ok first does anyone know the resonant freq of a 96 ford explorer sport, i did a search and some one said for a 97 its like 37-38, so is this right and would it apply to mine, also i have a crx style box with 4 12's common chamber my ? is i have a 2x4 bracing the box right in the middle top to bottom some one told me that a 2x4 would kill my spl score is this true? last i have four 4inch round ports 12 long how do i figure those into my box to get the exact cubic ft right now with subs its 5.7 cubes. thanks! fine tuning is a b***h!!!!!!!!!!!!!!!!

37 hertz seems kinda low. Just get some test tones and play each one. The loudest one would be your resonant frequency. There is a member on here by the name of kan3 who has a link to a page where you can download free test tones. Give it a try. Remember no one can tell you what is best for your vehicle and what will sound best but you.

I have a 95 explorer XLT and the tuning frequency for me is about 45-46 Hz. i dont think that a shorter explorer sport would be a lower frequency. id say try somewhere around 53-56Hz that would be about my guess. Are you going to tune a box port to peak at this frequency? i did it in my xplorer and i gained about 1.5 dB but it wont play low notes and sounds kinda sloppy. good for competitions though. just a warning.

right now my box is tuned around 40 hrz, i got the test tones dl and played it and 50-53 sound the loudest to my ear and hurts the most to so i'm guesiing thats what my peak is after 53 it sounds like its not hitting as hard
