General Fi

I had time to get things rolling, so the old style Xs are back up in D4 coil and 10" and 12" sizes. 10" D4 $65 ea 12" D4 $75 ea Starting with a cast aluminum basket for a rigid foundation, it uses a double stack motor with a 2” copper voice coil wound on a black anodized aluminum former. A poly cotton spider and curvilinear cone with multilayered foam surround keep things controlled under the toughest of conditions. Far from entry level, the Old School X Series provides deep, detailed, and powerful bass from both sealed and ported enclosures. 250W RMS and 16mm Xmax. Great subs in smaller systems or monsters in multiples for cheap Discounts of $5 per sub on orders of 2-…

After helping my father with my dying stepmother(cancer), she pasted away on July 9th, and I have been helping my dad with everything. But now I have time to spend helping Fi and Ascendant again. I'm sorry I was gone without a trace, but I was going threw the family thing. Im am back woriking for Fi and Ascendant on a part time basis, while going back to school. As soon as my Magnum SRT-8 demo vehicle is done, I will be going to dealers in the southern states. So just wanted to say "Hi" and "I'm back"!

Hi all, I'm new to this and been going by what my friend and his dad tell me but as their taste in music is different than mine I wanted to ask around. I drive a 03 s-10 xtrme ext cab and have 2 12's currently but they are horrid and was looking for something better. I list to alot of rock, metal but i also listen to quite a bit of hiphop/rap. I have a hifonics 2000watt amp and was wondering what size/series of speaker would work good for my taste in music and size of the truck that also work with the amp I already have.

Hello all, I've always been a fan of Fi since it came out just from reading the forums and when I first started wanting a system. That was about 3 years ago now I think. I would like to put together a system now but I'm shipping off to college so money is tight at this point in my life. I'm sure this is QUITE impossible but I'de like to not spend more than $500 on either 1-15 or 2-12s including the Amp. I don't have a deck either right now but hopefully can figure that into the budget sometime. Thank you for any suggestions or insight. -Rob

Just ordered a 12" Fi Q and I was curious as to how "Fi" is pronounced? Is it like: Figh (like high) OR Fee (like See) Just curious

Can i put a a sundown 3500d on a single 15 fi bl?

I went on a trip today and one of my subs stopped working. I noticed that one of the coils was no longer working. The coils were series so I just ran the one sub and eventually one of its coils stopped working also. I tested the coils with an ohm meter and each sub has a coil that reads open. Am I right that something like this is not covered under warranty? I am not really sure why the coil opened up since I was probably giving the subs no more than 1500 watts between the two. I also have a voltage meter in my car and noticed that my voltages stayed around 14 volts when the first one blew while on the highway. These subs are dual 1 ohm coils and I am powering them…

These are my measurements now... 15hx33dx36w I was wondering if it is possible to fit the 18" Bl tuned to around 32hz in my trunk. and what would be the best setup, sub firing into cabin, port back?? Need ideas for the enclosure. I am going to run it on a saz-1500d. I did at one time have a L7 in a 6.0^3 box. It fit just fine. any help is apreciated! i put the new measurements up, i went out there and measure it out, width between strut towers. height was at the trunk tensioners and depth was just depth... keep in mind i have the trunk lid hinges to clear......

Hey guys we will have the new X series up for Black Friday, as well as some other things! So keep a lookout! -Shawn

Hi there i have an 18" BTL the older style one with the tripple magnet and while taking out the whole system so i could design a new box i pulled out the sub from the old box and spotted that the spider on the btl was ripped in about 2-3 places 1 of them being a noticeable rip and the other 2 look like there about to rip and also i found out that where the spider is glued to the cone the spider was coming unglued in a few places. I wanted to know does this mean that i need a re-cone or is it salvageable, pictures are below, the pictures below are of the major rip one Thanks

Well sorry it took so long to post, but I've had poblems with my log in and had to redo another one. Scott, I had some trouble getting ahold of you at first because you had no phone number. I am glad I waited, Thank you for responding to me about the subs and getting them made and shipped to me in a rush. Thanks bro.... you'll have another order for two more subs in just a bit. On the weekend of March 3-4 we went out to spring break jam and took 1st place with RXZILLA with a 156.2 and took the world record at 151.3 in the Pro-stock 0-600 class. Not too many people knew about FI AUDIO but after that run....everyone was refreshed about your product. Thanks again Scott. A s…

why cant i post pics? Sorry, dynamic pages in the tags are not allowed whats that supposed to mean?

just wanted to know what would be best from you guys wether i went with a single btl 18" or 15" for my car (1998 buick century) im confused. my custom box is already paid for my installer needs my car for a whole day so i still got time to pick the right sub for my car im just confused

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!

i ordered a btl about a month ago and its status has been awaiting fullfillment this whole thime. I have not got any emails or updates on my sub and in my account it says i have no completed orders with fi audio but the mony has been taken out of my bank account. has anyone had a problem simmilar to this? also i cannot get any return e mails or messages on my order. any help would be apreciated. thank you.

Still have heard nothing other than what's in that thread. Someone get back to me, this is getting a little rediculous

I am about to order a recone for one of my 2005' XXXs and had a few questions about the recone itself. I know you have reconed alot of these woofers over the years and was wondering if you change the recone composition at all(besides your cone) when compared to the stock XXX composition? Will the woofer still have it's 1500-1600rms capability? Will the recommended enclosure change at all? I was able to effectively salvage the original XXX full face dust cap. Can it be re-used with your recone? In addition to the woofer I am about to recone, I received another misaligned 2005' XXX motor in the purchase. Do you have the ability to re-align the motor and would you be willing…

i got a 12" Fi iB3 and i need a recommendation of an enclosure help will be appreciated Thank you!

Just some piccy's of my box build. 1.2 cubes ported at 35 hz. Haven't figured out if I'm going to do a slot or a round port. I've done the calcs for both in winISD and I'm ready to do whichever one is easier. Trusty table saw! And a piece of wood. Stack of wood and toolboxes... My blue prints. I am a engineer, after all! This is where its at right now. I'm thinking about the port and whatnot. The top will be skinned with a 1/8th wood, I forget what it's called at the moment, it's in some of the pictures. It'll have foam on top and covered with black vinyl, it's the new center console in my pickup. Sub placement will be a little different, but when I get to that…

hey guys.. new to the site, and ive been out of car aurdio for about 10-15 years... im from the days of orion amps on strokers LOL i have a 63 impala and im going to build a box or get one built for the area in the trunk under the package tray.. its very important to me that you cannot see the sub itself, or the amp the area i have to work with is about 10.5"tall x 26" x 26" give or take, im gonna get better measurements today in the interest of $$$ and all, i want to atleast use the amp i have now to get started... its in my daily now cause i got bored and a friend gave me his old 12" cvrs in a kicker ported box for $50 LOL.. its a old school MTX thunder 2150x .. it pu…

So, this morning at around 7AM, i get into my car, turn up the volume, and no bass. The sub wasnt playing at all. the lights on the amp were on, but i drive for like 15 minutes, still nothing. after 7 hours after school, i go to drive home, and still nothing, about half way home, BOOM the bass kicks in, just as loud as normal, no abnormalities. what could have caused this? ive had the setup installed for a week or so. 1 15" FI BTL Hifonics bxi-2608D Alpine IDA X100 headunit i have NOT checked ALL connections yet, but what else could it have been, it hasn't happened again yet. I will get a lot more concerned once it happens again, but right now, im not too worried.

i been looking at this forum for a while know and i see a lot of people asking to get a recone. is it users fault or is their something wrong with the series of sub?. most people say this about the Btl im

i got a BL 18 with dual 1s and might be getting a sundown sax-1200D so do you think running it at .35 ohms is safe?
