i built this box last week. nothing special about it. only made of birch. it was for testing sub and port orientation in truck. something wierd i found was 36hz tuning is only .1 dB quieter than 45hz tuning. the box has 1 6'' aero facing back. did a 152.2 in the kick. it had about 3000 watts to it and some 16 gauge speaker //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
