Speaker Enclosure with baffles for 4" Speaker needs full support which can be a pain to remove. Takes almost a kilo of filament and is 160mm high. My printer has weak, normal and strong infill settings and I used normal. My print bed is 200mm in diameter so a square about 150mm on a side will do for a rectangular print bed. I added some polyfil between the baffles and notched the enclosure on the bottom rear, on the side that is open, for the wire. I used 18 guage zip cord. The stuff that comes with the speaker is a bit small in my opinion, and certainly too short. I cut off the connectors and soldered the wire to the tabs. The speakers I used were JBL GT7-4 with a continuous power rating of 20 watts. The amp should be at least 15 watts for good results unless you don't like volume. I like to normally run at half volume to minimize distortion. I think they sound pretty good for a 4" speaker.

Len, I need your help in building an enclosure similar to this one, but with a 6" hole and more waveguide, please shoot me a message and assist me if you have time.
If your printer is large enough you could just scale the box up so the speaker would fit. Most slicers would do it. Cura will. A program like 3D Builder which is free from Microsoft will work. Do not assume because it says six inch speaker that the hole needs to be six inches. I would use a piece of stiff paper and cut a hole in it and see that it fits to find the size. The length of the waveguide could be changed by altering the depth behind the speaker. Just scale that dimension different than the two for the speaker.
