Redesign an object: 

I went to RISD second life store and bought a squarish speaker. It only has a main speaker driver (Actually it also has a tiny driver below but that is a fake one so I didn't count). Single speaker driver and boxy structure limit its efficiency in spreading sound waves. My goal is to change its structure to get a better sound performance and a more appealing look.

The major change is replacing the old sealed enclosure with a bass reflex enclosure. A bass reflex system (also known as a ported, vented box or reflex port) is a type of speaker enclosures that uses a port or vent cut into the cabinet and a section of tubing or pipe affixed to the port. This port enables the sound from the rear side of the diaphragm to increase the efficiency of the system at low frequencies as compared to a typical sealed- or closed-box loudspeaker. New design's round shape also makes sound waves spread and reflect more evenly to achieve a better sound quality.
