Enclosure for a 4" car speaker

If you're lucky or have control over your support, the print requires full backing. If it's patterned like the second picture, it will work as a baffle. Adding some Polyfill behind the speaker can also help greatly. It sounds very good to me. I plan to add an eight-inch "woofer" to the .1 channel of a 2.1 amp. The speakers are Kenwood 4-inch car speakers, which come with the mounting rim, a screen cover, and all the hardware needed to attach the speaker to the enclosure for under $23 at Best Buy, but others are available at various prices. I have some coming from Banggood that cost more, but I'll find out if they're as good. I got a small 2.1 amp, powered by a wall wart, but I use some 12-volt batteries to minimize power supply noise. I also have a little tube preamp that adds warmth and only costs around $34. Most phones can decode and play FLAC-encoded audio, which is lossless. If you have a phoneograph, it will sound the same or at least as good as a CD. MP3 made me tired of music, but I've found it again. The foam is to fill any gap between the speakers and the enclosure. It looks like if you use the Kenwood, you need a strip of thin foam doubled and lining the hole before putting in the speaker. You could also print the box at 97% and tighten up the hole a bit. I imagine there's probably a range of hole sizes needed for various "4-inch" speakers. It takes a while to print - my current printer has been working on it for 47 hours. I added a 97% version, which fits the four-inch speaker better.
