Retro Mini Computer Speakers (Nine Oh Ones)

thingiverse

Here's one for the retro fanboy's. I crafted these mini speakers because I'm utterly captivated by the original Bose 901's, but unfortunately, I don't have enough space in my home to accommodate a full set. So, I decided to create a miniature version for my office instead. These mini speakers are designed specifically to run with drivers from Parts Express: https://www.parts-express.com/dayton-audio-ce-series-ce32a-4-1-1-4-mini-speaker-4-ohm--285-103 To get started, you'll need...9 per speaker - who would have ever guessed that number?! I'll be uploading wire schematics soon; I just haven't had the time to draw them up yet. Next, I'm planning on designing 2 mini mono power amps and a mini Bose DSP. These will be uploaded into another project, with internal components listed below: * 2 x https://www.ebay.com.au/itm/DC-12V-26V-100W-Mono-Channel-TPA3116D2-Digital-Power-Audio-Amplifier-Board-gib/193172478035?hash=item2cf9fa1853:g:1AoAAOSwC2ldr8Pa * 1 x https://www.parts-express.com/dayton-audio-dspb-icp1-in-circuit-programmer-usb--325-132 * 1 x https://www.parts-express.com/dayton-audio-dspb-k-dsp-kernel-board-and-dspb-ke-kernel-dsp-expansion-2-in-3-out--325-1300 * 1 x https://www.parts-express.com/wondom-brb6-bluetooth-v40-aptx--edr-audio-receiver-board-with-35mm-aux-in-and-control-butt--320-3530 I intentionally designed this project to be printed on a SLA photon-based printer, with all parts fitting within the constraints of the Anycubic Photon. For optimal results, I recommend using the new water washable resin from eSun. This stuff cures incredibly fast and is extremely accurate. To get the best results, cure it under lamp only long enough for the surface to stop being sticky, then paint it to protect from over-cure. Here are the settings you'll need for the eSun water washable: * Layer thickness: 0.025 * Layer exposure time: 8 seconds * Base layer curing time: 25-30 seconds * Number of base layers: 4 Once you've run the speaker cable through the pedestal stand, I recommend sealing it up to prevent sound leakage from the sealed speaker chamber. I did this to increase internal chamber size and boost bass depth. Please note that this is a work in progress project, and I'll be uploading changes or fixes as it develops.
