Re: meet X3-122
yea, after I get these fuckers to fit in my box. I was going to build a new box but it is too much bs and not enough elbow room to squeze anything bigger in there anyways. So I have to add poly fill and my calculations say that this 3.75 cubed box will increase to about 4.5 - 5cubes. and the tunning will hit around 38hz. which is fine.

If anyone wants to design one free of charge please do so...
I dont have space to expand. That is why I am resorting to polyfill. I can take my 3.5 cube box tunned to 33 and add 3 lbs of fill and that should give me a gain of about 1.5 cubes, according to my research. It will raise the tunningto probably 38hz?
