Fi Technical

Can someone post some pics of the extreme leads? I'm curious to see what they look like lol.it would be greatly appreciated.thanks!

Im purchasing 1 fi btl n2 18 inch, and im not sure whether to choose dual 1 ohm or dual 2 ohm. I have a 4000 watt mono amp with a lowest possible rating of 1 ohm. I used to have 2 12s but im moving to this 1 18 inch and wish to have it running at 1 ohm. Ive read around and from what ive heard, i should go with the dual 2 ohm sub, but i wanted to be sure before this purchase. thanks for your help

Alright im not realy sure about this so ill ask it here. I ordered 2 18in D2 Single stack recones with highxmax coils but there not flatwound. Is my order wrong? im under the assumption that these should be flatwound for better power handling and cooling.

Right now i have a 15 d2 Fi BL its sick... but i cant leave it alone... soooo any opinions on the power handling on 2 Fi BL 15's? and any suggestions on a amp to run both of them on? im thinking about reconing my older Bl but its up in the air for now... so any opinons?

New Fi Q15 owner here. Fresh to these forums too. I just wanted to share about my project and also had a few questions and was hoping for some feedback/opinions. Recently got my hands on BB6 pro and built a pretty bitchin' (and simple) PR setup for my buddy's Saturn ION that piqued my interest to try it again, but bigger and with more power. I used a Resonant Engineering SEx10 paired up with a TC sounds VMP12 (stock 390g mms) in a prefab 1.8cf sealed 15" box. Made a speaker ring adapter for the 12 in the 15" hole, and then cut a hole in the side of the box for the 10". We were very pleased with the amount of LF output this little bad boy has, and still being super clean …

My first major build and I want to do it correctly, please point out potential issues. Just bought an SAZ1500d V.2 amp cause I found a smoking deal and couldn't pass it up. It's on a truck barreling towards my house right now Looking for a sub to pair it with and the Q caught my eye. Looks as if I add the cooling package to the sub I can pump another 200-500 watts into her which will align perfectly with the Sundown's output. Going Dual 2 Ohm coils and wire it all up for total impedance of 1 ohm and I should be styling. Only thing I'm still debating is whether I should go with an 18" or 15" woofer. The 18 attracts me for the sheer fact that it's an 18. It'll b…

ideally, what would be a good power range for the ib3 12 inch sub?

just got my 12 bl hooked up today... its killer on the lows like it hurts your ears but when it hits the highs you can barely hear them. maybe it will get better when it breaks in im not sure... just wondering if this is supposed to happen or not

I ordered a re cone kit for a 15" RE SE 12 spoke basket/motor. I opted for the double spider option, internal leads, etc fully loaded. About how much power can this sub now handle? I did not see any specifications on the re cone page. Thanks for help in advance

Im getting a fi btl n3 18 and haven't been able to find any dimensions to build a box. Can someone please give me dimensions to build a box and I want to tune the box to 32hz and pictures would be great too

I'm in need of the T/S specs for a 15" BTL (2008 Single Slug) They're not on the website. Building a new box for them and I need to have the specs to plug into my software. Thanks

Just what the topic says, i need to know the diameter of a BL 12 magnet.

ok guys i wanna put in my car 2 12" fi q d2 and i dont know how many cubic feet my box needs! i wanna hit lows soo i want it at 32hertz of tuning. i know that one fi q 12" need 2.35 cubic feet after sub displasement for 32hertz i have a 99 maxima and my maximum mesure is 36" width 14.5" height 26" dept i wanna use 3/4 mdf anyway i really need your help and thanks alot! and what type of glue ad nails should i use ... anyway really enjoyed your help

Does this look good?

I ran 2 bl 18's off 2 sundown 1500d's for little over 2 years with no problems at all. Those bl's had cooling, flatwind, daily options. Now they offer to have a 4" coil for extra $50. This time I will be running either an aq or sundown 3500 on 2 18's. With the 3500d should I go ahead and get the 4" coil, Im pretty sure the 3" would be fine since I ran the others with no problems that long. thanks for suggestions

I would like to get a FI 12 Q sub. On the front page of the FI website it says "All subwoofers are custom made to your desired options in 3-7 business days" but contradicts itself when you go to order the sub which says "30 day build time due to US steel delays." Which one is it? I want one of these subs but not sure I want to wait 30 days for a build on it.

I have an ssd 10 under the back seat of my nissan titan and im havin problems with it hitting the grill i have on the box when it pounds. Ive been adding wood to create more space between the sub and the grill but i was wondering if there are any other techniques i could try. Any help would be appreciated.

The website says between .8 and 1.5 cu. ft. for a sealed enclosure. Could someone give me a more exact size? Or at least tell me what would be the difference in sound if it was placed in a .8 cu ft box vs a 1.5 cu ft box? I'm currently running an IDQv3 12 and was given an exact volume size for a sound quality setup. What do you guys suggests? I listen to rock and electronic music. Thanks in advance!

i understand the high QTS option is for sealed setups, but has anyone throwin a Q series with the high QTS in a ported box? how did it sound and would you see a problem with doing this?

Hey guys, I am planning on installing a 10in Fi Q subwoofer in my 2009 BMW 128i. I have wanted to do an install in this car for quite a while but limited trunk space has kept me away until I decided to build a custom fiberglass enclosure. I plan on using an AQ1200 D amp with the Q and with that being said I am concerned with the amount of power I will be drawing from the car to power the amp and sub. Any input would be greatly appreciated as to whether or not this might pose a problem in the long run with my battery or alternator. Thanks in advance.

want to know what fi soft parts to beef up my aa12" havocs .will the motor support an spl optiion or would it be better daily, or in between. .......... FRANKIN HAVOCS ON THE WAY????????!!!P.S. CAN YOU GUYS HELP ME!!!!!!

all my life i have been a sealed guy, i just love the sound of a sealed setup and how low and deep they can play, so i got talked into going ported for my next system..im going with 3 18'' fi Q series, fi suggest 6-10 cu ft per sub, im thinking of going in the middle with 8 per sub, im also going to throw 800 watts at each one, what do you guys think about this? i will be using this for daily driver and i listen to both rap and rock music..so im hoping the subs can keep up with the fast beats..also 28hz sound good to you guys?

I just got my box for my 2 18's Q's but i dont like the way it sounds, it's in my explorer , he tuned it to 30hz in a 13 cubic ft. box, its all high bass. i want a groundshaker. how many hz should i tune it to??

Yo guys I am wondering if any body in north Mississippi or perhaps Memphis has a Fi sub cause I'm about to get myself a 18 btl. I just wanted to see the quality in person and the sound because it's talked about alot in these forums. Thanks again
