    Default FINISHED! Apple themed Overnight Sensation MTM

    Hello everyone. I posted my original concept for a 2.1 computer, desktop speaker system on a few other forums. Since all of the parts I am using came from PE, and many of the people I have been talking to are also in this forum I thought this would be the best place to start my project log.

    (Click here to skip to the finished pictures)

    Project Goals:

    - Build a pair of desktop speakers with an Apple styling to match my computer hardware. (think aluminum, glass, silver, black)

    - Build a subwoofer

    - Hide/integrate as much of the hardware, wires etc as I can to give a clean finished look.

    So my plan is to start with the speakers then move on to the subwoofer. The general plan is to use this amp.
    Dayton DTA-100 Class-T Digital Amplifier 50 WPC
    to power 2 desktop speakers and this plate amp
    Bash 300W Digital Subwoofer Amplifier
    to power two sub woofers. Heres the catch. The subwoofers will be built into the underside of the desk. One on each side with the amps in the middle. The amp controls will be rewired and relocated to a recessed plate in the front of the desk allowing easy access to sub levels etc. Here is a picture of what the desk *might* look like inside...

    So the desk and the subs are phase 2... phase 1 is the speakers... Once I have finished speakers I can work on the desk and subs.

    The design I came up with is very similar to Pauls "Overnight Sensation MTM" design in terms of size, layout, and driver selection. As this is my first home speaker build, I will be using his specs in terms of drivers, box size, and crossovers.

    I will be modifying the design slightly. The drivers will be moved up higher in the box to make room for forward facing porting. The overall boxes will have rounded edges on the tops and bottoms, painted silver. The front and back will have black painted plexiglass to give the glossy black appearance. Here is a rendering of what I hope to create (note, the speaker surrounds, tweeters, and porting are shown in dark gray to show contrast with the black plexiglass on the front)

    Here is a detail of how the front baffle would be cut to accommodate the plexiglass inlay.

    My order has been placed with PE and I'm sure it will be on its way shortly. I'm looking forward to this build.

    Here is a list of what I ordered from PE exactly.
