well the reason you are comparing the 21" sealed to the 18" ported is because you get more output from a ported. So to make a wild statement, if there was a 26" Maelstrom-X, you'd need to port a 21" to be as loud as the 26" sealed

It doesn't help that I keep on coming up with more options myself. My fiance is pretty open to my building a big box for the theater, it's mostly my own aesthetic that keeps me from building a 20cf ported 21", and my own budget that keeps me from building TWO of them! LOL
oh yeah, I forgot we may be talking "reference" here.... cuz I'm hoping 2 21's in 128cu ft each will be enough...for a whileOnce you get to "loud enough" any more output is irrelevant.
