My original plan was to put THIS driver in a ~2 cu.ft. sealed box powered by a 500w Bash amp. I'm sure this would sound quite good, but then I started thinking of ways to up the output a little down low. The problem is, when I model this thing in a bigger box, tuned between 18-20 hz, I get a huge hump in the response around the tuning frequency. When I make it smaller the hump goes away but then the port becomes too long (4" PP) to fit in the box without putting a couple bends in it.
Does anyone have any experience with slot ports and would this even be doable with this driver? I don't really want to do passives unless somebody knows of a fairly inexpensive option that would work out. TCsounds is out of their passives right now. My main goal with this is to keep the size reasonable (under 3 cu.ft.) and have more output and/or sound much better than 12" commercial subs in the $5-700 range. I know a few people that would buy these, so I really want to build something with the least amount of compromises. I guess if that means keeping it sealed for high quality/smaller size, than that is what I will do. I would just like to hear some other opinions from the experts. ;x(
