The sound effects in this classic stress the power limits of your sound system's subwoofer(s). Many scenes feature low, floor and soul-shaking rumbles that virtually renders the need for deep diving to have an ocean-good time unnecessary. Together with your surround speakers, all channels are effectively used to fully submerge every listener into the moment when bloodthirsty, savage sharks preying on a team of researchers. Every predator movement and squelch is clearly distinctive through the surround channels, making this movie one of the most nail-biting shark-related movies that still hold out today.
