prusaprinters

<p>This is an open source full range speaker driver called FD51-4PM. This Polymaker edition was supported by Polymaker and is a more advanced version of FD51-4OS.</p> <p>Where 4OS is easier to print and allows for a lot of tolerance, 4PM does not, thanks to the consistency of Polymaker's filaments.</p> <p>Along with a more advanced magnet motor and the lighter Polywood filament, this driver is 4.7dB louder than 4OS. The new suspension system allows it to also exceed 4OS with bass response and extension.</p> <p>These improvements mean it is easier to damage when over driven. These are built for a 3W to 5W power rating. There improved efficiency suits them well for battery based products.</p> <h3>Print instructions</h3><p>Cone to be printed in Vase mode @ 0.15mm layer height.</p> <p>Surround &amp; Spider to be printed @ 0.10mm or 0.15mm layer heights.</p> <p>Chassis and cap can be printed up to 0.25mm layers with a 0.4mm nozzle but suggested 0.15mm.</p>
