Mini Subwoofer

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 in case others are interested.  Please note that the video does not show the bezel that was created after the video was made.

Print Settings:

• No rafts
• No supports
• 45% Infill
• Filament material:  PETG or PLA

Notes:

In order to deal with the stress the driver will create and to sound as it should, print with:

• 4mm walls.
• 40% to 50% infill. I used 45% cubic.
• PETG, PLA should work as well.
• If you can, slow down the fan a little to make sure the filament bonds very well. If using PETG as I did, turn off the cooling fan. Another option is to extrude at a slightly higher temperature.

Parts Needed:

• 1 Peerless Tymphany SDS-135F25CP02-04 5.25 inch Sub-woofer
• 1 set Gold Binding Post Banana Jack Pair Extra Long Shaft with Solder Tabs
• 1 Acousta-Stuf Polyfill 1 lb. Bag Speaker Cabinet Sound Damping Material, you will use much less than 1 lb
• 1 Parts Express Cast Frame #8-32 Speaker Mounting Kit
• Blu-Tack (optional) to improve the seal from driver to baffle.

To connect the binding posts to the driver:

• Speaker wire
• Crimp on connectors or
• Soldering iron and solder
