Hopefully it's cool for me to post here to ask a few specific questions about your subs? I am looking to build a ported wedge box for a DCON. I have plenty of room for a 10 but a 12 would be tight (i would prefer the 12 of course). 1st question is how much room does the sub need to have behind the magnet? If it's less than 1" is that too little? 2nd question is what diameter port should I use? I need to use a round port to save some air space in the box, for a 12 should it be a 3" dia or 4"? I can barely squeeze 1.75 cu after port and sub.
