Fi Technical

What would be good for getting the most volume out of my 10" Fi Q. I want it to go ported for some more output, and it'll be running off of a MD1D at 1 ohm (1200 rms). Thanks a bunch

since some of you knows very well this product i though it might be a good thing to ask before making a choice... i got a btl 12 that will run on a soundstream tarantula trx2000d... ive done the big 3 and im wondering how to maintain a constant 14.4 load to my amp?? plus a need a box desing. im gonna be using this sub daily for mostly hip hop and got a mazda protege 1999 with enough space in the trunk . i also heard that a square box aint the best option since the sound produced by the woofer would hit the back panel then bounce back troughout the cone area and produce distortion(by the way sorry for my english im french) is it true???? and thats about it thanks for you…

Hey guys, my enclosure is nearly finished. The specs are.... It's 3.97 cubes before displacement, so I am guessing around 3.5 after due to the sub displacement and the bracing. The box is tuned around 33hz. I've tryed it in my friends vehicle and it pounds pretty hard. Not 100% happy yet. I'm thinking that's just because it's not broken in yet. I heard it in a Ford Expedtion, but the sub will be going in a 96 Cutlass Supreme. Hopefully it will get much louder. I'm powering it with a JL 1000/1. But what I'm wanting to know is are those good specs for the box? That's about the biggest box I could fit in the trunk. Help would be appreciated!

:bigclap: hi I am new here and I wanto to know How I cant buy a FI speaker. I need to aknow a telephone number thanks my email is [email protected]

The ssd 15" does 21 mm xmax. How did you guys get 27 out of the Q15" with only 200 more rms? Also will it be alot louder then the ssd 15"? Its going in a ported enclosure.

will the 3500d be enough for 2 btl?

I am going to build (or have built) a 1.88 cu.ft. enclosure tuned to 32hz for a 12" Fi BL. I want to put a round port in the box or multiple round ports or even a triangle port. Can anyone tell me the dimensions of the port? I know there are tons of calculators out there but i don't know how to take in account port noise and all that fun stuff. I don't know whether to put one port or multiple or anything. Thanks in advance!

Hi i was wondering if you guys could make a recone for these subs. #1 AudioQue HDC3 15 #2 DC SOUNDS Level 4 15 Both dual 2's What soft parts will be used and how much? You can post here, PM or email me [email protected] thanks in advance.

I had the Q in my car hooked on a bxi2006d @ 1 ohm. Never really pushing it tough. Never ever smell the coil either. Now i change my car setup and decide that this sub would fit nicely in my home audio setup. so the big sealed 7ft/cu net box is now in my room. It is hooked up on a getho amplifier setup with a 22amp rail psu and a ma 1889i amp @ 1ohm. getting around 240watt max with the psu capacity well, the other day i realize a kind of rattling like noise with the sub playing at extremly low volume. At first i tough it was something on the wall rattling but then i realize by putting my ear next to the cone that the sound was coming of the sub. I've been using the same e…

Never mounted an amplifier right next to a woofer before, so it i tried it. Currently I have two 15" Fi Q's mounted invertedly behind the back seat of my car. There was just enough room to mount the p450.4 in between the magnets of the Q's, which positioned the amp perfectly at the reach through in the back seat. Doesn't seem to affect any perfomance aspect of the amplifier, so I guess all is good there, maybe i got lucky, or maybe i'm just sketchin. Next item of business though, What about mounting batteries too close to woofers? Does it matter? Talking kinetiks here too, not some cheap lead acid. I wouldn't see why this would be a problem, but I learn new things al…

Ok, so I finally finished stage 1 of my install today. It's gonna take too much time for the custom fab needed for my components to fit in my door so I used a Line Out Converter to get me by. I couldn't change out my HU because of the factory amp and it would cause the speakers not to play and there is no harness for it yet. Anyway, back to the point of the post. So I have my Q in a sealed box with about .8-.9 cubes after displacement. It's a cheap $20 prefab box. I'm just not happy with the current output of the sub. I've seen 10" Q videos, sealed and ported, where there was trunk flex and the rear view mirror noticeably vibrates, and this is only on 1000 watts. I'm runn…

Will tuning to 35hz be good for daily driving? Alot of people say that tuning is a little to high for a btl. What do you think?

Can it be sealed and sound just as good ported?

Has the title states, how do I get a 1 ohm load with 2 btls? My first previous subs where dual4 so I wired them in parallel. Do I need dual1 ohm? If so how do I wire them? Thanks.

I have just purchased 2 15" BTL Fully loaded. They are on 2 mmats 2100.1. I just got them and they SLAM!!!!! I am seriously and deleriously happy BUT I know I could be happier. My box is very small for these subs and I drive a big car (Crown Vic) so I know a new box is a good idea. My current box dimensions are 48" Width 17" Height 17" Depth, measured OD......Port is 4.5" wide divided with .5" 15" deep 15" height, measured ID. This car is CLEAN CLEAN so with that in mind I don't want to go tearing it apart...totally. I dont mind ripping out the metal behind the seat or cutting the rear deck. Here is my goal: I want this system to BANG and does already but my trunk sounds…

Well , finally got them in for recone. I had the pair ported on 1000w total and it was pretty good. I am going sealed now with 1000w on each woofer. (Zapco Studio 500 on each 4 ohm mono) So I see Nick really like the 1.1 sealed and other like the sealed in the 1 cu. Ft. range. My concern is for such a small box is that its not playing deep enough. I was leaning toward a slight larger, maybe 1.3 cu ft or so after displacement I would like to hear anything anyone has to say. Beat me up a little.

I just ordered my dual 2-ohm Fi Q15 last night and will be ordering the Cadence iA7 today. I was hoping that one of you would be able to point me in a good direction as to where I should buy an enclosure for this, or where I could have one built. I plan on going sealed, is there an ideal size besides just 2-2.6 cubes? Any other suggestions? Thanks guys

I'm trying to figure out the port diameter and length for a box I'm going to build, but every time I use a formula from the internet I get something that doesn't seem reasonable. The box is for a Fi SSD 15. I figured the dimensions are 25x15.5x17 which is 3.81 ft cubed. I'd like the port tuned to 33hz. If anyone could help me out it would be greatly appreciated. And if you could leave the formula for future reference that would also be appreciated....thanks

Hey, just received my 15" Fi BL and just constructed a box for it. Box specs: Port Area - 55 Volume before displacement - 3.97 Frequency - 32.2hz - 32.6hz Setup: 15" Fi BL Jl 1000/1 2 awg wiring Stock deck Stock Electrical Here's the problem. My freind with a 12w7 in an H/O box kicks this subs ass! His Setup: 12w7 in H/O box Alpine PDX 1000.1 4 awg wiring Alpine deck Stock electrical His system is in a Dodge Magnum mine is a Ford Expedition soon to be a 96 Cutlass. My plans: Kinetik HC 1800 or more Non stock deck Big 3 under hood Maybe new ALt What else do I need to make it pound harder? New amp? Is the box good specs? Help would be amazing!!!!!!

alright im dead set on the 12" SSD and then i heard this for a review... "i hated my ssd's my two 10 d6's will beat the piss out of them all day long(the ssd's were 12's). I've had a D6 12 as well and it sounded better than the ssd's. I will never buy and FI product again. One of my woofers was DOA when I get it. Then I had to pay to send it back then pay for the repairs and to ship it back. Then the woofer worked for like 2 weeks and the same problem happened AGAIN! So I threw them away. I was never impressed by the subs they were just mediocre. They sounded alright but there was some notes they didn't get and they didn't dig very low at all. I had about 750 going to ea…

I saw NDMStang65s post and how he hit pretty good numbers with a single 18" BTL and a hifonics bxi2008d. I'm getting a set-up like this and I was hoping ( talking mostly to NDMStang65) If you could hook me up with a good box design to let the BTL get loud Thanks! Cody

Ok so i have a FI BL 15 Fully loaded powered by a Sundown SAZ-1500d. Ok so anyway when i play some music loud i hear some weird sound like the sub it bottoming out but i know its not becuase its not moving enough to bottom out.

I have 1 15 BTL Fully loaded, i was playing it today and it started smoking then went out. I have it on a Orion Hcca 5000, the gain was not up it was below half way, i wasn't playing it for a long time, i don't know what could be the problem. I have heard that Orion amps are hard to tune, i dont kno what the HPF ,and the LPF is suppose to be set to could someone help me.

Ok so how do i wire my speaker wires from my box terminal to my amp just - - and ++ this is for 1 ohm

I have a 12'' Q with Bp and its powered by a hifonics 1208d. I was wondering if the amount of cubes made it sound different. I know it does but how much. I wanted to go with a 2.5^3 tuned to 32 hz. The only problem with this is idk if i will have the space. So would 2 cubes sound any different and how?
