Hmm.. the magnet on my SP4 has no hole in the middle/bottom, just a flat sticker. Is that the same as your evil sencheezy? Bigjon, thanks but I just re-worked the box for now .

Direct quote from Nick @ Fi - "The cooling is definitely going to make noise, that's just a byproduct of it working properly." So yeah, the subs fine, but I assure you, if you mount this thing inverted you won't like it. So just a warning to others who might consider this - I think the way Fi designs their cooling makes their subs not so good for inverted.

Well I modded the box, ported it out and installed, it sounds normal now, thing slams.. just saying, IMO sp4's are NOT mean't for inversion.

im going to free air it a bit tomorrow to try and determine exactly what is making the noise more, but i dunno, maybe they were cooled differently?

Well, that is true, but I'd imagine something with less xmax, not as crazy of a motor, i dunno there has to be variables. I listened to an inverted jl w6v2 install before and didn't hear any noise like this.

Where the rear seats you to be, its about 2 feet back from the front seats. So its close to the ears and in the main cabin.

Well yeah, I mean I'll prob just try and sell it and find subs that have less noise. Blah just wanted the world to see the giant basket on those sp4;s.

na its coming right out of the motor, i put my ear up to it to find where it was coming from. this is a real downer, i'll prob have to sell the sp4, the whole point of the install was to be invert mounted. Where on The motor? Well I can't say exactly for sure, but it wasn't the sound of coils scraping, it seemed like air noise or something from the coil moving in and out, its probably a normal sound that no one hears when its mounted regularly. Its just really obnoxious inverted and its not going to work for this install. fuck. I'll prob free air it a bit tomorrow to make sure its not box related. What is making you not run it regularly in the box? Its aesthetics, the whole install was for looks. Also the box isn't deep enough now, about an inch shy so I'll have to make a baffle which will also now mess up the carpet.. my god.

Okay, so I guess the way the cooling is designed or the motor or something is causing loud air noise around the motor that is very audiable when the thing is invert mounted. There should be some kinda warning about this, as my whole install is based around the idea of an inverted driver. fml.

They are catching up for one.. If you are not willing to wait for a quality built to order sub then you don't deserve it... buy off the shelf and join the others no reason to say anything about it on here lool its not reasonable to have a 2-3x delivery time than whats estimated. my install has to be done in a certain time period, i can't be 60 days out looking for the sub. just get one used instead. ?? profit. there should be an updated delivery estimation on their website when they are behind that warns of longer delivery times. i have no problem with them busy, i just should be informed as to what i'm getting into.

liked ;p

lol, i just read this thread.. what? i'm order # 1692.. that means I won't see my SP4 prob until beginning of july LOL yeah I'm going to paypal and cancelling it.
