The designs differ mainly in acoustic approach. Back-loaded horn and transmission-line shapes are large, multi-part prints that aim at a specific bass response, while compact cases and stands are smaller shells built around an existing portable speaker or a single full-range driver. Subwoofer enclosures sit in between: they are usually bigger than a desktop case and often use thicker walls and internal bracing.

Before printing, read what the author lists on the model page: driver diameter and cutout size, internal volume, wall thickness, number of parts and how they join, and whether supports are needed for overhangs or internal channels. Check the material and settings the author mentions, since large enclosures are often printed in PETG or PLA with several perimeters to keep the walls stiff, and look at photos of real prints to judge surface finish and fit.

If the results are too narrow, try related terms. Searching for speaker enclosure, horn, subwoofer box, driver mount, amplifier case or decoder board housing brings up different families of models, and adding a driver size such as 3 inch or 4 inch narrows the list further. You can also search by the part you need — baffle, port, grille, stand or battery holder — instead of the whole speaker.
