Lyngdorf SB-75 Passive Stereo Soundbar Designed for Wall-Mounted Hi-Fi Systems

The passive architecture also opens up interesting system‑matching discussions. Without onboard amplification or DSP correction, the SB‑75 relies on electrical damping and current delivery from the chosen amplifier to control its multiple parallel low‑frequency drivers. This places real importance on amplifier stability into complex loads—an angle often ignored with active soundbars. From a purist perspective, this is a deliberate trade‑off: fewer internal compromises, but greater responsibility on system design. It also means crossover implementation remains entirely analog, avoiding latency and processing artifacts that can creep into digitally managed bars, especially in stereo listening.

Visually understated, the SB‑75 leans into architectural integration rather than visual statement, yet the availability of custom dimensions hints at its intended role in high‑end cinema installations where symmetry and screen alignment matter as much as tonal balance. Compared to mainstream soundbars chasing virtual surround algorithms, Lyngdorf’s approach reads almost contrarian—prioritizing phase coherence, mechanical rigidity, and predictable acoustic behavior. For listeners who value stereo image stability and timbral consistency over feature lists, the SB‑75 positions itself closer to traditional loudspeaker design than to the soundbar category it nominally occupies.
