Hello, first of all please excuse my english, I am from Romania. I just received a fi Q 15 ( no options ) and I am trying to calculate my speaker enclosure. I want to go for sealed enclosure because I don't have much space in the trunk ( BMM e46 sedan ). Recommendations for fi q box is 2-2.6 cu ft. With my calculations I am about 2.5 but I want to be sure I calculate it right before I give the blueprints to the box builder This is my result, I am happy because it fits inside the trunk perfectly. I made a dummy box to see how it will fit inside the car. Wood is 1 inch thick.

hey guys, i would like to know what you think of this box, im a some what noob/mid level at box building SUB- ssd12 basic with maybe a flatwire option AMP- rocksford t500.1bdcd, the birthsheet on this amp say it does 810watts at 1 ohm, which is what i will be running it at. here is the box http://s1244.photobucket.com/albums/gg580/ott9311/?action=view&current=a1_zpsf9dcb1d5.jpg please give me any input u would have, i listen to alot of rap/hip hop so im tuning for 33hz i know im prob under powering the sub, but i thought in a ported box you could under power it by a LITTLE bit. based on my above state facts, should i make the box any smaller or bigger? more or less po…

jl 12 w-0 4 ohm. can this be reconed?

Can someone give me the screw hole diameter of the 15" Fi BL? I saw the outer diameter was 15.625" but did not see a screw hole diameter. I am working with limited height and don't want the screws to be lined up on one of the boxes wall. Hoping I can save around a 0.5" inch on the height just having the outer surround overlay on the outer 3/4" edge of the box. Thank you for any help! I would measure it myself but I am ordering the woofer in the next few days and want to start the build now.

Here is the box i am gonna build to wall my Civic up..Let me know how it should match up with 2 Fully loaded daily 15 BL's. http://www.subwoofertools.com/forum/ported...mp;Fs=&CE=0

Got 2-12" BTLs the old versions. Im trying to make up my mind on what to power them with between a AT-5000.1D or the AT-7000.1D. Its only going to be a daily blowthrough in a '97 Thunderbird. Which do u think I aught to go with? If I went with the 5K Id be saving needed space due to less batteries. If I went with the 7K its a $400 difference in price and Id have to get an extra rear battery on top of the ones I already plan to run.

Would any one happen to know the diameter for the BL 15.

Need help with box specs and design for an 18btl. It will be going into a 2002 jeep grand cherokee. The space that I have available is 40x23x16 (w,d,h). I want the box to be tuned to @30hz. Sub will be powered by a planet audio bb2400.1 I would like the sub to be facing up with port firing back. Any input that you guys can give me would be greatly appreciated.

I'm looking for specs pertaining to a STRICTLY SPL setup using two BL 18's. What should the port be tuned to? How much airpsace do you recommend if I'm using a single chamber and acoustic coupling?

I just got rid of my suv and bought a car and I plan on putting my Q in my car but don't want to use the same box because it's just too big. Right now it's in 2.5 cubes at 32. I was thinking about going sealed for SQ but then again I want it to be loud enough for the sound to come from the trunk into the cabin of the car. I'm a low end feind, so I definitely want the lows. For a mixture of SQ and SPL while retaining some trunk space I was thinking 1.8cuft (FI recommended minimum) tuned low to like 28-30. How would this work compared to going sealed in 1.5 cubes?

Hey everyone i am interested in buying a Fi BL 15 and i have a chevy s10 ext. cab. My approximate space is 48" length, 17" depth, and anywhere from 17" to 28" height I have a few questions and would be happy with any answers anyone can give me.... 1. I am thinking about building my own box at 4 cubic ft. tuned at 32 or 33 hz, but i do not know how to correctly port a box. anyone that could help talk me through that would be appreciated. 2. An option i was thinking was facing sub forward but i didnt know with 17" depth if i would have enough space between the box and the magnet. (Mounting depth for Fi BL 15 is 8.250") Also if i faced it forwards my depth area would shrink …

I really need a ported enclosure design for a 15" FI ssd. since it is going into a pretty small trunk the sub will have to face upwards. other than that i have no clue on to which way to face the port, what size the box should be .....................if it helps my trunk is only about 15" tall, so my box really cant exceed like 14" tall, wheel well to wheel well cant exceed 30" and same for the depth. I would greatly appreciate a nice design for it.

I'm going to run 2-18'' BTL's each in there own box with 2500 watts to each sub. I would like to know if 6 cubes each would be good for the power that i'm running or should the box be bigger to reach full xmax? And do you have to add the ports size to the size of the box or not? I know you add the sub displacement to the box so do you add the ports to??? Want to run 2-6'' Precision Ports pre sub tuned @32hz. Does this sound like it would work? Want LOUD DEEEEEEEEEP BASS. And what is the disp. of a fully load BTL? Any help would be great.

I just got a 1998 blazer (4 door) and transferred over my Sundown Audio SAE-1200D and 12" BL from my 99 grand am. The box is 2.5 cuft AFTER sub and port dislacement, tuned around 32-34hz (can't remember exactly off the top of my head) I have upgraded the BIG 3 with 1/0ga wire, ran conduit along the frame rail with 1/0ga to the amp. In my grand am I LOVED it, but now in the blazer it seems to be lacking... not sure what exactly, but it doesn't seem to rattle my noggin like it did in the grand am. My question is should I look at building another enclosure that would work better for the blazer? If so, how many cuft? tuned to? how should the sub and port face? Or is the blaz…

Hey everybody I have a Fi Bl D2 and i want it to play off a 1 ohm load off a RF P1000-1BD. I have and idea on how to do it but i need to be sure...

I will be running 2-18'' BTL's off of 2-MTX TE4001D's. I would like to know if this power setup is good for what I need to run my amps. Yollew top for the starter with a 200 amp alternator, 200 amp isolator, and 2 yellow tops in the rear for the sub amps. How would I wire the 2 yellow tops in the rear. + to + and - to - ? Ground each battery or only 1? Any help with this would be great and where and what battery,alternator,or isolator I should use? And what is the Big 3? Thanks Fi buddies...

Ok so im about to order 2 12" Fi Qs and just want to know what setup i should get. im thinkin on getting a JBL GTO14001 amp for it, is that ok? also... i need to know if i should get an extra battery or cap for it, if so what kind?

Hello, Today I pulled my Q12 from the box (Dual 2) and tested both voice coils. They seem to settle at about 1.4 to 1.5 ohm. Is this normal for a dual 2? *It has not seen power yet.

im redoing my room and i want the fi revolution picture you see when you first go to the website in high resolution cuz my teacher is gonna make me a laminated banner for my room and i cant seem to find a high quality picture or the picture anywhere for that matter i looked everywhere and cant find it and now im asking around is there a way i can get the picture emailed to me or someone know a website i can get the picture?

So I'm new to car stereo and was hoping yall could help me out. I've been doing alot of research on subs and have decided on a 15" BL for my tahoe. Im wondering if yall could help me make some decisions on which options to chose for the sub itself and what kind of amp i would need to power it. I'm looking for some pretty hard hitting bass at some points, and at others i just like some good sounds. Thank yall for looking and for your opinion.

I was told by other members of this forum to email Fi about this topic, which i did, but I have not got a reply and it's been about a month since i sent the message. Any chance Fi still has recones for D4 X 12's? Or should I invest in an Ascendant Assain? Also, its just the leads. I've replaced the leads on one of my D4 X's already so i know i could do it, but i cut through the cone getting the dustcap off. Maybe I could ship the sub to Fi to get it repaired since they deal with things like this all the time? I'm just exploring my options! Since it's been so long without my sub, I am willing to repair it myself again. All I will need is four leads and a dustcap. Depe…

i have a 15" btl fully loaded. i want to compete in bassrace and maybe just for spl burps wise. i have about 5 cubes to work with. i kind of want the box to move alot of air for shirt tricks and hair tricks. is it possible to get high numbers with the two i want to compete in and still move alot of air like others do with this sub. just curious
