Here is my latest speaker system, it's a set of hi-fi grade speakers designed to be printable on small-bed 3D printers, including the Prusa Mini. It's a sub-woofer and satellite system usable as a 2.1 stereo system, or a home cinema system.

If you like the design or add it to a collection, please hit "Like", to help others find it. ;-)

Frequency response is 35Hz - 20kHz, with the sub-sat crossover at around 135Hz. The subwoofer stands vertically with a 18 x 18 cm footprint, the satellites are 65mm cubes, with stands or a wall mounting bracket. The speakers can be driven by a standard home cinema amplifier, a low cost 2.1 Class D amp, or a DSP based amp with the code provided. The system will play loud but not defending in a 2.1 set-up, you can double up on the satellites if you want more power handling. Either the sub or the satellites can be taken alone and partnered with other speakers with appropriate frequency response.

The sub-woofer acoustic design is based on the highly respected Voxel sub-woofer by renowned speaker designer Paul Carmody, and the satellites are my own design.

It's a bit more complex than previous projects, so I made an Instructable:

Update 2021/12/2: Added printable version of the ND65-PR passive radiator for the satellites. I was able to tune this correctly with an M3*15mm screw and two M3 nuts, your results may vary depending on what TPU you use. More info here:
