Build your own Concrete Bluetooth Speaker (how-to)


    • Build your own Concrete Bluetooth Speaker (how-to)

    Today we’ll be building a Bluetooth speaker! Visually it looks fantastic with a lovely wooden front and a concrete outer shell. This concrete not only looks great, but it helps audio quality too, as the sound produced by the speaker is very solid and confident due to the lack of resonance. Plenty of techniques will be used for this project, so sit back and enjoy!
