i'm building two enclosures one sealed and one vented 3/4" mdf my dims are 17-18" high {could go either way a little bit more} 41" wide{also have room over the wheel wells if needed} depth as needed running off an saz 1500d i am looking for the best all around sound this will see all kinds of music at differing levels [daily driver, wife two kids} i'm not looking for every last .01 db but every once and awhile it will have to take a pounding would anyone be able to help me come up with a design for the ported ? any thoghts on the sealed, with those dims it will end up not very deep. is that a problem sound wise, with it being so slim and wide or should i make it more c…

I bought a ford supercrew yesterday..... about 3 weeks ago i bought 2 fi q 10s, i saw that it didnt require to much airspace for a ported. i went to a local box builder who makes awesome boxes and he laughed in my face when i told him ported is .6-1.2 well he said his not building and so im trying to get a plan b..... i found a site that has a 2.5 seat lift http://www.supercrewsound.com/commerce/pro...21&catId=52 and they make a sealed box that is .95 perside http://www.supercrewsound.com/commerce/pro...23&catId=58 i need some input if possible would this be good seat lift and the box sealed? r is there a way i can get this box and make it ported, that would be…

I know that posted t/s paremeters on ficaraudio.com are for the stock BTL with no options. would it be possible to get the t/s params for the common fully loaded BTL built for daily music? Just curious to see how it changes, and I know you guys will always say stick to recommended box design, but it would still help me to have the t/s params.

haven't been on here in a long time. i'm trying to run two of these, but i lonly have 2 cubes after displacement for each. i already built the box and i'm waiting on recones. it's tuned to about 37. just wondering if anyone tried btl 12's in the same size box and what you thought of it? oh btw amps are 2 t20001bd's. one to each woofer, dual 2 ohm woofers.

I have 2 12" Fi Q's and im probobly going to order a subthump box for them, because I hear subthump makes one of the best prefab boxes for Camaros and Trans-Ams. However, these boxes only have a total of about 2 cu. ft. and after diplacement that would only leave me about .85 cu. ft. per sub. These boxes dont take up the whole rear well though, so if you guys think it would be worth it, I could cut out part of the bottom of the box and add some space down there. Thanks, Ben

I was wondering what would be good to run either the 18" btl n3 or n2, i have the previous style btls which is still are awesome daily subwoofers @ 35hz for me, but i want to move up a little. Is the n3 a good daily subwoofer, and with the option of 5-7 spiders what would that alter, would the normal 5 spider be a better daily/music sub? if someone could answer that for me that be awesome. or is the N2 recommended because i see on smd that the n3 is more of a spl sub, the fs is 51 on n3 , and 34 on a n2. does that mean my box tuning will have too change or no? overall i just want to know if purchasing 2 N3's would be alright for daily purposes/ someday competition with …

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?

For my Alero trunk I'm eventually going to buy a BTL 18 D2 with daily/all options. This is the cheapest & loudest daily setup I can think of and I've drawn up a shizload of boxes. I want lots of bass but don't want to shell out for a huge amp, alt, and batts. Power will be maximum 2000-2200 watts @ 1ohm unless I can borrow a huge amp for burps if having 1 fully charged battery will git-r-done. I will buy 1 battery and upgrade the alt if I have to but nothing crazy. RE Enclosure Calculator 1" MDF with 1" double baffle and no other bracing besides rabbit joints which I still am not sure if to use .25". 37 width x 28.72 depth (29.72 with baffle) x 20.5 height Displacemen…

So i picked up my 18 inch btl with hiXM coil and cooling options(DAILY). Now for the amp. Normally i would say that i don't have the money for the SAZ-3000D, but i found it online refurbished for the same price that i can pick up the Rockford Fosgate t2001BD from sonicelectronix. I read a post from a guy who got the refurbished SAZ-3000D and he claimed that it was functionally perfect so i wouldn't mind purchasing it. both are about $560. I plan on doing all the elcetrical upgrades necessary for either of these amps (big 3, Kinetic hc2000, high output amp, all that good stuff) now my only concern is that my sub is the dual 2 ohm and i will be running it down to 1 ohm like…

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…

first system about 90% finish, would i need a dual 1 or 2 in this situation, dont wanna go 1 ohm strapped at all since they dont make HO alts for a 2002 deville yet, still looking... got a chamber t line built by rich that i,ve had for about a year now, 2 1500ds, 100.4 coming temp. highs i have arc audio fd6000 up front and kenwood excelon coaxils out back on a aura rpm4200 4 chan. clarion max675vd II for the headunit and a clarion equalizer. kicker kyperflex, kollosus 4 guage 4 chan on the way. no alt but i was told that the alts in the 02 devilles and dts really put out about 180-190 amps as told by ohio gen after they tested a few, also adding a powermaster also. thi…

2 18in btl's fully loaded 12 cuft tune 34hz Port wide 18.5 in height 5 in lenth 10 in That is 185 sq in 12 x 15.42 = 185.04 right? thanks

Went with 10" bl, cooled, RF t10001bd at 1 ohm, 1cf ported box, (which is tuned a little high, might take apart and add an L to the port to lengthen it and drop tuning a bit). Just bought a 200amp alt. 1/0 wire all around, 4awg on alt. Was wondering if i should go for a cap, read that independent testing puts this amp closer to 1500watts at 1 ohm and want plenty of aux power, for starting the car and what not. Also should I stuff the box? Been a while since i had bass in the car, but then nit was just a thrown together mismatch system with no regard to resistance on the amp or any other important factor for that matter..wanna do it right this time. Any advice is appreciat…

Robin (iamamp3pimp) was in the process of building me a 2.8^3 @ 35Hz box for my AA Chaos 15D2 when I had to sell the sub due to financial issues. My question is would a Fi BL15D2 run off my AP15001D work in this enclosure? Sub would have cooling, flatwind, and daily options. Looking to get decent lows and numbers out of this box, though sound is more important than numbers to me. Had the CHaos 15 in a similar box before with good results, just bumped up tuning on this new box from 30 to 35Hz trying to get a little better score than the 143.7 at 40Hz I got with the first box. Here is a pic of the first box, new box will be designed the same but built out of raw birch. Th…

was looking at ordering a Fi Q and saw this as a new option, are the leads between the spiders not standard on these subs anymore?

So after being bassless for months now my FI BL 12 is on its way. I drive a 240sx now so i do not have much trunk room, I need help with a box design that would be optimal for the sub. Thanks for the help in advance. Trunk Dimensions: Height Sloping from 20" - 17" at the back. Length: 15". Width: 36". Simplicity is key since i do not have access to many tools.

I am looking for a recone for an SSA Icon motor and was wondering if you could do it. I am looking for max SQ as it is going to be for home use with a pair of B&W DM603 speakers. I also need a basket, I am looking for a 12" recone and basket.

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!

I was wondering if 11.25 net tuned to 31hz and 166.25 square inches of port is too much for 4 fully loaded 12 inch BL subs running off of 6,000 watts of power?

I wanna do 2 15" subs (read Fi BL's) In the back of an 1990 Formula.........think it can be done without having a sealed box or a wall and still having a backseat?? God I hope so. J

Hey i was wondering if you guys could recone a Rockford Fosgate HE? I cant find any recone kits.

I have 2 mono amplifiers of the same kind and I have a dual 2 ohm sub. Is it possible to put each voice coil to each amp without hurting sub?

I am needing box plans for a FI.Q 12. I know I could probably go out and buy one, but I would rather build it myself. I am planning on making 1.3 cubes like recomended as optimal. I don't want just a square box though. I would like it to be 4 sided with a little slope in the front. I'm sure you know what I am talking about, I hope. Anyway if you could tell me the size height, depth1(bottom), depth2(top), width, and angle that the slopes on the front usually are, I would appreciate it very much.

I purchased a Fi Bl 15 Waiting on it in The mail (awaiting Fulfillment) and i am puting it in a 04 honda accord coupe i would like anywher from 3 to 4 cubic feet but being able to put in my trunk restricts the height it needs to be no more than 17 inches high can anyone help me with dimensions and or advice on how to come up with a precise enclosure build for my sub i would like to be tuned anywhere 30 to 35 htz it would be much appreciated

hi, im new to the forum and been looking through countless threads but cant come up with the best set up for myself. i would really appreciate everyone's help! i already got a system in my car but im not happy with the bass output (plus the subs are overpowered and keep going out). i mostly listen to rap/hip hop and want to be as loud as possible. currently, im running 2 boston acoustic g5 12s and 2 12" radiators off of a mtx 1501d. the enclosure is a custom install in my spare tire well which gives the 2 12s 1cf each, the radiators are separate. im thinking about replacing the 2 12s and the radiators with just 2 Q series 12s and i see that 1cf is enough but 1.3…
