To get a better grip of what shapes and expressions that attracted potential customers, I created some abstract forms. I then made a quick survey to check which ones that were most popular. The winners was Form 3 and Form 4.

After the survey I tried to combine the two most popular shapes into a loudspeaker. I was not that pleased with the result, so I went back to the drawing board.

A lot of people asked for smaller speakers than the one my previous design was based on. So I decided to make a quick test model to see if it was possible to remove one of the midrange elements. In order to get the most accurate result I also built a new case for the original speaker. I didn't want the different material properties between aluminum and chipboard to affect the sound.
Neither I nor the other people I asked to listen to my speakers could hear any significant difference between them. i therefore decided to make a speaker with only one 4" midrange element and the 4" tweeter.

I tried to take the shapes I liked in my precious design and improve them for a two-element speaker. After reading some interior design magazines I also made a version with sharper lines.
To decide which one to finalize, I made another quick survey. The winner was the upper design, which also happened to be my personal favorite.

I wasn't completely satisfied with the shape I came up with earlier, so I tried some other variations of it.

After I had drawn up a shape that I liked, I focused on creating a protection for the speaker elements. I wanted the protection to give something extra to the design. So that the speaker had slightly different expressions if the protection was mounted or not.

To create the subwoofer I extracted the key elements of the satellite speaker; The two circles and the different roundness of the corners. In order to get the inner volume of the enclosure I designed it in SolidWorks.

The stand for the satellite speakers. They let you adjust the angle of the speakers, and they also have a smart fastener for the power-cable.
Designed in SolidWorks, rendered in KeyShot.

I didn't think the fiberglass mesh on the speaker elements looked very professional or attractive, so I wanted to give them a new look. I tried some different combinations of colors fund in the BK Audio brand. My final decision fell upon the bottom right option, with a small blue line extracted from the lightning bolt in the BK Audio logo.

Both the satellite speaker and the subwoofer have fabric protective fronts. They are attached with magnets, leaving no marks when removed.

In order to pass this course, and to have something more substantial to show BK Audio, I had to make a model of the speakers. i decided to make a functional model in scale 1:1.

The finished model, which actually had a pretty good sound.
