The idea was to make a 2D video in After Effects as an introductory segment utilising the style of 1950’s videographer Saul Bass depicting two choices in HiFi :- you can either take the subwoofer route with your HiFi or not use one at all, in which case you go on a different journey. I made the subwoofer in 3D in blender and then incorporated it into the 2D scene and with the 50’s style music and sound effects and diagrammatic transitions, the end result is very effective.
