A FEW THINGS WORTH KNOWING
We usually like to use polyethylene terephthalate glycol (PETG). It has superior damping characteristics compared to polylactic acid (PLA). PETG stands up to the elements better than PLA, should you choose to jam outside in the heat. That said, PLA will do just fine for most indoor listening applications.
The frequency response stays virtually the same between rigid FDM plastics. What changes is the timbre. PETG-CF is more natural with faster mid-bass. PETG, ABS, or ASA work well when you want a bass-heavier presentation. PLA and PLA-CF are extremely stiff and can ring a bit in the vocal region unless you add walls or infill. Use at least two perimeter walls with a 0.6mm nozzle, or three with a 0.4mm nozzle. Double the wall count for front baffles. Minimum 10% infill for cabinets and 15% for baffles.
Passive FDM4, FDM5, FDMGeo and FDMDuo builds need a separate amplifier. Check the power range and impedance on your model’s product page. The FDMDuo Bluetooth build includes its amplifier and battery board. The FDMS8 uses a powered plate amplifier.
Yes. When printed in PETG you can play outdoors without the cabinet softening. We do not recommend direct contact with water or very humid conditions. A garage is fine.
For nearfield and desktop listening, keep the speakers at ear height and toed in toward the listening position. In a living room, give the pair some space from the wall and sit on the center line between them.
