The Advertising campaign is based on the metaphor of ‘depth’, and more specifically, how the Denman Horn’s EQ range is far greater than that of modern day sound devices using heavily compressed sounds. This superior sound depth is shown visually through the brickwork of the room surrounding the device, a more compressed one (headphones) showing less of a frequency range demonstrating barely any visual movement.

The Poster design continues this metaphor further showing multiple planes of ‘depth’.

Below is a projection mapping concept to show how the exhibition might advertise the exhibition internally around The Science Musuem. Not only does it continue the metaphor of depth but would be an effective advert as it appears out of nowhere when a customer walks past, creating surprise and intrigue.
