General Fi

Was thinking, and wondering if Fi has contemplated making some ear buds? I know myself, and many others i'm sure would be all over them. I have no doubt they would sell like hotcakes. I would love to see some high quality buds in the future. With awesome drivers, and a better cord then {others} with maybe a "Fi" logo built in anyways, those are my thoughts.

I have a 12" bl and today I am pretty sure I blew the voice coils on it. I was driving around and the sub cutout and I opened the back of my jeep to see that there was smoke coming out of the port. I know for sure that I had everything wired right and i didn't even have the gain up that high( a little over half). I am going to re-cone it but I was wondering if anyone knows what could have caused this so I don't blow the new I get. Thanks

hey guys i have a new RF t1000bdcp amp that i have hooked up to my fi bl. i have the dual 1 and have it wired to 2 ohms. i have my gain about 3/4 the way on amp because my h/u preout volts are 2.2v. After i play my music for about 20-30 minutes at about 3/4 volume my amp will get extremely hot iv had people burn there arms on it when they set it on it cuz its on my sackseat and its folded down. I was wondering why my amp is getting so hot its crazy. is it because i need a new h/u with 4v preouts or could it be something else and what? i have no bass boost or anything on on amp or h/u.

Hello everyone, Ok so im thinking about adding a second battery in my car in the trunk to maintain voltage drop. right now iv got a red top under the hood, about to do the big 3 and a 120a stock alt with a rockford t10000bdcp and a alpine pdx f4. Im planning on getting a kenetik hc800 in the back to add a little more power to my electrical. What i was wanting to know is would this work properly and just add power to my electrical or will it burn out my alt or anything?? i know iv heard of people adding a battery with a stock alt and was thinking it would be fine because i really dont want to spend 600 on a ho alt right now. my local stereo shop says i need a bigger alt an…

I have a BL 15, but im thinking of bumping up to 2 BL 15, but what is a good amp that can power 2 fully loaded BL's? and what kind of batterys? im thinking of facing the subs up. or straight back, or face both inside of the ride and close it up... im just wondering what amp... i have a redtop, and have the big three... jus little things, but im wanting to upgrade.

Hello, So there has seem to be some confusion lately about the N series, and I wanted to start a topic to clear things up for the normal users who may or may not know what to buy. So could anybody that either works at F.i, or anybody that has and tested any of their N series equipment, please explain their use and purpose clearly. For example, what is the difference between the BTL N1, and the BL for instance. Why so many different lines and different job specific equipment that may confuse the consumer or may be overwhelmed by so many options? As of right now, the website has 6 total different lineups, and if you include the BTL series, you have a …

ok i just got my fi btl n3 today been waiting a month for them they look like something from outer space i was inspecting them and i see some metal shavings around the magnets dont look 100 percent centered and the glue that was applied some parts are black then turn white is this normal quality control?

Is there any time frame on these to be available? As in a month. Two months. Longer? Just been looking around and can't find any estimates in the past few months.

Hi. New member signing in. This board appears to have a number of knowledgable as well as experienced individuals, so I'm looking forward to your input. To get down to it... I'm looking at subs. My car is a 2009 Mazda 3 sedan. I listen mainly to rock. Maybe throw in some hip hop. 90/10. I'll be working with approximately 500w RMS @ 2 ohms. My focus is SQ, and (like everyone seems to say) I enjoy listening at higher volumes. This will most likely be a sealed application. I'm comfortable sacrificing in the neighborhood of 1ft^3. I'm probably not experienced enough to call myself an audiophile, but I'm very critical of my equipment. I ask a lot from the products …

Pretty much decided on Fi for my next sub. Going for a single 12 in the trunk of a saab. The amp I have is an Elemental Designs Nine.1 with 1200 rms @ 1ohm or 900 rms @ 2ohm. Question is whether I should go with a BL and push the limits or underpower a BTL? I listen to mostly rap btw. Thanks for any insight!

My amp has a signal voltage adjustment range of 150mV - 5V (RCA Input). And my question is do I set the sub. output level from the MX-3 Bass controller to 5V? If it helps I have a RF T2500-1bd amp. Thanks for any response.

I am sending in my 12" bl and re-coning it into a 15 and i saw on the site that there is and extended lead time on the BL's so my question is will that still affect me since I am re-conning to a 15" and will be getting a new basket?

To nick or anyone else with the fi team. my invoice number is Invoice number: I-16248/00 I have been trying the last few days to change my order from a 18" bl to a 18" btl. Someone said they were gonna call me monday to help and they never did. Now today i got a ups shipping notice for the bl. i cant get anyone to respond to any of the emails ive been sending as of late. All i need is someone to help me change this or give me a refund. Please

hey everyone I am planning, on getting 2 12 inch fi btls n2s powered by two audio q 2200 amps. I am a begginer and was wondering if 180 amp alternator and 1 yellow top battery would be enough to power these two amps? Any help is highly appreciated

I have money to order a Sub finally. I always seen videos of people fi btls breaking every part of their car. My friend has a JL audio w7 2x 12". Im looking to go bigger and better. Although upon purchasing a FI BTL , there are so many types and ' add-ons +$'. I dont know what to get I want 1x Fi Btl 15" in a 2002 Ford Taurus SES. Anyhelp? What amp? Anything?

Since this is where I usually get replied to(I've only ever gotten one reply to an email) I figured I'd put this here. I know you guys are busy putting out the new BTL line, so I'm not faulting you here I just want to know: What is the status of my recone? It's been a month and I havn't gotten any word. And as far as I can tell your normal turn around is 2 weeks on recones. I packaged my motor well and included what I wanted done printed on a slip of paper, and even emailed you the same info. Name on the package/paper is Richard McCraw and it was from Pittsboro NC. Any info would be helpful, thanks guys.

Hey guys wanting to buy the 12" N2 looks bad ass. Just need some help with the box. Could somebody please give me some complete specs for the reccomened size the box should be. I am going to get a friend to build it lol. Thanks guys for any help. Rock on guys

I got my BTL 18 yesterday!! Funny thing is, I never got a tracking number.. As a matter of fact, I checked the invoice page on Fi's website yesterday morning and it still said "Your order is being processed." It still says that now that I've got it haha. Pictures coming up later today! If I wasn't at school I'd put em up right now. So to all people waiting for their Fi sub, don't be too discouraged. It could be at your doorstep when you get home today!

First off I don't intend to violate any copyright via design or brand infringement, I was just bored and really wanted to visualize what is coming next from Fi. That being said, I decided to share: I just want to know if the NSG is to be similar to the Ascendant Audio supergauss woofer, with N3 motors in anti-pole configuration. Theres some scaling issues, didn't bother with the heatsink (tho I am sure it is probably the most delicately designed feature in the BtL NSG), ignore the spider location... I really just wanted to see it in its glory, decided to use SolidWorks to whip up a model (I spend enough money renewing my license annually might as well use it right?). …

Hello everyone, pretty new to the forum but not a complete noob in car audio. I just had a q 12 installed in my EXT cab f150 hooked up to a hifonics brz17001.d. Unfortunately the brz is a faulty amp(not surprising) but in the process of getting a replacement. My question is to balance out my sound stage I am going to be putting in 4 new infinity kappa 5x7s(not set on them open to suggestions around the same price) and was hoping to throw a pair of tweeters in too. I was wondering should i go with a 4, 5, or 6 channel amp. I understand that if I want control of the fade and balance I need a 4 channel for the door speakers. But should i wire the pair of tweeters to the …

Steel is in hand..we will be working through the weekend coating parts and rolling along. Subs should start shipping on Tuesday in the order that they were received. Thanks!

Hello everyone. I'm in the process of building a small budget system and I want to get the Fi X 12" as my sub in a sealed enclosure. It will get power from Crescendo 1000C4(~500W bridged). I know that the recommended enclosure size ranges from 0.6-1.1 cuft but I don't know if I should go with a larger(1.158 cu ft.) sealed box or a smaller one(0.749 cu ft.). I listen to dubstep, rap(eminem) and rock. I want the sub to have good amount of output and produce good lows. Here are the enclosures that I'm looking at: http://www.sonicelectronix.com/item_7589_Sonic-Sub-Box-1H12-0.7-Gray.html http://www.sonicelectronix.com/item_7590_Sonic-Sub-Box-1H12-1.0-Black.html So which enclos…

Orders up through March 2nd are shipping today! Tomorrow orders through March 13th will be shipping. Thanks!

Just out of curiosity, what is the operating temperature of the magnets in the BTL N2. I'm sure Fi researched this, but I was just curious. From what I can gather, the operating temperature for ferrite magnets is around 300*C, but the operating temperatures for neodymium magnets is quite lower (source). What grade exactly is the magnets used in the N2? As in, is there a letter following the "N48"? I don't know exactly how hot the magnets get, but I read that voice coils can exceed 150*C. Thanks!
