This is a basic custom ported enclosure. It will be the vented SQ enclosure shown in the picture i have attached. Built for the 12" Subwoofer at 1.9 cubic feet tuned to 36hz.

The enclosure is my basic line up. I have countersunk the side panel for my terminal plates so it will come with the terminal plates prewired with 12g OFC speaker wire. It is made of 3/4" MDF. 

Standard cutout for the subwoofer is 11.125", if you need a different cutout diameter then please specifiy when ordering and I can make you a new and custom one. If you do not know your cutout diameter then please feel free to just give me your model number of the speaker and I can look that information up. 

It will be built to the dimensions shown at this website (the port exits out the front, subbox pro has limitations but i like to use it as a visual representation).
