Fi Technical

I'm looking at a BTL15, because I've heard good things. But until I get enough, I would probably be running 1 Sundown 1500d on the BTL15. If I got it optioned out, would it be able to handle a pair of strapped 1500d's? How much can a optioned daily driver BTL handle?

Ok I have read many posts and I think its something I will need. The Q cant take 2000w daily I dont think. I want to run my Autotek mm2000.1. If I buy the dual 1 and run in at 2 ohms the Q will get 1500 daily. I dont really compete, just little local shows. I think that much daily I should probably get the BP option just to be safe. Does it take away from SQ with the changes that are made? Am I better off selling my amp and buying something smaller?

ok, just installed my new 15qd2 with bp today. 4.8 cuft ported at 28 hz...rockford p1000-1bd. yes thing slams louder then i could have imagined. only one problem. i think i will be able to get rid of most of the trunk rattle, but it's the sunroof then driving me nuts. i need to get an sd card reader to load some pics and vids from my phone... every time i start playing some really low notes, the sunroof starts banging so bad that's about all i hear inside. anyone have this issue or know how to fix it? any ideas would be great! oh yes it's a 99' infiniti i30.

So I'm chosing to buy a FI BL18. Just two things I would like a bit of help on. First should I buy the FI BL18? I'm wanting a 18" sub, but I don't know how well this runs, I want to know from other peoples experience of how well this subwoofer is. Also i'm aiming for LSQ partly but don't want the rattling and horrible distorted bass sound. My friend is running a 7 year old sub (of course its old so makes up most of the problem) and it sounds pretty bad when he turns it up. I'm going to install this sub into my Chevy Tahoe in back behind the seat. Tell me if I should change anything but i'm deciding to do this. Dual 1 or Dual 2? (Be honest I don't know what the heck which …

ok guys, currently now I have an 18" BL fully loaded for daily. Its being powered by a JBL BP1200.1 at 1200 watts. Its in a 5 cu ft box tuned to 30Hz firing upward. The reason it is firing upward is because I cannot fit an 18" into my trunk rear facing. With a 15" though...I would be able to fit it rear firing into my trunk. So my question is...what sort of difference would i see? obviously i'd see a drop in ouput i'd imagine...but at the saem time, would it be noticable? Right now my BL is fully loaded for daily driving (daily option, flat wind, cooling). So at 1200 watts, even though its 200 over RMS, it isn't really pushing the sub to that much of its capability im gu…

I want to buy Q 10's. I am looking at ported box specs and there is a pretty wide range. I am looking for flat response and good SQ with a punch. I listen to metal and rap mostly depending on the day. They will each get 1000 watts in the trunk of Grand Prix. i was looking to do 28.75 sq inches of port for both, will that be enough, or will i benefit from upping it to 31.625

Hey guys i have 2 Btl's fully loaded each runnin off a zx2500.1. Each sub is dual 1 ohm and im looking to throw another 2500.1 on each. What possibilities do i have as far as ohm loads ill be seeing.

Hello, I'm lookin at getting an 18" BL, but my major problem is that my trunk is too short to fit an 18" sub in facing the rear of the car. So I came up with a slightly angled design that would shorten it by a couple of inches. My question, however, is if the basket of the sub will hit the bottom of the box at any part, since the sub is sitting at an angle. I drew up a diagram in Paint of the exact lengths and angles. Any input is greatly appreciated. Thanks in advance.

Hi, I currently have the SSD's w/ copper coil in about a cube sealed. My buddy had a box, 3.5 @ 32hz I believe, that he said I could use if I needed. Would that box be good for the SSD's or will it be too small? I could use the slight bump in output, unless the box is too small.

Well, here's the deal. I've been running my 15" Q in a sealed box for the last month or so and I am wanting to build a ported box for it sometime soon and need help getting a design together. I have no problem building stuff, I'm just no good at getting something together that will be right for my application (right ft^3, right port size, cut sizes, etc.). Below is a pic. of the largest outside dimensions I can possibly go with. The 4" rise is to clear the tranny hump (it's going in an ext. cab silverado.) I'm wanting something tuned to ~33 hz or so. If anyone can get together a design for me, that would be great. Just send me a PM or reply on here and we can go into fu…

I was wondering is doesnt have a size recommended for the 15 ssd in a sealed box? Is there a reaosn for this? would they sound good in a sealed box? If anyone is running them in a sealed box how many cubic feet do u have them in? I cant run them in a ported box because the box would be to big to fit in my civic, any help would be appreciated, thanks

Can someone tell me if this port size is right for what I want. Box size is 12.91 cubes after subs and port displacement. the port size is 23hx7wx14.56d = 32Hz. Is this right? 2-18'' Q's will be used in this box. Looking for it to hit really hard and will this box hit loud and hard? the subs will see about 6.45 cubes each. Is this box good for the Q's to hit really hard in?ready to build today....

I've been E-mailing Scott from Fi Audio back and forth but it usually takes a while for response and i realize hes bussy at the dB Drag World Finals. I desperately need these specifications for my Fi X 12s. LE in Mega Hertz- Z in Ohms- PE in watts- Ive been trying to get this info for weeks now so that i can finally build my box. I would really appreciate it if someone could help. Thanks, Ben

Scott we talked about you reconing a DD 2500 motor which has a 2.5" coil. Well i was woundering if you have any coils that will fit an Atomic AP/SPL gap? If so im going to send you an email with some more info. Just wanted to check with you before i picked up these other two motors. Corey

Hello all. I have just found out about Fi yesterday. Seems like a solid product. Everywhere I read everyone has positive things to say about them. I am in the market for new audio toys in my truck. Stumbled on this website and thought id ask some of you gurus about some suggestions. Some info for you. I have a 05' Single Cab Dodge Ram 1500. I have taken down some measurements of what the enclosure "could" be up to. I would like if possible a slight wedge box so I can still lean my passenger seat back a little. This is what I came up with. Length of box from side to side = 38" Height of box = 18" Bottom width = 11" Top width = 8" Ive done this calulation on Fosgates box …

Wondering on box size for strict SPL setup. Would it be best to use the 3 or 5 cubic foot box or some other size. Tuning will be 54 hz. Not sure on port size yet but thinking 150" per sub if I use the 5 cubic foot size and 90 on the 3 cubic foot size. Will be running 2 Sundown Audio SAZ-3000D to each sub off a 16 volt system. Willing to listen to suggestions.

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

Hey all, bought a 15" Q last night to mess around with and have some questions. Recommended enclosure is 2.8 to 4 cubes and tuning anywhere from 28 to 33. I need to figure out where in that range I should build. I listen to mostly metal, rock, blues/folk and on the rare occasion I'll crank some old school hip hop. I know kick drum is front stage and I will get flamed for this but I still like cutting my subs at 80 to get some impact for kicks out of them. I have a Kicker sx1250.1 that will be going on the Q so it will be just a bit over the rated limit of the woofer. It will be going in the back of my 07 extended cab F150. I toyed with the idea of going sealed but I …

is there a phone # I can reach someone at Fi to help me with a few questions about a box? Does anyone know?

I was wondering if you could possibly give me plans for a ported box for 1 fully loaded BTL 12" dual 1ohm sub. Powered by an Earthquake PHD10000d 3000 watt amp. My trunk dimensions are 36"L x 36"W x 17"H. here is the plans I got off a website. How does this look?

someone on another forum posted about more thiele parameters then wats on the site says he wants to know everything plus motor strenth can yu guys help out

Ive been looking for a "special" basket for my 05 15 XXX woofers for a while and i was wondering if FI would be able to help me out? I know all you guys use are the 12 spoke but i was wondering if you had anything different could make somethign different or knew where i could get something different? (other then the 12 spoke or the 6 spoke DD design) Im honestly in love with the last generation of the fosgate punch HX2 baskets but since its been some time since they sold that woofer i havent been able to pick any up.... So got anything for me scott?

Well yeh just like the title says i need some tinsels for a d1 Fully loaded BTL. I emailed a few days ago and but never got a reply. How much would they be shipped to 33027 Fl by sunday if possible
