Mini Sub-woofer

thingiverse

Build this low cost, high output, desktop subwoofer for Hi-Fi music listening or for PC gaming. It just needs a few off the shelf parts and a 3d printer. Update: Please note that I've added a bezel for a cleaner and more modern design and I've increased the cabinet volume to match exactly what Peerless recommends for a sealed enclosure. This means the infill has been drastically reduced and the shell now has a thickness of 8 to 10 mm (excpet for the baffle) and the cabinet is 13mm longer. I can't hear any differences, but the math states that the volume at very low frequencies should decay at a slightly slower rate than the previous model. If you have already printed the previous version, I would recommend you just print the bezel. All the dimensions and parts are the same as the previous version except for the slightly longer cabinet. I have both cabinets posted for download just in case someone prefers the older model. Technically, this is now V2 of this project. Background: I've been working from home for over a year and felt my PC desktop audio system needed an upgrade. This sub-woofer is based on the Peerless Tymphany SDS-135F25CP02-04 5.25 inch driver which costs < $30. I 3d printed the cabinet using PETG. I'm amazed at how good this sounds and feels. I created a [short video](https://youtu.be/MwvT5tFlLcU) in case others are interested.
