LittleJet! Desktop Speakers

What LittleJet! are?!

Hello makers, here's Davide, and today I would like to share with you all, my new designs based on this project: https://hackaday.io/project/168919-3d-printed-bluetooth-speakers-littlejet

You can read about it here: https://hackaday.com/2020/05/14/a-transmission-line-speaker-with-the-design-work-to-back-it-up/

Since acoustical engineering is the same in this “desktop version”, if you are curious about it, I invite you to check the links above.
 

The goal

“LittleJet! Bluetooth version” are more difficult to build and it would cost more, then I designed this “desktop version” so you can build them cheaply and easily.

What do you need (BOM)

• x2 - Peerless by Tymphany TC6FD00-04 2" Full Range Woofer
• x2 - RCA panel jack
• x2 - Inductance 1.05mH or close value
• x2 - Resistor 3.7Ohm or 4Ohm (from 3W are good enough)
• DC panel plug
• This amplifier module here (non-affiliated link)
• 19v - 4A Power supply
• Stuffing material (polyester material)
• 3D print all the files once

How to build

A video worth more than 1000 words, so I prepared a video to show how to build them, here it is:
