I plan on ordering an SDC2.5 12 incher from AQ when they get them back in stock. I started this build with the thought that I would order the sub this friday but went on the site today to find they are unavailable and it could be months until they are back. I fried my previous sub so I have nothing to put in this box. This is my first box build, the others were just pre-fab. I did not use MDF, I asked for it but the lumber yard gave me what I presume to be MDO.
The specs are 28L x 18D x 20W and the port is tuned to 38 hz.
