Retro Mini Computer Speakers (Nine Oh Ones) by CompuGlobalHyperMegaNet

Last crawled date: 4 years ago

Here's one for the retro fanboy's.
I created these because I love the original Bose 901's, but I don't have room in my house to put a set, so I made a mini set for office instead.
These are designed to run these drivers from parts express: https://www.parts-express.com/dayton-audio-ce-series-ce32a-4-1-1-4-mini-speaker-4-ohm--285-103
You will need....9 per speaker, who would have guessed that!
I will upload wire schematics soon, just haven't had time to draw that up yet.
I will be designing 2 mini mono power amps and a mini Bose DSP soon, those will be uploaded into another project, internal components listed below:

I designed this entire project to be printed on a SLA photon based printer, all parts will fit in the constraints of the Anycubic Photon.
I recommend trying the new water washable resin from eSun, this stuff cures really fast, and is really accurate, I recommend only curing under lamp long enough for the surface to stop being sticky, then paint it to protect from over cure.
Setting for the eSun water washable:
0.025 per layer
8 second layer exposure
25 to 30 seconds for base layers
4 base layers
I also recommend once running the speaker cable through the pedestal stand, to seal it up as the stand is part of the sealed speaker chamber, I did this to increase the internal chamber size to help increase base depth.
Please note, this is work in progress, I will upload changes or fixes as the project develops
