The Choprical Fish: a Human Powered Party Bike

Step 11 Create subwoofer retrorockets and midrange 'eyes'.

In the design for the cabinet, I wanted the subwoofers to emerge from the form like retrorockets. I saw this as a way to add significant volume to my resonating enclosure, without making it look like one big bubble. The other thing it accomplished was angling the sound forward and out, so that the ears of the rider are within the dispersion cone of the speakers.

Similarly the midrange 'eyes' increase the volume of the overall cabinet slightly and angle the sound forward. I like the eyes, because they play into the tropical fish theme of this cabinet. It's not a literal reference, but the end version of the cabinet looks a bit like a tropical fish. It fits with my mission of getting more people on bikes --> less global warming --> more coral reefs and tropical fish mission.

The process for creating the retrorockets was similar to the process of making the main form. I sculpted foam until I liked my shape and then glassed it. In this case I had some assistance from Wen, who was quite skillful wetting out the fiberglass.
