Peerless 3 inch full range project

this is my full range project using Peerless 3 inch full range woofers. The box is very small for what the speakers called for, but i was trying to stay this small. The box is 16 x 5. 75 x 5. 75, with 2 1x4 inch ports. And is great to use with a mini amp and a mp3 player. that s exactly what i did. I got the speakers and ports at parts express.
