Speaker enclosure for 4" Speaker

This prints as one complete piece, and if your supports resemble mine (image), I recommend leaving them in for a better overall appearance. The enclosure requires full support to print correctly. It measures approximately 150 mm square and 160 mm high. To enhance the box's dimensions, I added polyfil behind the speaker, but not directly against it. This setup helps make the enclosure seem larger. I'm pleased with the sound quality, which is impressive considering the low cost of the speakers. A Kenwood pair from Best Buy costing under $25 works well; any 4-inch speaker should suffice. To prevent air from escaping around the speaker opening, I used thin foam. So far, I've printed six units. For amplification, I'm using a budget-friendly 15-watt per channel amp but plan to upgrade to 20 watts for added headroom. These speakers operate on a power range of 12 volts to 24 volts and are primarily designed for automotive use. I was impressed by the clarity of FLAC-encoded (lossless) media. Most modern smartphones can decode it using the VLC media player app, making playback effortless. Some compact amps even support Bluetooth connectivity, further simplifying the process.
