FS of a Sub, and box Tuning>>>

Hey dman, you want to design me a box?

this is a plot of my enclosure, and there is no audible response change over the range. So where is the drop in upper frequencies?

they tune high because it induces a peak above the rest of the range such as this curve (different driver, but the curves work the same for all drivers I have ever plotted)

Huh, well I guess you're probably right, but for some reason every box output calc i've ever used has shown a slight decrease in upper response and a more linear bottom end from tuning lower, using the same driver specs.

let me know what you would like from the enclosure, and pm me some theile for whatever driver

You're literally tuned just under your FS spec as the pic shows, you will absolutely not have the same output all the way up to 80hz with a 24hz tune, that's not how ported boxes work. You probably have a significant roll off around 50-60hz, it's simple math and common sense you won't ever get same output on that wide of a range.

Welcome to the site, but this thread died back in 2008.
