3D Printed Bluetooth Speaker with Multi-Directional Stereo Sound

cults3d

This speaker boasts four 1.5-inch drivers, each situated at a 90-degree angle to its counterparts, forming two left channels and two right channels. As a result, the speaker delivers a stereo sound that remains consistent regardless of listening direction, effectively replicating a full 360-degree stereo sound. The speaker's design also features two passive radiators confined within separate enclosures within the speaker itself.
