General Fi

I had 2 15" alpine type r's and now im looking to get 2 15" FI BLs but i only have enough room to do them sealed... i cant find that extra room that pored boxes need. so can i keep 2 of them sealed? and how would they compare to the alpines?

Hi I would like to know if you guys ship to PR. Thanks, Daniel

SOOO just got N2 last night figured I would share pics with you guys and side by side shots of the n2 and gen 2 btl, lmk how you guys like the blacked out look on the N2 N2 left, gen 2 right Then heres my family portrait (minus my ole double stacked Q which is in my car) THANKS GOES OUT TO FI FOR AMAZING WOOFERS

built it in 2 weeks, still pretty rough, we expect to get more out of it soon!!!

I am looking for more SQ than anything, with some good output of course. I plan to run an old school Linear Power 8002SW to two of these possibly. Would they be underpowered? If you are not familiar with this monster of an amp then please do not respond.

Hello I ordered a Fi BL 15, 25 days ago and tomorrow makes it 15 days since I got the UPS Quantum View email. I was just wondering when I might expect to see my sub.

Ok so today my dual 1 SSD 18 stopped working for seemingly no reason during very low volume music. The sub is not frozen. I checked the sub with a battery and it did nothing, checked all wires etc. etc. I will check the coils on my multimeter when I get to work tomorrow. The box is build to the specs of the sub 7cu.ft. @ 32hz. Powered with a Fosgate t1500-bd (2ohms and very conservative gain). The coils look normal to me, not black or even dark in any way. Sub doesn't and never did smell like burnt coils. I'm thinking the coil's glue failed. I'm stumped on this really as I've been good to this sub and only had it for a few months. I hope Fi will take care of me and warran…

I now have my 2nd 18inch fully loaded btl, This time am planing to build it for my large home theater room setup powered by a home DIY amp that can produce 2.5kwrms. in our country we use 220vac. http://i165.photobucket.com/albums/u72/pilyo168/schematics/5000W_power_amplifier.jpg -------------------------------------------------------------- As for car design. From Fi tech recommends: Fi 
BTL 18 – Ported box we recommend using 5-8 cubic feet @ 30-35Hz tuning, you can tune a little higher if you wish but we recommend keeping it close to 32hz for a daily driver. Again the same 12-16 square inches of area applies per cubic foot of volume. ---------------------------------…

It can't possibly work

Before buying from a small new company, I want to people to chime in with their experiences with them. From buying to warranty claims to technical issues you might have had with them. Please give details of the good, bad and ugly.

I've seen the new Sundown amp (3500d) and I plan on buying it but I need to know one thing before I do. Can a btl fully loaded handle 3500+ rms for long periods of time without blowing??? Also will I get a 3db increase since thats almost double the btls rated power or not????

Congrats from all at Fi to tejcurrent for exemplifying what we like about this forum... friendly, helpful, and has no issue of beating the crap out of our products The $250 for "rebuilding the forum" goes to you. Let us know when you want to use it and well comp any products for you. Again... thanks for all the help on the forum.

well... I got a motor here (lmt motor) and it was sent to me unmagged.. can fi magnetize it for me? what would be the cost? dont need a recone or anything.. just this. thanks

Wondering if you could contact me or Corey Anderson in regards to a 02 XXX motor & recone. I know you've been crazy busy, but the sub was getting ready to be shipped before Finals & now no new updates. Thanks for any help! nate

Well after a few months of owning my Bl 12 I've learned that I won't buy a mainstream sub for myself ever again! I also won't ever build a box that isn't as good or better than the one that I built for this beast either! Its only seen a 1200w rms hifonics amp the time that I've owned it and I feel it could handle 2000w with proper crossover tuning. I ended up building a box which after bracing was really close to 2.45ft^3 and tuned to 30hz give or take a hertz(not sure if the port is "exactly" 2.5x12" and "exactly" 31.25" long). It gets much lower than the system in my s10 that is for sure! Although I do love the way it sounds down low, I'm missing the volume i had in…

hey guys, i ordered an 18in fi bl on the 20th and it's now the 23rd and it still says "awaiting payment" every time i check my order status. is this normal? how long should this process usually take? should i be concerned? any feedback on this whole process is greatly appreciated, thanks!

Its been awhile since I had good pair of 18s, and I just ordered 2 FI BL 18s with cooling and flatwind. That was by far my best pair of subs I have owned in the past and decided to go back with what I have had the best luck with. Going in a 2012 scion xb

I just ordered 4 of the X series 10's to replace a pair of Image Dynamics IDQ 12v2's. I am curious what size vented enclosures have worked well with them. Thanks!

Which subs would be a better replacement for these? http://www.edesignaudio.com/product_info.p...;products_id=37 Should i go for the BLs or BTLs. I wan't a kick ass Daily driver. This is my current set up>> http://www.edesignaudio.com/userinstall.php?id=37

Well I hit my first competition today in Mccomb, Ms..I had my 15" BL in the Trunk with the seats up..Just like I ride around with everyday. I hit a 140.9...in the passenger Kick panel with my passenger window down. Should I be discouraged or happy..I hated I couldn't use my own music and had to use the Usac Cd the guy provided me..Cause I didn't know my noter or that cd that they stuck in my deck...I think If I would have know my note I would have done better...Please give me some feedback..

I didn't know where to post this, but since I would be pairing it with a BTL, I posted it here but okay. I am still deciding on an amp. I was looking at a PA Bamf 5500d but I heard it really only will put out about 1500 watts at one ohm. So if thats true my better choices are the AQ2200d, and the Rockford Fosgate t2000 I notice everywhere that the RF runs for about 600-800$. At this fleamarket called Gibralter up here in Michigan, one of the guy says he'll sell it to me for 450$ So 280-300$ for the PA, 389$ for the AQ2200d, and supposedly 450$ for the RF 2000 What do you all think would be the best choice?

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