I get everyone throwing options at me, but I can't tell which one is really the best...because no two suggestions seem to be alike. 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

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

That is the way Internet forums work. If you want a plethora of opinions, none of them the same, just ask in an Internet forum. :laugh:

If it were me, I'd just build a big sealed 21". Ignore the people saying you could get more output. The sealed 21" has PLENTY of output and it goes smooth and deep. I love sealed subs but you need a lot of swept volume for them to work well for HT. The smaller drivers NEED to be ported, to give the extra headroom. The 21" has an abundance of output, without the need of porting. It goes subsonic with ease because you don't have the roll-off under the port tuning. It sounds awesome.....

Can a large sonotube be sealed and be just as effective as a braced box?

, glad you talked the bloke into doing the 21", thats going to be awesome.

By 'smaller' do you mean anything smaller than the 21"? :gulp:

Sorry... missed this. No... the 18" is a beast too. It is just that the sealed 21" has enough output that most people are not going to be wishing for more. I'm sure there are a couple crazies that will prove me wrong but a single sealed M-21" is pretty tasty.

Once you get to "loud enough" any more output is irrelevant.

Sure... Sonotube is great. There should be no sound quality difference between a properly assembled and braced rectangular cabinet, and a properly assembled Sonotube.

You can pick which you like purely based upon personal taste.

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 while
