Well, it took about a 2 weeks to complete it, I was pretty busy but it only took about 15 hours total to finish it. I neglected to put bracing in the box, even though I had cut 2 pieces of MDF to go inside it, but my best friend said I wouldn't need it I put a bunch of 1x2's in there anyway and that seems to have worked. My initial impressions were pretty good as I was not expecting this much bass from a 12" sub!!! MY GOD! I put a cd in that I made with 10 second MP3's of HZ ranging from 10hz to 99hz. I tried the 20hz clip but couldn't hear a thing, but a few seconds into the clip I heard something fall upstairs, turns out it knocked one of my mom's clay masks from mexico off the shelf, hahaha. I wasn't too sure if music would be good with this sub but I was WRONG, I played all kinds of music ranging from R&B, rap, heavy metal, oldies etc etc and I was VERY impressed with how it sounded, not boomy at all, extremely tight and LOUD! I havn't had a chance to watch a full DVD movie yet, but I did watch the pod race scene in TPM and had the same earth shaking bass I was getting with the music. Man I love this thing!!! I didn't put any Polyfill or foam liner in the box, as I didn't have any on hand, but would this make much of a difference. I also have to finish up the laminate edges a bit, as some of the contact cement is still there, easy to rub off, just need to find the time. Here are some pics of it, comments welcome. http://communities.msn.ca/Camshumbleabode/shoebox.msnw PS. Thanks for all your help guys I couldn't have done it without you all, especially Kyle Richardson!!!!
