I was just wondering if this box would suffice. Opinions?Sasquatch...

We know your legend's real...

that should sound pretty good...I always like type R's in ported enclosures between 2.5 - 3 cu ft

Alright thanks man... Should I really expect around 110 db's out of that one 12"?Sasquatch...

Likely to be more than that due to cabin gain (if you set the system up to achieve such a goal, that is...).Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Is setting your cabin gain when you get an o-scope and the whole nine yards to get super SQ? If it has to do with that I wasn't really going for that. I was just trying to design a box to make the woofer be really dynamic.Sasquatch...

Oh okay. Well I was going for more of a sound quality box but would like it to be loud. From the look of those charts do you think it'll sound good?Sasquatch...
