What do I sacrifice by choosing this option? and can I run 2k to my BL's if I pick this and the other power handling options?

Adrie Brahma MK I Motor can it be reconed from fi? thanks

Hey just wondering how (2) FI 12" Q's and (2) kicker 1000.1 will sound in a 3cuft total sealed box will sound? Thanks, John

Buddy of mine has 2 bl 18's ran off 1 sundown 2500d, he has them in slot port now in about 12.5 cubes gross. They sound decent, but dont really have the lows, and its tuned to 32hz. He wants new box with 4 6" aeros's in about 16 cubes net tuned to 32hz. How does this sound for size? I ran 2 bl 18's about 2 years ago off 2 sundown 1500d's in about 18 cubes net with slot port and they pounded the lows, and sounded perfect. I just havent done any builds with aero ports.

with 2K RMS should i go with a BL or a BTL ??? i hear most people run their BTL at like 4k rms or 3k rms and i would rather run a BTL if it wont be vastly underpowered....i was reading on the forum and i think it was tejcurrent who ran 2 18" BTL's off of 2 hifonics 2K RMS amps and hit right below 151. so if i ran 2k to a Bl would it get just as loud as 2k on a BTL ?

I will pass my phone number on si I can speak with you since I will not have access to a computer for most of the day I need to buy 4 15" BTL's fully loaded with the best SPL options I need them absolute latest by monday or tuesday or even wednesday morning next week for the 3x db drag in Niagara Falls Ontario on the 28 & 29th I also need t o talk to you about the coil configs and the options of the motors sorry i posted this in the wrong forum

Alright, im kind of tossing the idea around between two setups in the trunk of my Crown Vic. Setup one is (1) FI BTL N2 18" in 7 cubic feet net tuned to 32hz. Setup two is (2) FI BTL N2 15s in 8 cubic feet net tuned to 32hz. Here is my problem and question, the first setup with the single BTL will slide right in my trunk with no issues using the box design and cut sheet posted on this forum for it, but the second setup is the issue. Can I run the BTL 15s in a smaller box than 4 cubic feet net each and still get optimal performance? Id like to shrink the box and bump up the tuning to 34-35hz if thats possible. 3 to 3.5 cubic feet per sub would be a much easier fit for …

So I got a 15" Fi Q for Christmas. Everything else that I need for my system I have as well. The only thing that is missing is a subwoofer box. Originally to save some money I was gonna build my own sealed enclosure. But after talking to some of my friends and family I decided to get a professionally made box. Here's the problem though, the only site that I've managed to find is, www.klausaudio.com. And while the site looks great and the options for customizing your box is superb, they're not taking orders right now. (Or responding to my frickin e-mails...) So I wonder if you guys knew any other respected custom box dealers/makers. P.S. Since I want a sealed enclosure I w…

i was wondering if you guys would help me get my port lengths and areas down. i just reciveved my btl 18" yesterday and looking to build the box right now i am looking at having a 7 cu ft after displacemnet. i alos think i want it tuned to about 32 hz. i t will be square port

Hi, I am missing the spaced spider option, what happend to this? Is this option still avalible?

I am getting the 15" Q w/bp power but my amp is a profile ap2000 and only puts out 960 rms bridged at 4 ohms. How can I hook up another amp so that I have about 1500 rms going to the sub and also some new 6x8's that I will be putting in?

Does aero style ports still fall in the recommended 12-16 CBF range? Was thinking of a single 10" in a 6cbf loud daily tuned around 32-33 range or maybe 2x7" what do you guys think?

I ordered a re cone kit for a 15" RE SE 12 spoke basket/motor. I opted for the double spider option, internal leads, etc fully loaded. About how much power can this sub now handle? I did not see any specifications on the re cone page. Thanks for help in advance

alright so ive had my 12" bl and sundown saz 1500d in a 2 cuft box wired at 1 ohm for about a week now and its not as loud as i expected. its a great sub dont get me wrong but it really doesnt get loud unless i turn on my loudness control on my headunit to atleast low and turn my eq settings on super bass... but i thought i read somewhere that you should not do either of these things... i was checking out my box that i had custom built and the port area was only 3.5" x 4"... isnt this a little small? i thought the port area should be from 32-24 square inches since the box is 2 cuft. would this make my setup louder?

If someone could show me a cut sheet for 2 12" Fi BL's it'd be perfect. I took a look at the single 12" cut sheet but I would like one for 2, just so I'm sure on the demensions and what not. I'm a bit of a noob when it comes to building enclosure's so help would be appreciated!

Just wondering... Does the Hixm coil has better efficiency in comparison with the standard BTL coil?What are the pros and cons when using the first in SPL /power handling/output? Is there any signifficant difference in the subs sensitivity? A few days i have watched some tests on some new quad stacked motor subs and i wondered if it would make any difference if the coils were put a little higher than they originaly ought to be put (like 4-5 windings were out of the motor top instead of putting all the coil in the magnet gap)

Hey, this is my first post here at the SSA forum (oh whoopee ).... My question (YES, QUESTION!) concerns the tuning and enclosure sizing for the Fi Q18 D2! Firstly, I'm not too sure about the relationship between enclosure volume and tuning frequency. I did see the enclosure sticky, but am tuning differently than the sticky shows and am also not sure if the size stays the same for all tunings or not...I'm thinking it changes. I plan to tune to 16hz and wondered if 30ft

well like i stated on someone elses thread, my tinsel lead broke and i really felt the woofer didn't sound the same anymore. i was just looking at it and noticed that the surround is starting to crack around where it meets the cone. and i also need a terminal which i broke a long time ago. my question's.... do i order the recone an do it myself? never done it, so i'm kinda wanting to try it. do i send it back to fi and have them do it? i built a box for another guy in hawaii that has a btl and was wondering if they could do my tinsels like his? or, do i buy a new woofer, because shipping back and forth might be kinda pricey? any and all suggestions welcome and …

I have been looking at getting a fi bl 15 for my 2002 nissan sentra and was wondering if i could fit the box needed for this sub in my trunk? Also what options should i get i want the real low deep kinda bass? and what amp would be best for my budget i would like to stay under 500 for the amp and im not sure which would be best for me and where i dont have to do the big 3 any ideas or help would be great thanks

I own a 2003 Mustang GT, and am trying to get the best system I can in it. I have VERY limited trunk space and so chose a single fully loaded 12" BTL powered by a Kicker ZX2500.1 (2500 watts RMS into one channel @ 2 ohms). I also have a kinetic 2500 in the trunk. The trunk opening is too small to get any sized box thru so I'll be installing it thru the back seat. The opening is 13" high by 32" wide, and 28" deep. I'm looking for a ported box to get the most bang out of the sub. Anyone got the best design for the BTL with the max dimensions (13x32x28)? Thanks.

Hello guys, I am new to this site, and just getting back into car audio. I am planning to run a 15" Fi Q powered by a Cadence TXA-1000D. From what I have read I will benefit from a ported enclosure because I like to listen to rap and music of the like. I was planning on using a slot port enclosure because of the area required for these ports. I have used WinISD properly I believe and have gotten a 3.5 cf chamber tuned to 32 hertz. I used a port size of 3x16.5 and got a length of 29.35 inches. Does this sound remotely close? I also have a question based on sizing the box as I am having trouble fitting a box this size in my trunk along with two cadence amps while maintaini…

I am currently waiting on my q12 dual 2 to arrive, and it is going in my work van (E-150) Passenger Converted to cargo. I have a two fold question I would like it if the box were no more then 15" front to back considering the sub facing front. My current setup has the sub firing into the back of the drivers seat as this is where it is the most protected and less likely to be damaged. I wouldn't mind using the ported box cutsheet for a Q12 as shown but I would have to put legs on the "face" and set it up so it was downfiring at the floor in order be able to carry the amount of tools/cabinets I typically do. (I am a cabinet maker so I can build anything you can imagine …

I was going to oreder a 12' fi sticker for my truck but the shipping is 12.00!!! Why and how is the shipping that much??? Its a 0.76 lb sticker that costs 4 dollars. But 12 to ship somethings not adding up here.

hi i wanna buld a new box for my bl15 i have my 15 bl in a 3.25 cuft box right now, my question is if i make a biger box lets say 5 cuft after port and sub displacement would it get louder thant what i got??? i wanna know if its realy worth it building a biger box.

So im about to build my first ported box and i need a little help. My 15" bl will be getting 2000 watts and has cooling and flatwind options. This will be going into a 96 infiniti i30 (same as maxima) My goal is to have the best LSQ setup as possible leaning more towards spl. I think i want to tune ~35. If the box is 4 cubes with the tuning at 35, is a port size of 4W x 13h x 21.8L correct? Is that enough port area? And is that a good tuning for my goal? Also if i use 2 circular ports that are 4" in diameter and 10.5 inches long would that be enough port area and the right tuning? Thanks a lot -Rick
