i think he was keeping it simple. by pretuned i think he simply meant there are no adjustments to be made to a prefab box.

the doctor gave me some ambien once to help me sleep and i posted on another board and had one of the guys call me the next day to ask if i was ok. i dont remember the post but it was pretty bad. they thought i was drunk and suicidal or something...

that ambien is nasty stuff.. it makes a lot of people confused and doesn't put them to sleep.. my mother is an RN, and has all kinds of problems with patients who get Ambien as a sleeping aid when they're in-patients. They end up totally confused, combative, argumentative,e tc.. then the next day they don't recall any of it.
I'd rather just use some benedryl.. benign and puts ya right out.
Anyway, those prefab boxes are slot-vented, and there's nothing to adjust, but the TS specs really don't play a huge factor in those boxes since the port area is actually based more on quarter-wave length, and that is based on frequency so it doesn't change from driver to driver. That is why you can switch between subs in a ported box and as along as things like the Qts of the drivers are fairly similar, you'll get a usable box for whatever sub you drop into it.. (the ideal volumes can change, but the port tuning.. not so much.)

Alright, now I know about the tuning. And KikiTheCat I agree with you about the benedryl, been taken it for a while and still does the trick. Now how do I calculate the size of the box I need. I downloaded a box-size calculator but I didn't understand the things it wanted me to put in. If it helps I know how much airspace I need and also know the mounting depth and mounting diameter. Do I just add the mounding depth and airspace? Also, airspace is in cu ft. and depth in inches so.....1 cu ft.= how many inches?

all the info you need for that software for box calcs comes with the sub.. the thiele-small specs.
if not, you can get the data from the mfg's website for that model of sub.
that data is pretty important to have for building a box.
