About the SB75
The Lyngdorf Audio SB-75 is a passive stereo soundbar designed to deliver the performance of a conventional left-and-right loudspeaker pair in a single wall-mounted enclosure. It contains two independent 2-way speaker systems, with separate terminals for the left and right channels. The closed, internally reinforced MDF cabinet is designed for on-wall placement beneath large 75- or 77-inch displays. It requires an external stereo amplifier; it has no built-in amplification, DAC, wireless connectivity, streaming functionality, or subwoofer output. The manufacturer lists the SB-75 as a current product rather than under its discontinued-products section.
