[IMOVeCHICKENS! 10+ year member]

i wanna know numbers this is deff something different then you usually see on CA.com

 

[Kryptonitewhite 10+ year member]

Im not expecting any decent numbers for being 4 18's walled off... they're still only IB3's and it's 50 cubes, 23Hz tune... it SOUNDS amazing though! What would be a good number for a low tuned, flat responce setup like this with so much airspace?

Glad you guys like it! I'll keep the vids comin then! Maybe even copy/paste my build log over here?

Doesn't look very loud, just looks like it moves a lot of air.
