      3D Printed Bluetooth Speaker with Multi-Directional Stereo Sound

      This speaker features four 1.5inch drivers at a 90-degree angle to each other, two left channels and two right channels, this way the speaker will produce a stereo sound no matter the direction you listen from, consequently emulating a 360-degree stereo sound.

      The speaker also features two passive radiators confined to two separate enclosures inside the speaker.
