Fi Technical

I need to get my box done before my subs get here. So I need to know how deep to cut so the subs will be flush mounted. Does anyone have that info or have a bl to check for me. Thanks

i am getting a 15" Fi Audio SSD15 sub and i am wondering what amp i should get. i dont know if i should get one with 800 rms or 1000 rms. also, what are the best specs for this sub? Also, will i have to do the big 3 or anything else to handle this wattage? i have 98 navigator. thanks!

Without going over my windows and taking the whole back up, i have 40" D x 46" W x 22" H, which is 11.8 cubes gross, will that be enough for 2 BL 18's? It says to use 5-10 cubes each, thats a wide range, i guess depending on power to them mostly. I will be running 2 saz1500d's strapped to them. I have more room than that if needed, just want to leave a little space for batteries and amps.

Hello, I recently purchased an Fi Q 10" and have it in a .6^3ft sealed box (Before displacement). I am running it off an Alphasonik PMA1200D @ 4ohms (approx. 1200 watts) and I notice that the output seems to be really low and kind of dissapointing. It seems to get any real output the gains have to be turned very high along with the bass boost (which of course in not what you want to do). At this point I am not sure if I should try it in a ported enclosure or if something could be wrong with my amp perhaps. Has anyone else had any of these issues? Any suggestions? Thanks, Jim

right now i have a alpine i got from a guy and i dont know much about it its a alpine mrv-t303 but i want a new one and i was wanting to know which kind would be best a link to one online would be great

Just what the topic says, i need to know the diameter of a BL 12 magnet.

Before anything, how much power will a Q with BP cooling handle, if gains are set properly, no audible clipping, etc.? Okay, first off, the SSD should be louder then the Q, IN THEORY (disregard the box and everything), due to it's higher sensitivity, correct? Second, the SSD is known to be heavy on the low end bass, but a bit lacking in the higher freqs. How does the Q do? Will the Q slam as hard as the SSD? In other words, will the Q reach that ass-dragging low bass that rap music is typical of? Thanks, I'm going to ask a couple more questions based upon the answers I receive to this, so check back. -SteveSan

I am kinda worried about something damaging my Q. It is going to be firing upward, toward the roof of my tacoma in the extra cab. But i don't want it to be in the way of the sub (excursion)

okay, so i've got a fi btl 12 fully loaded. but i dont know which amp to put on it, i want to use it for daily driving but also be able to put up some numbers in the spl comps please help me out thanks

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 am going to be building a new box for my 15 inch q because my current one is a little too big. The dimensions I am working with are 14high, 32 long, 20 inches deep. I am having a hard time understanding what size slot port would it take for this box to be tuned to 33hz. Since I will be going with sub up+port up, the port can be either 30.5 or 18.5 inches long(depending on if make it long ways , or short ways) but how wide, and long should it be? (would like to face them back but they will be too close to the back of the trunk....I can also face them forward). Also, current box is 14x32x24 tuned to 33hz....will I see a huge decrease in output with this smaller box?

Im just hopin that someone can help me out with gettin the info to order a FI Sub i have a alpine type x and it aint the bass im looking for and ive been watching steve meade and its just WOW!!! and a guy came by my school (Mobile Technical Training) with two 12's and it made the whole car shake i even have a video of it but yea i live in the Virgin Islands and i would like to know how much would it cost and if its possible for me to get it cause i really want one, thanks to anyone who can help me with this.

So my buddy has the newest version of the 12" Type R that he wants to upgrade. Here's the details, and hopefully I can give enough info. He has an ONX1.1500. He also has EQ'ing at 30, 45, 60, and I think 80hz. We'll make a ported box, but it'll need to be on the smaller side, maybe 3-3.5ft^3 net. His Type R is tuned to 33hz at ~1.5ft^3 net, I know that's not the only way to judge things, but he may want to go a bit lower on tuning frequency, maybe 28-30hz (this is in a 2000 Explorer btw, and any port frequency opinions for this sub are definitely appreciated). This dude needs a tough sub, he can be hard on stuff He wants loud, and if he goes on a trip, he may play the su…

Ordering one x12 4 ohm sub today with BP Power option. It will be running in the 320 to 400 watt range. The specs call for a box .6 to 1.1 cuft. Why is there such a range and what is the difference if i built a box at .6 cuft versus building it at 1.1cuft? I have the room to build it to the max dimensions, just would like some more info? How do I figure out exactly what size I need to make it sound great? I listen to mostly older rock, 70's and 80's, but some newer stuff to as well as a little rap if it is a good song.

Guys, I know the BTL enclosure recommendation for the 15" BTL is 3-5 cubes net, however I also know that required volume is also dependent on power supplied. I was wanting to know if there would be any problems with running (3) 15" BTL's in a 8 cube net shared chamber enclosure? I should have roughly 3500 watts on tap for each sub, but I will not submit them to that much power, I was just wondering what I could get away with in terms of enclosure size? This is a daily beater.

ideally, what would be a good power range for the ib3 12 inch sub?

the actual diameter of the BL 18? need to see how im going to have to design my box

hi im about to order a bl which im gonna use for my daily setup. but i also wanted to use it for spl comps locally so i wanted to make 2 different boxes. i have a mini van so size is not a concern i can make a box in the back as big as 20 cubes. so can u guys help me w/ measurements and stuff??

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 a 12'' Q dual 2 ohm and it will be wired down to one ohm. I have a hifonics bxi1208d powering it. I wanna make sure i get my settings right on my amp. Where should i set the SSF at and the low pass at? Also since my HU has 4 volt output, should i set my level to 4 volt? As for the box, what hz should i have it tuned to. I listen to mainly rap and deathmetal...yeah i know complete opposites haha any suggestions will be greatly appreciated :)

I'm only going to be running around 700 - 1100 watts rms to the sub when playing music. Probally no more than 10 min sessions. And the sub will probally move no more than 3/8 of an inch in excursion each way. Will I have any problems with this small amonunt of excursion?

Hey guys! as of a few hours ago, i ordered a 15" BL and a Sundown SAZ-1000d amp! I was just wondering how you guys think this will sound! and suggestions on my box. I want to make it ported offcourse

Its almost time and Planning has started. I still need to find out if I can make a slot port work if not maybe two square or even aero ports. Suppose will have to do some maths and cross-checks. Draft box (not to scale) Let me know what you think.

Ok so i got a 18" BL Fully loaded and i was wondering if 1600 watts is not enough if someone could tell me that would be nice thanks.

Looking for some help designing a new box for my sub. I listen to a lot of rock/metal, but I do like rap and would like to be pretty loud. Any help with sub placement, volume, what to tune it to would be great. also it is in a blazer. As of now its in a sealed box around 2.6 cube with a Hifonics 1208d and i know it has so much more potential. Thanks and if any other info is need please let me know
