The Yamaha True X Sub 100A is a slim wireless subwoofer built to add low bass to Yamaha's True X sound bar and speaker systems. Its 6.3-inch side-firing cone and 100 W amplifier cover roughly 35 Hz to 100 Hz, and its narrow cabinet fits beside a TV or couch where a boxy sub would not. It is not a standalone sub: it pairs wirelessly with True X components rather than working with any receiver. Owners rate it highly for the extra weight it gives movies and music, though its bass depth and output are modest next to larger subs.

Owners give it strong marks for the bass boost it brings to True X sound bars and for its narrow footprint. Most criticism centers on its limited output and its dependence on Yamaha's ecosystem.
