Bluetooth Speaker (mono or stereo)

A set of powered 4" bluetooth speakers that look stylish and modern while sounding great for the price!

The enclosure has hollow walls that are designed to be filled with plaster of paris. Simply mix, fill the speaker housing through the fill port in the back and allow the plaster to fully cure for a rock-solid and hefty enclosure with excellent acoustic properties.

Works especially well when adding a small amount of PVA glue to the mix, see here for more information:

You can choose between printing just one mono-speaker (in this case, print only the active backplate with the amp mount) or a pair of 2.0 stereo speakers, by printing both backplates and all other parts twice. 

I recomment printing the enclosure in Wood PLA, it looks by far the best of any filament I've tried and pairs beautifully with the heft of the plaster-filled speakers once they're done.

You may also need some speaker wire to connect the speakers, if you're printing both. 
Feel free to download the STEP files and modify them if you want to change the amp or the drivers for different ones.
