— a format that includes a subwoofer and a set of three main channels — left, right and centre. This format allows you to achieve more authentic surround sound than in 2.0 and 2.1 systems, and without a significant increase in the cost of the projector; and a subwoofer (built-in or external) provides good bass quality.Show
