Fastidious is a 3.3L vented bookshelf cabinet you can print on a typical Prusa i3 based 3D Printer. Build volume required is 200x180x150mm. This is the biggest launch model and helps extract the best out of FD61, giving good bass extension and sound pressure output.
Suggested print material is either PLA or PETG. On a 0.4mm nozzle this will take a long time, so I suggest a 0.8mm nozzle and 0.5mm layers.
Frequency response with FD61 is 55<16,000Hz with a power handling within the default Xmax of 2.5W.
