  1. Hey Ray I know your real good with 4th orders and I was wondering if you could point me in the right direction as far as my 4th order... I have 2 12's im playing with until I decide if I like the 4th order then ill be using 4 12's. I have 4 Fi Q's(old double stack) and I wanna be able to put up numbers on the low end like 25hz and not be worried about it. But want it be able to go up to 60hz too. Im trying to figure out the port area and sealed side problem my box now throws serious air from the port. It 14.5sq icy per cube a 2:1 ratio( without polyfill) and I have. 8 cubes per sub sealed and a 12oz of poly per cube. Any thoughts?

  2. Ok guys im taking out the 4 12's and building a small 4th order for two of them to :

    1. See if I like the sound and

    2. See if I get any louder and lower

    I was a 144 at 36hz I believe with just two in a small temp blowthrough box. Im at a 148.2 @ 32hz right now with a dead front battery the lower I went the higher the score went but my run ended and I wasn't aloud to find my peak before hand :/ well you now know the idea and plans this will be 2asking Fi Q's on a Crescendo Audio BC5500 at 2ohms.
