This is a 3D printed back load horn bluetooth speaker project.
You will need two 1inch 3W full range speakers and bluetooth amp.
An 1 inch speaker is very small but it will make very big sound because it is mounted on back load horn body.
Especially it's sound is so natural because it use only one speaker per channel so it is not needed coils and capacitors network system which will reduce sound quality.
Usually back load horn speaker system is very expensive.
But now, enjoy extreme sound quality with cheap price using your 3D printer!
