After sketching, I decided to push development further with concepts 1, 3, and 5. Below is an exploration of speaker shapes made of concept 1. 

Introduction to 3D Modeling

The form I landed on was an organic, bulbous shape with the idea of "bites" being taken out and sound being push out form the sides. The negative space creates a push and pull of the form and different proportions of this idea are used within each object. What was successful about the speakers is that they looked like brother and sister, but not twins. They had the same general shaped mirrored but different placements of colors and split lines.
