For this modeling bootcamp, model your computer speakers.
For maximum realism and accuracy, try not to take any shortcuts. If there're two seperate pieces, then by all means, make them two seperate pieces. Bevel all of your edges and don't make excuses for it not looking awesome in the untextured form. I've been told that although texturing can make a model look really good, the best models look great even when untextured. Just so it's clear, don't texture this model at this point, you can later but for the sake of this modeling bootcamp it really doesn't help.
Optional: For some level of uniformity, I suggest that our lighting be similar.
My suggestion:
-From the default choreography remove all of the lights.
-Add a skylight of your choosing. If you have skycast 2, that's great, if not Yves' skylights are great and so are Jeff's fully customizable ones (which can be found here: http://www.shipbrook.com/jeff/animas/skylight/, in most cases the default settings work great. And full instructions for how to use it are here: http://www.shipbrook.com/jeff/animas/skyli...structions.html, it sounds complicated, it makes sense after you've done it once)
-Add a single spotlight so you have shadows where you want them.
-In the camera properties change the background from blue to something greyscale, from black to white.
Good luck. I can't wait to see what you make. Remember to include a wireframe in addition to any renders.
