Speaker Enclosure for 4" Driver

thingiverse

With this Covid thing still lingering and keeping us confined indoors, I decided to tackle another Speaker design. This one should fit any standard 4-inch driver perfectly. The design accommodates a driver with an outside diameter of 11.5 centimeters and a cutout of 9.5 centimeters. You can install a female RCA plug in the rear for easy wiring. This design is an open type, which I won't attempt to justify through audio science - so don't even ask me to crunch the numbers on the ports. I've already tested it with one of my spare drivers and I'm pleased to say the sound isn't bad at all. I plan to use this design as a starting point for something similar to my modular sound bar, allowing you to print multiple enclosures that can be connected together to form a larger unit. I printed the enclosure upside down, which means you'll need to add supports. As an experiment, I reduced the layer height to 1.5 millimeters. Be prepared for a long wait - the print time was over 24 hours at 6 centimeters per second with 20% infill, so patience is essential.
