I have an 12'' Fi Q coming soon and i needed a box and i dont have time to do one myself so i went to the local audio shop to ask him what would be the best option. The owner actually held the loudest street car for two years in a row fyi....but I drive an f150 and i have a spilt rear seat. I wanted to take out the smaller section and have the box in that area so it wouldnt take up room for my passengers. His plans for my box is to have the sub face the floor of my truck as well as the port facing the floor. It will eventually exit out the side (meaning the port). He says that it will have the right cubes and hz. He says that when the sub faces down, it will shorten the …

I am about to build a new box for my bl and I wanted to know if it would sound better with the sub facing up and the port facing the back door on my jeep or have the sub and port on the same side?

ok guys i have a RF BD1500, birthsheet 1740 @1ohm, would 2 12" Q's or 1 15" BL be louder?? or is it possible for that to move a BTL a sufficient amount?? and also could you tell me what options to go with please and finally if i get a duel 1 ohm, does that mean the amp sees it at .5 or 1 ohm? and the duel 2 at 1 or 2?

Does anyone own a 94-97 Honda Accord Sedan? And if so, do you have a 15'' BTL Sub? If by any chance you do, could you tell me how you made the box for your sub? 5 cf is a lot of space, and my trunk is big but I dont know if its possible or not while still keeping the back 2 seats in... Thanks, -Curt

I was just wondering if pictures and/or cut sheets would ever be available on the forum. At the very bottom of the Pinned BTL Enclosure Recommendations Thread it says that "Pictures and cut sheets for some enclosures [are] coming soon," however that has been up for many months now and I was wondering if they would ever be up. I just got my 12'' BTL reconed and am wanting a more simple design this time for my box, however I have not found any actual standard recommended designs posted up by Fi, and was just wondering if they would ever be made available. Thanks

how big of a box should i build for 2-12 btl? It will be powered by 2-40.1, i was thinking 4 cu at 35hz bad idea?

Well I just recently bought a Q and since I was eager to listen to it, I put it inside the only box I had. The current box is a sealed box with about .9 ft^3 after displacement. Since its on the smaller side I threw some polyfill in the box as well. Now I want to build a ported box and I honestly have no clue as to where begin. I read through several pages, and found some plans but they don't suit my needs. I also searched online for calculators and only came across the RE calculator. I don't know how accurate it is but it kind of gave me an idea how port length affects tuning frequency. I'm a little tight on space and have a maximum of 30"w x 16"h x 16"d. Matter…

I have 2 fully loaded BL 12's that are dual 2ohm and want to make them dual 1ohm. How hard is it to get them switched over? I have no skill at recone myself so do i need to send that back to FI? They are 3 months new.

how much would it be to recone a FI BL 18'' sub, like send it in and get it done? thanks chop

Is there like a list of subs that you guys can recone? or is it just american sizes? or what? Are there any rf's able to be reconed? or are they all foreign motors of some kind??<----T1's????? i want some ssd's soooooooooo bad but i need some $$$ and ive got 2 toasted T1's sittin here, jw wonderin if i can do anything with them instead of sending them to rf for $104 each plus shipping which is like $40 each, each way---- $400+ haha Thanks

Well i decided to see if my 15" Fi BL is working before i get my box so i installed it without the box... I wired it parallel and when i turned my car on to play some music I would say about 1 min smoke started to come out ... it wasnt very much smoke but i need to know if this is normal for a new sub to do that.. also the sub was getting hot... what could be the probelm??? :

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

My new box will be 4 cubes at 30hz, with sub up and port facing the tailgate in my blazer. (5 inchs port to tailgate) My running it with a sae-1200d So my question is, is this box too large?

I am loving those FI x specs, and it has a strong BL as well I wonder why these didn't sell as good as the others.. It almost seems like its a good as a subwoofer as a ssd but cheaper. Im no expert but looking at teh specs it has a stonger bl. more efficient, lower fs Did we miss out on one hell of a woofer? or I know I did. IT has a nice xmax as well.

I was looking into getting a btl 18” I was wondering which option would be better a dual one or dual two ohm subwoofer??? Thanks in advance

So I have a 10" Q I'll be running about 1000 rms to. What kind of box dimensions do you recommend. I bought a prefab box for $20 because I figured if it didn't work, oh well I'm out 20 bucks. Well, the Q is a little oversized for the box so I figured, well, might as well just build one. What dimensions should I build it if I plan to run the above mentioned power? Is the .6 cubes best or would it be better to have closer to 1?

I was told I can wire this in series to achieve 2ohms. But when I looked up a diagram for the wiring, it didn't make any sense. can someonen post a link of a good diagram? The amp is rated at 1200 watts @2ohms. rms. I figured this would be a perfect match for the Q. Thanks for the help.

Will tuning to 35hz be good for daily driving? Alot of people say that tuning is a little to high for a btl. What do you think?

I am looking to build an SPL box for two 15" Fi SSDs with copper coils... I am just going to switch out of my daily box to this box when I go to competitions... What size box, and tuning would be best? I have a '95 4-door Blazer it will be going in.. I was thinking something along the lines of 6ft^3 tuned to 45hz..

Recently I built a box that is 47 x 22 x 22 with the port slot it all comes out to about 9.3 cubes, i was wondering if any of the gurus could tell me if that entirely too much volume for 1 18" bl daily driver?

Hey guys. I plan on purchasing two 12" Fi BL's. I will be powering them with two NINe.1 amps.....those are my plans. any other suggestions for amps are welcome. But the NINe.1's fit my bugget perfectly. I need suggestions for a box.... Ive been messin around and came up with this box. I will 45 all of the corners and seal her up tight. Should this box pound alright, but still sound dec.?? thanks here's the link http://www.subwoofertools.com/forum/ported...;Fs=27&CE=0

Ok, so I was wondering. A 12 in it's largest recommended enclosure, or a 15 in its smallest recommended enclosure, which has the more potential to get louder? Playing around with ideas here. Thanks, ~Trevor

I had an enclosure built and waiting for it to arrive. I am impatient and wondering what you guys think about the demensions. I got a basic 12" Q D1. Sealed enclosure: Width= 14.75" Height= 12" Depth= 15" Which is said to be 1.27 cubic feet "net volume" I am planning on facing the sub upward toward the roof in the back seat of my truck

I got two 15 inch BLs and I would just like to know how to tune the enclosure port to 33 hz? Is there some sort of program that could show me how?
