Speaker Enclosure for 4" Driver

With this Covid thing hanging around and causing us not being allowed to venture outside for pretty much anything I decided to do another Speaker design. This one should fit pretty much any standard 4" driver. The design fits a driver with an outside diameter of 11.5cm and cutout of 9.5cm. You can mount a female RCA plug in the rear for the wiring

This design is an open type (which as usual is not based on any audio science whatsoever, so don't ask me for the calculations of the ports). I have put one of the drivers in I had laying around and I have to say, the sound is not half bad.

I will be using this design as the base for something similar to my modular sound bar allowing you to print multiple enclosures that can be attached together to form a larger unit.

I have printed the enclosure "face down" and yes, for this one you will need supports. As an experiment I reduced the layer height to 1.5mm. Print time was well over 24 hours at 6cm a second with 20% infill so you wil
