FDM5 Loudspeakers

Developed in the summer of 2023, these 3D printed bookshelf speakers are our first attempt at properly meshing 3D printing and audio.

We believe that we hit the mark!

FDM5 Loudspeakers throw out an impressively wide soundstage and boast a warm mid-bass response. The speakers are good clean fun, but they also know how to get down and dirty. Carefully tuned to reduce listening fatigue, you'll want to enjoy these speakers over and over with their sugary sweet top end and rich lows.
