fi q recone question

[Autruche]

3.5 cubic feet tuned to 30 hz.....dont get me wrong it hits low but with absolutely no authority and its on a t1500-1bd @1.4 ohms but close to 2 ohms after rise

is that box 3.5 cubes after displacement or before? because if it's before displacement it's probably tuned to like 35 hz.

yeah I need some more experience for sure but my friend asked me if he could recone it to a btl and I was clueless so just asked on here

[armyranger3858]

but he and I set our gains with an O-scope used to use multimeter/voltmeter

how much port area per cube does his box have? and make sure the subsonic is turned completely off just watch what you play and make sure its not to low. yes the woofer can take 1500-1750 daily, but only if you know what a stinky VC smells like and you have an excellent electrical system. otherwise don't even attempt it you'll just buy re-cones more than you can even imagine. my recomendation for that woofer would be giving it 14^2 of port area per cube every Fi woofer ive ever used works best like that if you want something that can play everything that is. (my bl can go down to 25-26 hz safely) im tuned to 36 lol
