Portable Bass Shelf Speaker w/ Bluetooth (Tang Band + Dayton)

Version 2.0 files available!
Key differences:

• M3 mounting points for a more sleek printed handle at the top of the speaker

• Barrel jack for power and mounting points for a battery holder at the back

• JAB4 now mounts to the access panel for easier wiring

• Woofer is fastened using heat inserts from the inside: Sub grill started to warp when using it to secure the woofer to it.

• Use of countersunk screws

• Improved internal cable routing

Bluetooth Backpack Speaker

I remodeled the entire enclosure from HexiBase and added a small extension at the front to allow the speaker grills to sit flush with the port. I also added an access panel and a small control panel with potentiometers, a on-off switch and a connector to program the DSP.

It is designed to work with a Wondom/Sure JAB4 4x30W DSP amplifier but can be fitted with different amplifiers.

Additionally a Parkside Battery can be mounted to the back.

There are two test models for you to make sure the tolerances fit your printer.

I printed mine with 4 outer walls and 30% infill, which consumed about 2.5kg of PETG in total.

For the assembly you will need a whole lot of M3 heat inserts and M3 screws (and some M4 ones to secure the woofer). I'm using heat inserts with a length of 5.7 and a diameter of 4.5mm. The holes for those are 6mm deep and 4mm wide.

I used a laser to cut the gaskets for the woofer and access panel out of 1mm thick self-adhesive foam board.

Note: For this speaker to sound properly, you'll have to edit the settings of the DSP. You are going to need a in-circuit programmer for that (i.e. Wondom ICP1).

I strongly recommend that you watch HexiBase's video first:
