    sealed slash ported 18xxx box

    anyone else with bb6p wanna conferm this with me. I'm going sealed with the 18 for daily with a removable port for comps. an I want it to be ultra sq daily. and ultra high ported for comps. and so far the **** thing is telling my that to get a gtc sealed anywhere near .707 i'm going to need a 30 cube box. which works out cause if I make a removable panel the ported box ends up being 30 cubes with a 28x30 inch port/hole in it that if as deep ad the baffle (1.5) will be tuned to 48ish.

    well if you want ultra sq you want to try sealed. but i dunno i love the sound of them but for that big and powerful of sub i have no idea how it would react

    thats what I keep thinking. thats why I want someone else to run the 18xxx through bb6p also. cause in a 4 cube box the qtc ends up being 1.392 whic I do not want as the frequency response looks like a ported box would. i'm also wiring each VC to its own 900w rms amp for anyone who's doing the numbers

    Re: sealed slash ported 18xxx box

    Vb = Vas/((Qtc/Qts)^2-1)

    Vb = 244.2/((.707/.59)^2-1)

    Vb = 560.2L = 19.78ft^3

    So, for a Qtc of .707 you'd need an enclosure volume of almost 20ft^3 according to the 18" XXX's specs. Reason the enclosure has to be so large is because of the relatively large Vas and high Qts

    lol I might have to build a wall for a sealed sub. squeak help me out bro. you know I'm wiring up each VC seperatly to it own amp which throws things off. if I wired them in parralell down to 1 ohm in a heavy stuffed 4 cube box I would get .707, but my amps are only 2 ohm stable
