Sennheiser AMBEO Soundbar Plus vs Sony BRAVIA Theatre Bar 9 Soundbar

The Sony BRAVIA Theatre Bar 9 is the better pick for most people: 13 drivers, side- and up-firing speakers and 585 W give it more real output and a wider soundstage than the Sennheiser's single-unit design. The Sennheiser AMBEO Soundbar Plus counters with AMBEO virtualization, room self-calibration and built-in dual 4-inch subwoofers that reach down to 38Hz, so it delivers deep bass without a separate sub. Owners praise the Sennheiser's room-filling effect but note virtual surround is less precise than physical speakers; the Sony's extra drivers and higher power make it the stronger choice for larger rooms and serious movie use.

• Choose the Sennheiser AMBEO Soundbar Plus if you want one self-contained bar with built-in subwoofers, automatic room calibration and AMBEO virtualization, and you value bass depth over raw driver count.
• Choose the Sony BRAVIA Theatre Bar 9 if you want the most drivers and power in a single bar, with side-firing and up-firing speakers for a wider, more physical surround stage.
