Inverted Sub

so i inverted my 18" fi q today and have the motor sticking out...it is alot louder. i can now do a hairtrick, which is what i have been striving for lol, my question is....why does it make it louder? is there any theory behind it or is it something that just is?

Due to the increased internal enclosure volume and the tuning has changed. That's if it's ported.

huh, how much do u think the tuning frequency changed? the box it tuned to 28 hz, and is 6.3 cubes.

Overall very minimal, tuning wise and iirmc the displacement is 0.24 cubic feet. So your internal cubic feet went up 0.24 cubic feet.

hmm...i wouldnt think that would make that much of a difference, but man it did. i dont have a meter so idk the exact amount but it moved my girlfriends hair quite a bit. n before it never did. screw it, as long as its better i have no more questions lol. does the power handling go down any? like should i turn down my amp or is it fine where its at?
