We're now offering colored 3D printed rings for those who want to put an extra special finishing touch on their install. They come in all the primary and secondary colors, as well as black and white! You can buy them separately or choose a color to go with your PinWoofer system. Just be aware that if you buy them separately and are using them with speakers other than our Pyle brand (which we designed the rings to work with), you're responsible for making sure they fit the pre-populated hardware. We can't say that they'll work with every other speaker brand. Most 4" and 5.25" speakers have similar hole patterns so it's not hard to determine with a little research. Our rings are pre-populated for you with stainless steel screws and a nut and washer pack specific to the platform.
