This DIY Subwoofer Project Build shows that it is truly possible to make a sub that looks (and probably performs) better than lots of the stuff you would find in your local electronics shop. The use of leather and high gloss plastic panels really add to the high end finished look of the speaker.

"The box itself will be built of MDF board. I chose MDF because I can get it for cheap and it’s easy material to work with. I’ll be using dark grey leather and black highly reflective acrylic as finishes. Subwoofers are NOT built in random boxes and hoping it will sound good. I use a progam called WinISD to make the plan. It’s a program where you input the parameters of the subwoofer driver and it will simulate how different box designs work with your driver and amplifier. Different drivers work best in different type of enclosures."
