Fi Technical

Ik that the Fi BTL is 2000 RMS and 4000 watt peak butt ive been reading some topics and some ppl are saying that the 4000 watt amp will be to power full and could ruin the cone

I have an FiQ 15 and it bottomed out on about 5 notes for less than 30 seconds due to faulty ground wire. I was just wondering if any permanent damage could have been done to the sub? It plays fine now after securing the ground wire, but i'm just waiting for something to pop.

what fi specifiacations (dual voice coil, hixm, etc) shoud i pair up with a 2600 rms hifonics?

Hello, I need help on the port volume. I have a 15" bl with a 1500.1 kicker mono amp and Will be building a 4 cubic foot box and would like it tuned to like 35 hz. I don't understand what 12-16 square inches per cubic foot means in the recomendations. I have always used/seen cubic inches for a port valume. so if someone could "please" help me out asap that would be great. Thanks alot. Farris.

i am planning to go with the following sealed box for a Fi Q 15".. would there be any issues with the sub being mounted so close to the edges? theres only 0.1875in. of clearance on the top and bottom of the sub/edge

Does anbody know anybody that can build a box for me and setup my system. I'm ordering 2 15" SSD Fi subs with copper coils and I'm getting a sundown 1500d amp. I have a 2006 trailblazer SS. I need it to be at least 7 cu ft. My main reson for this post is because I live in the dallas, tx area. Does anybody know anywhere I can get this done?

i'm looking for a speaker box plan for my fi bl 18. would this box work or should i go bigger? http://img35.imageshack.us/my.php?image=5c...hz62sqin6hk.png

alright guys i have just ordered a 18" btl 18 dual 2 ohm and was wondering what is the possible wiring options that i can run it at ( what ohm ) thanx.

I have 2 fi Q 15's (w/ BP Power) in a sealed enclosure (seperate chambers) in a 2000 dodge dakota. Each chamber is 2.5 cu.ft after all displacment. I have my gain set on my amp (AQ2200D) to 4 V the same as the output of my head unit (Pioneer AVH-P5050DVD). My bass boss is all the way down, and so is my subsonic filter. The max vol. on this unit is 40 but i usually listen to my music with the vol. set to about 24-26. I just installed the system about three days ago so am still "breaking in the subs." On my way to work lastnight, i could smell whats seemed to be something buring. All my bass levels are set to either 0 or normal. Is there any reason for this to happen. I kno…

for 2 SP4 18's what else does this box need? do i have any errors in my math? gross volume 19.48 port length 26 (+2.5" for kerf correction) 30hz tune 14.37 cubic feet net volume .38 displacement .52 woffer displacement 1 extra baffle port thickness .75" box wood 1" MDF 204.25" squared of port area with 1:2.26 ratio http://i.imgur.com/MFLyfWx.jpg]

iam building a box will 41 INCHES BY 21 INCHES BY 22 " be fine for the sub and how many cubic feet would that be thanks for any help !!

I have a Fi BTL 12 running with a rockford fosgate amp but I've been wondering what I'm supposed to set the frequency knob to on the amp near the gain.I think it goes between 80hz-300hz. I dunno.any info anyone?

so what would the difference be if u had 1 fi 18btl fully loaded daily running 4000watts rms or if you had 2 18bl's loaded running 4000watts i would imagine that the 2 bl's would be louder cause more air movement? i dunno i just got done reading the efficency post that was like 8 pages about 500watts to the btl or for that matter what db increases would you be looking at it you ran the btl18 at 2000watts rms vs 4000watts rms what are the sound characteristics between the btl and the bl ? if the recommended box size is 5-10 cubic feet does that mean that the 10 cu ft will hit lower take less power to get louder but can blow easier? and what would the difference be between …

my buddy has a 18 btl the old style 3 mag. we took it out one day and the tinsel has been slaping on the spider and put holes in them. the box its in is 4.5 cuft and tuned to 32hz with 1800watt on it. i glued some t-shirt on the spiders hoping it will help my main question is does the recone come like the new style with the tinsel under the spiders?

I have two MA XL15s that I want to recone. how do I go about doing that. Must I ship the subs to FI? here is a picture of the sub in case people don't remember them

I ordered my BTL's on July 28th and i got an email saying they accepted my pay pal and i got an invoice number. After that i got no tracking number or shipping confirmation. I waited about a week and decided to email them and i havent recieved any response... I tried "[email protected]" "[email protected]" "[email protected]" and "[email protected]" Any ideas on how to reach them?

Ok, well Im trying all I can do to get some cf out of the box that im making to go under my back seat of my truck... I have figured out I can get about .74 cf out of my box but i might be able to get another .1-.2 cf out of it.... If it stays at the .74 cf, what would that do to the sound? I can use polly fill in it also, would that help? And if i can manage to get it up to .8-.9 before displacement, how much better would that be because it will be a decent ammount of work to get those extra few tenths of a cf...

i am wanting to get the most spl i can i order a BL 18 inch sub i have a rockford power 10001 mono amp i am having the jb fisher place design my box and i needed to know what the best cuft size they said that 8cuft would probably be the best but they said i might want to post on this forum to make sure thats best

when people talk about tuning their ports to 33HZ and stuff is that based on the size of the port. Also could i run 2 12" SSD subs on a hifonics amp putttin out 1500RMS or should i get one that puts out 2000RMS.

Just trying to see if I can get this sub re-coned again because I cant order the re-cone from the site since its a 12 with the 4 inch coil. Hopefully someone from FI responds.

What do yall think about this http://www.subwoofertools.com/forum/ported...mp;Fs=&CE=0 Would you make any changes or is it feasible.

like the topic says im experimenting with my RE MT to see which coil amp combination will work best, so I would like to know thanx guys , and is there a longer version of the original dual 0.7(actual quad 1.4) coil ?? im in dire need of xmax to get louder... im hearing slapping when i get that sub moving alot( could i be bouncing off the dust cap? I dont think im bottoming out)... last time i ripped the coil right off of the spiders (quad stiff) that was with 4 ab 500.1 gain all the way down ( only got them to produce 75xx watts before sub exploded)or should I be using a different basket with 10" spiders? btw this is a 15" with 12 spoke basket

I'm pretty sure this isn't possible but, I was wondering if the Q series was universal. I have a Q10 D1 coils paired with a Sundown sae-1000D wired at 2ohms. I know that some of the subs you can change with a recone. Otherwise anyone know some magical way to get a 1ohm load on my amp haha.

Hey Scott, Les here i been trying to get in touch with you for a while now about the recone kits. Please get back to me ASAP i need them fast

Hey guys, I was running down some information to do a build for a buddy this weekend. He's looking to do a modest setup with 4-500 watts of power to the sub stage and would like to go with a pair of 10's. I showed him the 10" X's which he was very interested in after listening to my Q's he's quite impressed with Fi. One thing I noticed both here on the forum and on the website is that there's no Tech specs for that line. It's easy enough to post up here or send an email asking about the optimum tuning, enclosure size, etc. which we'd like to know, but I figured I'd just go ahead and ask when you might be expecting to have something up on that information? Also, I thi…
