed as a system with companion subwoofers, not for standalone use. That score exceeds the Manta’s 5.91, supported by better on-axis linearity and in-room smoothness above the subwoofer range. Distinctive 4-way coaxial design with dual 5.5” midbass drivers flanking a coincident 1” tweeter for time-aligned output. Active 3-channel Hypex nCore Class D amplification (350W per speaker) with a 9-band parametric EQ and factory presets. Watch for: Its 6.26 preference score with a perfect subwoofer trails the SBS Gen 2’s 6.74, and it has the widest listening-window deviation of the three Sigberg systems. Discontinued and sold out, replaced by the SBS Gen 2.
Buy the Edifier R1280DB. It ranks higher for sound quality than the Sigberg Audio SBS.1 and costs less, so there is no real case for the other one.
