Thanks, will do

That could work, I have about 8ft of height to play with, that will give me about 10 cubes. In that case i can just tune the port to 18hz like you recommended.

The problem is that I don't have the space to go that big. I like the Sonosub idea but the problem is that where I'm from (The Netherlands) Sonotubes are really hard to come by. So I'm stuck with either a 95 liters sealed box or a small ported box with 115-120 liters.

Sorry, forgot to mention the sub will be used as a home theater sub in a 14 x 24 ft room.

Hello everyone, 2 Weeks ago i received my eagerly awaited mj18m sub from mach5. Now I've been thinking about the box design for quite some time now and had initially decided to go with a sealed box because I don't want the sub to take up a lot of space. But after modeling the results with winisd I noticed that with a fairly small (115 liters) ported box tuned to 28 hz I get a much higher output obviously, but also a pretty good frequency curve. So now I'm contemplating if I should go with a small ported box instead of going sealed. But since the recommended ported enclosure for the mj18m is 142 liters I wonder if going that small is smart. I want the sub to sound as good as possible thus my main concern being that I will lose some sq if going ported. So some input in this matter would be greatly appreciated.
