I finished designing the Apple themed desktop speakers. They will be made from 3/4 MDF and plexiglass. I have already started working on the crossovers and specific design details. Here is a rendering of the speakers themselves.
And here is a rendering of them on a desk with a Apple 27" iMac for size reference. This is fairly close to my intended desktop setup.

I have been working on my 2.1 desktop speaker design. Starting first with the speakers then moving on to the sub. My goal is to make a pair of desktop speakers that sound much better than your standard logitech etc "computer" speakers you can buy at your local electronics store. I also want it to have a very Apple design to it so that they better match my MacBook and Apple accessories. With that in mind it will look similar to the iMacs display, rounded aluminum corners, glossy black front. Clearly, aluminum and glass are not the best speaker building materials so I will be using paint to get the aluminum color and plexiglass in place of real glass.
The design is based on a proven speaker design, the "Overnight Sensation MTM" Which I am modifying slightly to meet my goals. Here is a picture of the current design.
The overall dimensions (WxHxD) are 6"x16"x8.5", two 4" aluminum cone drivers will provide mids and lows, a 1" tweeter (shown mounted between the 4" drivers) will provide the highs. The two gray circles at the bottom indicate the twin porting necessary for proper bass extension. Speaker brackets, tweeters, and porting are shown in dark gray to show contrast. These are all black in reality. A glossy black painted piece of plexiglass will be added to the front to cover most of the mounting holes etc and will be flush with the silver edges of the box.
So that is where the design stands right now. Still a few minor details to work out in the design but the parts are all planned out so it looks like I might be able to put these together faster than I thought. More updates when I get some of the parts in or as I add more details to the design.
