T/S parameters are what you use to size the boxes and select the proper port alignment. Sealed is more tolerant. Building speakers without the ability to measure is usually not a happy experience. This is engineering.

If you described the drivers, maybe someone will have measured them, or at least some generalizations could be made.

H,

You have not even identified which of their speakers you are looking at, nor have you apparently investigated being able to measure the drivers yourself. It's the weekend, get busy.

You also might look at their site again, I just looked up their 12 inch PA bass speaker and it has full parameters listed. ( SP12-200 )
