Default how big do you want the box?

cause that usually is a limit...

ok, the Delta isn't really a subwoofer. do you already own it? If not please look for a true sub, with a lower fs, and a smaller Vas

I was thinking to some data abou sub constructing....nothing special, just because I have speaker to put it in something :-)

Also I have one dynacord 12'', but don't have data except 8Ohm 250W.
