I would like to thank Dustin B for all your help in getting me started with this project. you guys who help us newbies out are truely awesome. thanks !!!!!!!!!!!!!!!! this is the basic design and this is what i have put together so far. this will be a 3.15^3 box. using the .dvc12 . tuned to 22hz. using 4" pvc with a 90degree elbow to get the port in the front. with the front hole flared with a round-over bit. (thanks for the idea Patrick s.) the corner moldings and top will be natural stained oak knotted pine to match the veneer on the entertainment center. and the middle painted with a crakle type paint. the spikes will be the parts express dayton ones.
