Sony announced two entirely new high-end home theater products today: The four-speaker HT-A9 home theater system and a new flagship soundbar, the HT-7000A. The audio manufacturer also announced two wireless subwoofers that can add deeper bass to either product, and wireless rear speakers that can supplement the soundbar. The Sony HT-A9 home theater system ($1,800) consists of a control box with a LAN port and HDMI in and out, along with four cylindrical, wireless, self-powered speakers. Each speaker has two built-in microphones that measure the speaker's relative height and position in the room. Sony's 360 Spatial Sound and Sound Field Optimization technology then creates up to 12 phantom speakers by synthesizing sound waves based on positional information.
