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.
These are recomended
Hi Tunned
MIN -2 cubes - 2 ports at 4"x14" - FB 50.1 - F3 38.0
OPT -3 cubes - 3 ports at 4"x12.25" - FB 50.2 - F3 37.8
MAX - 4 cubes - 3 ports at 4"x6.75" - FB 50.2 - F3 37.8
Low Tunned
MIN -2.5 cubes - 3 ports at 3"x14.75" - FB 39.9 - F3 31.
OPT -3.5 cubes - 3 ports at 3"x12.50" - FB 34.8 - F3 28.2
MAX - 4.5 cubes - 2 ports at 4"x15.5" - FB 29.9 - F3 25.0
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?
