Fi Technical

everyone has proclaimed the Fi as the sub to own im wondering if there are any build pics that you can release to the public i.e. ( showing the differance between Q/Bl/Btl/Btl^ loadded ) motors, spiders, coils, and how the back plates are put together etc etc etc i like the way they look just curious

What is the lowest amount of watts to feed a 12" Fi Q and still get decent/good performance? I'm shopping for an amp and want to see what my options are.

I recently purchased one SSD in my old box and i absolutely love it. I will be ordering a second sub in a month and need to build a box for it. I am trying to figure out the dimensions for 2 12's around 4 cubes tuned to 32 hz. I am not sure how to create a box that fits these specs. My dad and i built a box for a w6 but all the dimensions were given so it was very simple. Any past build specs would be very appreciated.

Well right now im running one 15 Fi Q in the trunk of my civic. The box is around 3.2 after displacement and tunned around 33. I got it ran off a memphis 1000D. It sounds pretty good but i was thinking about doubling my power and getting another 15 Q. Problem is i barely have enough room for one in my trunk. My civic is not my daily driver and i was possibly thinking about walling it and running 2 15Q's off of 2000rms. I was just wondering everyones opinions on this? Would it be worth walling with that power and how do u think it would sound in a good built box. Any help or sugestions would be appreciated, figured i would get some opinions before deciding on this, thanks

Could somebody help me to design an enclosure for the Fi BL 18 inch. I'm not good with the programs. I would like to let the box tuned to around 32 - 30 hertz. I'm gonna power it with around 1800W RMS. If somebody tell me the volume of the box and the port lenght and also the port area.

whats the most power you could safely put through a btl 18 loaded, and not blow the coil? im just wondering what some have tried and found to work where as someone might have tried ____ and blown said sub.

Hey everyone ! I got the aq1200d and the 15" BL ready but i made a ported box that i want to make smaller for more room in the trunk and its just a pain to get in. I was just wondering what is the smallest ported box measurements I could use to get as much as i can out of the sub while being tuned to around 32-33 hz. Please help! thnx

Scott suggested that I do a 0.47 cu ft box. I'm having trouble finding the right dimensions. Can anyone help?

I need box plans for a Fi Q12 (dual 2). It going to be powered by a Sundown 1000D. I want it to get loud but also have SQ. So Im thinking tuning it to 32hz. Fi recommends 12-16 square inches of vent area per cubic foot of volume. The demensions I want to use are 14.5 H, 28 W, 18 D. (can change alittle)

Recently Purchases a 10" SSD Fully loaded, Dual 2 Ohms, Standard QTS. The amp is a Kicker ZX1500:1 at 4 Ohms. Just curious as to if anyone here has ran an SSD in a T Line and if so what advice do you have as far as box size etc etc. ,Ethan

I have an Older 12" Q thats blown. I''ve finally decided to get it reconed but I want to build a ported box for it too. I see the the diagrams and cut sheets for the new Q, but i'm not sure if that will work for older model Q. It's also unfortunate that the cut sheets for that one are a tad too large for my trunk. I have a maximum of 30W 15H 18D, but depth can vary a bit. i was hoping on building the box during the time it takes to get my Q reconed. That should give me enough time to learn how to design a ported box. I have no idea on how to calculate port length and all that jazz. Thanks.

I was wondering to expand my knowledge and thought others here would benefit from my ever growing thirst for knowledge... i thought i would ask to help myself avoid these problems and also help educate those that aren't aware of these issues and how to avoid and/or discover the following problems.. Anyways.... as it pertains to sub woofers (particularly Fi built ones since i own some) 1. What is mechanical failure? 2. What are signs of mechanical failure (sight, sound, smell)? 3. What are the most common reasons for a sub to experience mechanical failure ? 4. What is thermal issues/problems in regards to sub woofers 5. What are signs of Thermal problems/issues (sight, so…

would anyone on here be able to help me design a badpass enclosure for 4 18" BL's. The max dimensions are 21H x 49W x 72D and i wanted to tune it to around 29-30 hz. if someone can help please let me know asap.

Ok this is a repost from yesterday, but I never received any responses. So i am reposting in the technical section. I currently have a Memphis 1000D left over from a previous setup (4 - memphis PR 12"s) in a blazer. I have since sold that vehicle, but still have the amp and speakers laying around. After learning about Fi Audio and reading more and more about them over the past week. I am interested in purchasing one 12" Q to go under the rear seat of my 05 Ext Cab GMC Sierra. I want to use the existing amp to power the sub. If my memory serves me correct, it is capable of 1100x1 RMS Power @ 1 Ohm Mono (14.4V). I'm wondering if I should add the BP option to the sub to allo…

ok so what im gunna do is put a single 12" BL into my f150....i have a bench seat in the rear so im gunna fold the short side, which is behind the passenger, and put the sub box there....i have approximately, 18" wide 16" deep and about 20" in height...the height is flexible tho....i have a kicker zx1500.1....can any one please help me design a box? thank you

How do these plans look for a BL 12"? Flickr Photo Download: Screenshot-01 Jan. 02 Thanks for your help.

i have a box i was using for some other woofers in that i put to use in my trunk. here are the measurements 35x16x16 with divider and two four inch ports 8" long each i kinda wanna stay with this box for now because it fits perfectly. the problem is tuning what is this box tuned to and what should i change with the ports? the wood is 3/4 mdf. any suggestions? thanks oh yeah in case you didnt know 2 fi ssd12's copper option in the box.

I have 2 mtx thunder 7801d amps and was wondering if that is enough power for 1 of the Bl 18's? If yes what options should I choose for the Sub? I know I'm going to need the daily option for sure, but after that I'm lost.

i have a FI bl 15,cooling,daily, universal d1, im (thinking of) adding another bl to my car (not like i really need it ) but is there i could wire 2 d1's down to 1 ohm?( wouldnt it end up at 1/4 of an ohm? or 4 ohms) i don't think you can but, hey theres always hope(or none) but i was thinking about getting an excessive amperage alt like a 250 amp, run 0g wire front to back add a kinetik battery all KnuKonceptz wire, with maybe a crunch or hifonics amp Ideas or comments?

im looking to get help designing a new box for my 18" ssd. the box is going in the back of my 00 expedition with the 3rd row seat gone so space isnt a problem. the amp is a rockford t1001bd. specs for the sub say 6-10 cubes 32hz. should i do the 10 cubes? or smaller? and am i better off running the 1 sub at the full power of the amp ( birth sheet says 1400 rms at 1 ohm) or running 2 18s and dividing the power? also if i did go with 2 subs what kinda cubes should the box be?

I will be building my first custom box for a Fi Q15. I will be putting it in a 1994 Toyota Camry. The cargo space is 14.9 cuft, I will edit my post later knowing the actual dimensions I know there are a lot of experts on this forum that can give me some helpful advice on how to prepare the box and how to correctly brace it. I have used a layout generator online and I was wondering if these dimensions were suitable for it. Net Volume: 3.3 cubic feet Tuning Frequency: 32 Hz Port Width: 4.75 inches Port Area: 78.375 Square Inches Port Length: 55.25 inches External Dimensions: 28 wide x 18 tall x 26.75 deep. Color Count Width Height Top/Bottom 2 28 inches 26.75 inches Red 1 2…

HI. How many costs RECON to BTL + shipment? How long are they waiting for RECON? How to order RECONKIT quickly from the FIcaraudio company? I sent 3 messages Email to the [email protected] address and silence. Nobody is answering please help my BTLs 18" ; Ohm: dual 2 P_Chamfer: no Cooling: yes HiXmCoil: yes Daily_or_SPL: Daily Induct_Heat_Ring: yes Universal: yes

My space is 39" wide and I can go 20" tall. How deep do I need to make the box (and how long AND wide does my slot port need to be) to have a net volume of 4-4.5cuft and a daily tuning of 30-33hz? Power will come from 2 sundown saz1500's strapped at 2ohm. Thanks

Can someone answer this question for me; I see that they offer a lot of upgrades, but each one will affect the parameters and driver's behavior. It would be nice if they offered updated parameters and more information on each of these upgrades. Adding mass to the assembly, then adding spiders and changing spider packs, changing coil assemblies, and materials etc, does quite a bit to affect the driver's behavior, from altering moving mass and resonant frequency, causing QES changes, and inductance variances to causing shifts in the CMS curves... All these things really affect the driver's behavior as a whole, the way it will sound, and they even affect the enclosure design…

is the mt dvc 1.4 copper coil available through u guys here at Fi?
