General Fi

Edit: The option is up on the site. It is an extra $50 to go to the 4" coil. Brings RMS power handling up to 1500W per sub. We were sitting on this one until after the new year, but have decided to release it now given the amount of inquiries we have had regarding 4" coiled subs. We will be adding a 4" coil option to the BL Series by the end of the week. This allows for more thermal capacity over the standard 3" coil. Spec wise it does change things some, but enclosure recommendations will remain the same. In testing (about 9 months back and again last week) we saw some solid gains in the mid band with similar output near tuning to the 3" coiled version. The midban…

Can someone please explain the Internal Lead option to me and tell me if it's worth the extra $25? I looked in the tech section but the Internal Lead option doesn't seem to be explained in there for some reason. Any help is greatly appreciated.

It looks as if we have reached the end of an era. The BTL is no longer on the Fi website. Yes, Fi has a website. Lets take a moment and share our favorite BTL experience. My first BTLs were/are the N2 version. I've still yet to try them out in a car, but I have re-coned one of them. It was my first re-cone. Unlike other Fi re-cone stories. My re-cone showed up unexpectedly a week after the order was placed. The glue, which I order after the re-cone, took 2 months to arrive. I did run them in my home theater for a while. The got the job done, no problem. I cant wait to see what they do in my car. Farewell BTL, you will be missed.

Need help finding a good reliable h/o alternator, I'm currently in Iraq. I drive a 2002 ford expedition with a stock alternator, and im getting 4 15" icons in a ported box either powered by a sundown 4500.1 or two sundown 2000d, So whats a good size alternator that i should get and what brand do yall recommend? Thanks!

Sad that the windshield imploded before I could get a full burp out of it and show what it can really do maybe next time. So far I have had a IASCA and now a USACi SQ judge say they have never heard music so loud and so clean. Makes me smile all this hard work and tweeking is coming around. Also you will notice I did closed up scores Next time I will do it the official USACi way. Look at the scope below, I was just getting it starting to ramp up when I noticed the window let go.

I have been looking around and I was curious to see some pictures inside the FI facility? Scott or Nick do you have any cool pics of the place? I think it would be cool to see it.

I just receieved 3 out of 4 of my BTL N2 15s. First, I'd like to say they're super sexy! (even if they do look small next to my BTL 18s lol) I'm just wondering if there is a delay or if I can get at ETA on my fourth sub?

Now that we have established the new direction we are taking with the trying to re-iterate the importance of having manufacturing (instead of manu-packering) here in the states it reminded me of something I learned of in history class years ago. FDR was famous for his "Fireside Chat's" back in the days of nothing but a radio to talk to the people on a personal level...so this is what we are going to do. Join us in the chat Wednesday nights at 7pm Pacific time (10pm eastern). We'll be having random contests and give away things while we are live in the chat. If you have some technical questions we definitely don't mind helping you out. Scott and I will be on there and try …

Just a short story, i thought I would share. Im not expert, but i try to keep my mouth shut. However, i always run into kids who know nothing, but like to run there mouths like they do. So anyways, I went to the bank to drop of a deposit and then stopped at the mobile to get some cigs. As im coming out, theres this kid in a Tracker parked right next to me. I mean i have to squeeze in my door hes so close. So i go to hop in the jeep and he says yo dawg whats up. Im pretty friendly so I made small talk with him. Anyways, he finally says, so you want to buy a system or know anyone who does. And I said nah, im not really into that chit hoping to get off the subject. So …

i was just wondering if you can still get the older style btl's?

Hey guys. I sent in 2 12" Qs (older double stack mags) and that was a few weeks ago to get recones to D1s... I got an email from UPS saying they would be here last wednesday. Just wondering if I could get an update? My name is Jonathan Bowers. I asked for the black Fi dustcaps. I have sent you guys a coupl emails. But no response. I know you guys are busy, so I figured I post here. Thanks Nick and everyone else at Fi. Jonathan

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!

I love the fi sub line up, the only thing i don't like is the outdated dust cap. Hate to say it but the domed dust caps just look ugly. The visible glue, the rough cone material combined with the dome cap make the sub unrepresentable. Do you guys ever think you would come out with dish style dust caps that cover the whole cone? maybe in the blueprint line up? I plan on purchasing a ssd15 in the near future and just hoping you'll offer dish caps, or mybe i'll just wait for the blueprint subs and check them out.

here are some fi wallpapers I made, not the best, but there aren't many Fi backgrounds so I guess this is better than nothing. I used to have them in another forum but they got deleted, hopefully they'll stay here.

Welcome FI !

My new SP4 18 reads 2.2 ohm on both coils Fluke Dmm leads touched it reads 0.1 the Sub reads 2.3 ohm Craftsman DMM leads Touched it reads 0.0 the sub reads 2.2 Cheap harbor freight meter leads touched it reads 0.1 The sub reads 2.2 My other two SP4's Both read 1.4 ohm. I have been waiting on a response from FI Car audio. I Hope they come through and fix this. Anyone have this issue too?

The 2010 FI Q 10" just arrived. It is definitely heavier than I was expecting but looks really good. I guess I can start building my custom sealed box soon. I haven't figured out how I will attach a grill to it yet. The 28mm Xmax and the fact that the cone sits higher than the lip will produce a challenge to protect the subwoofer. The only thing that pissed me off is that FI shipped the subwoofer using UPS. $60US shipping to Canada and then $92CAN for Brokerage and Customs. This is why I try and get everything via USPS.

I HAD A POST UP TO RUN 4 FI 18" BTL'S FULLY LOADED. WITH A LOT OF DISCUSSION AND DEBATE I MOVED DOWN TO THE BL SERIES. I HAVE ONE COMING ON THURSDAY AND I WANT TO KNOW HOW MANY BATTERIES DO I NEED. HOW MUCH POWER. WHAT KIND(S) OF ALTERNATOR(S) DO I NEED. WHERE DO I FIND A DIGITAL VOLT METER THAT IS IN THE SHAPE OF A SQUARE THAT HAS BLUE NUMBERS? WHERE SHOULD I PUT THE PORT IN THE BOX FOR ALL 4 SUBS. SHOULD I HAVE ONE OR MORE PORTS. STRAPPED AMPS OR NOT? EPICENTER OR NOT? EQ OR NOT? HOW MANY 6X9'S SHOULD I GET. HOW MUCH DYNOMAT, DAMPLIFIER, OR SOUND DEADENER. I STILL HAVE THE 1994 CHEVY SUBURBAN 4WD.WHAT KIND OF AMP SHOULD I PUT MY 6X9'S TO. AND I WANT THAT BUTTON THAT MEA…

I just got done setting my gains with the DMM, my main issue and area of concern is the subwoofer and the Hifonics Bxi1606d amplifier. The component set is working and sounding fine and so is the Sundown SAX 100.2 amplifier. The Hifonics amplifier and subwoofer on the other hand are just being a pain in the ass to get sounding decent. To give you all the information I can on the subject we'll start here. I want that 15" Fi Q sound that we see and hear in videos, the smooth rumbling bass on all frequencies, well-reproduced, very loud, and sounding very good. To achieve this I have done the following. I had the following set on my amplifier and head unit. Amplifier: SSF: 25…

what is the average wait time to receive the subwoofer when you place a order. I ordered my sub Nov. 3rd and it still says " awaiting fulfillment "

Hi i was wondering if anybody out there know what would be a better subwoofer, i own a t215d2 rockford fosgate paid 450 for it sound really good , i was tinking of getting another sub but i wasnt sure if to get another t215d2 since ive been told that they are overpriced this guy sugested me a fi bl 15 fully loaded price is 344 shipped, but im now sure do u guys think that the fi bl15 can keep up with my t2 if not please list some brand and models aout ther that could thanks :Touched by NDMstang65: Sorry if this looks choppy guys, but i merged all of his threads into this one. Moral of the story, don't mix subs.

Ok I've never put any sound in any of my cars in the past. I went out one night with friends I was able to ride in an SUV with a decent set-up (from what I experienced) and that got me interested. I have a 30-40min ride to work each day and my OEM speakers are going out so I've been doing my research... From what I've read Fi subs have been given great reviews and the only complaints are due to the lead time on getting them. The set up (in my friend's SUV) that I liked was 2 10" JL w7s in a ported box on a 500w JL amp from what I was told. I prefer sound quality over loudness and won't be going crazy loud. The thing I did like was the fact that I "felt" the bass but the c…

I have a motor from an older eclipse titanium (88120ti), which I believe is a 3hp. It has a 6 bolt pattern, which fi uses, and I want to buy a 15" recone kit from them. I want the sub to be able to have flat freq. response from about 25hz up. I want to use a ported box tuned to about 3cu@28hz. I want the sub to pound on the bass tracks (rap), but also groove on tracks with a bass guitar (r&b,jazz, some rock). If I can get the money, I plan on powering it with an eclipse da7232. So my question, can this be accomplished with this motor and fi soft parts? Also, how big of a difference is there between a ported 15 and a sealed 18?
