5.25" Subwoofer Enclorure With 6.5" Passive Radiator

Last crawled date: 4 years, 2 months ago

Passive/active subwoofer enclosure. (work in progress). The IO Panel is made to be replacable to leave some flexibility. Rather than just a passive, it can be made with an internal amplifier (as long as it fits) by simply swapping out the io panel with mounting and holes for volume knobs etc. Make sure you print it strong enough, 3 perimeters and 20% at least.
Printed parts:
main enclosure
Top
Feet
Feet pins
Passive radiator
IO Plate
Other parts:
14xM4 screws (everyone got laying around)
2xM4 nuts (everyone got laying around)
Wires from terminal to subwoofer (everyone got laying around)
Subwoofer driver (I salvaged one from Logitech PC speakers with defective PSU)
6.5" Foam surround (this red one: https://www.ebay.com/itm/313014806133)optional Amplifier with LPF (this one: https://www.ebay.com/itm/312964648437)
(as an external amp, it will not fit in the current IO)
Assembly:
Pretty straight forward. The top is glued on, the feet should be a press-fit with the included pins, the passive radiator needs to be glued to the surround which is then glued to the enclosure. The terminals are just 2xM4 screws and nuts and the panel is held in by 12xM4 screws.
Other:
It is designed with 12mm thick walls so it can be made out of MDF as well. The walls are also seperate components which makes it easy to print out plans for making it in MDF.
I will probably make a V2 in the future with a better assembly than just glue and add diffrent IO Panels for use with internal amps and batteries that can easily just be swapped out for diffrent use cases, but for now I will just leave it like this. If you want to make any changes to it, I can provede the fusion 360 project file.
