The Sony HT-A9 with Bass Module is a 4.1.4 setup with a very unique design. The manufacturer's 360 Spatial Sound Mapping technology offers a fantastic soundstage performance, so your audio seems to fill the room around you. The addition of the SA-SW5 subwoofer helps reproduce a more extended low-bass, too. With its Sound Field Optimization feature turned on, its sound profile is a bit muddy, so vocals and lead instruments are a bit thin. [2]

Figure 1. The Sony HT-A9 Speaker

Figure 1 shows The Sony HT-A9 Home Theater System is made up of four wireless speakers and a control box that plugs into your TV’s HDMI port, with two speakers on either side of your screen, and two behind you on your left and right. While the speakers - which come with gray fabric grilles - connect to each other and the control box wirelessly, they do all need to be plugged into an outlet.

The clever thing about this setup is that the speakers don’t need to be oriented at exactly the same height or even equidistant from one another - the Sound Field Optimization technology will measure the position of each speaker, ensuring the sound is tailored to your room and where they’re placed in relation to each other.
