Our Verdict
Sony HT-A9
Sony HT-A9 with Bass Module
The Sony HT-A9 with Bass Module is better than the standalone Sony HT-A9. With the addition of a dedicated subwoofer, the full setup can reproduce a more extended low-bass. This also improves its surround and Atmos performances, meaning you can feel more thump and rumble in action-packed movies. That said, the subwoofer does add some compression at max volume compared to the standalone bar.
