Sony BRAVIA HT-A9M2 Theater Quad

No, the HT-A9M2 is a standalone system. The four wireless speakers connect directly to a control box, eliminating the need for a separate receiver or a traditional soundbar.

The system features Automatic Sound Field Optimization. It uses built-in microphones to measure your room's layout and speaker placement, then automatically calibrates the audio to ensure a balanced soundstage.

Yes, the speakers are designed for flexibility. You can choose to place them on stands or mount them directly to your wall depending on your room's setup.

Yes, the control box supports HDMI 2.1 features including 4K at 120Hz, Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM), making it a great match for modern gaming consoles.

The system does not include a subwoofer in the box, as the four speakers are designed to handle a wide frequency range. However, you can wirelessly add a compatible Sony subwoofer if you want to enhance the low-end bass performance.

Acoustic Center Sync allows you to connect the system to a compatible Sony BRAVIA TV, which then acts as an additional center channel speaker. This helps align the dialogue more precisely with the action happening on the screen.
