FD51-4OS (Open Source Edition)

Current Status: Complete!

Motor: Sparkler (Legacy)

FD51-4OS is the first 3D printed speaker driver released by Polymate3D and was produced as an easy to print and assemble driver, with a focus on showing the potential of this method of production. It took a lot of what was learnt from the 3 years of development prior on FD61. A highly complex driver which never came to be after a failed kickstarter but a major part of the Polymate3D history.
