[QUOTE="i2ain2thunder, post: 7493750, member: 631331"] Hey guys hope someone can help me. (on this subject my knowledge level is that of a retard so take is slow/easy on me plz) Anywho looking to find a good xover point for my LPF for my subs. I hear that I might like having a 6db rolloff quarter of an octave above my Fs...so the equation would go ((((Fs*2)+Fs)/2)+Fs)/2 I'm not sure what factor to use for Fs do I just use the specs for the woofer, because mine say their Fs is 21hz. Which would land me at a LPF setting of 26.25 and that doesn't seem remotely close to being a good xover point. Is there some other Fs spec, or does the Fs change based on the enclosure? Or do I simply have no clue what I'm talking about here lol.[IMG]//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif[/IMG] [/QUOTE]
