General Fi

i just recieved my FI Q 10 and i am currently looking at a sealed box with .65 cuft before sub will this be ok? i am pushing 1100 w to it easy on the gain. any help or opinions would be appreciated

Ok guys. The time is coming up fast to kick off my build. However, I had a few last minute worries (still designing a box) and was curious. I am still debating if I wanna build a box so I can slide it between the wheel wells for real quick sub "fixes" if I must, but am still not sure, what do you think? I want to compete in SPL comps, so I wanna make sure I do this right, lol. How much of a difference would I notice if I went with 2 15" BTLs over 4 12" BLs? With 2 15's the box would just be soooo much easier to design, and I think I am worried about fudging something with the 4 12's. sigh, I need a little help plz, guidance, anything.

Looking for some dimensions for a 15Q. It will be powered by a sundown saz-1000d. Its going into a 2008 scion xb. I would say I have about 2'x2'x4' area to work with. According to specs it should be 2-2.5 cubic feet. So probably stay around the 2.5 to account for displacement. I know you guys are miracle workers. I tried to remember to put as much info as possible I know people leave stuff out all the time.

Hey guys, i need help with a box design and unfortunately im strapped on time. If someone could help me out with some plans with these specs i would be greatly in debt. Box is for 2 12's ( .15 displacement per) tuned to 32hz - slot port centered on box double baffle 3.6 cubic ft total 36w x 16h x ??d I need the width and height to stay at 36 and 16. I tried using subwoofertools.com but the program wouldn't give me 36x16x?? but rather 32.5 x 16 x 23.5 or something. Once again if someone could help it would be greatly appreciated.

Where can I get some?

Just need to know which port placement would be best

So i'm in the middle of building my box, i used torres tuning calculator along with sketchup to design the box, i'm 98% done with it and realized that my Hz may change due to the fact i'm using a center divider. currently my specs are, 2 12in Fi BL's 3/4in MDF Outside Measurements Height-15 Width-34 Depth-20 Center Divider- 18.5 x 13.5 Inner Port Dimensions Height-13.5 Width-2.5 Length-17.75 Those specs give 32Hz overall "if" i use them in Torres Tuning Calculator, now im a little upset cause i think im gonna be starting from scratch again being i added the center divider, if i split the width in half to make up for the center divider i get stuck with 51Hz If …

my friend gave me a box that had his 2 15" RF T2's in it. I am pretty sure it is 3.2 cubes after displacement and tuned to 38hz or so. Would it be okay to put some Fi BLs into this box or no? Tryin to save a little money and want good output. Or should I just throw 2 more T2's into that box and use it?

Wudup guys I need some help/advice once again about my box that I just picked up today..I made sure to include pictures so it'd be easier....well just look at it...a 15" BTL is going into it and i know it has the size. I punched the dimensions of the box into a box calculator and it's around 4cuft. But look at the ports..they look too small. Are they? I've never seen ports on a box for a BTL that look so small..look in the third picture. Also you can see that it's not an L shaped port...it just kind of ends..it's just straight as you can see in the third pic... Anyways it's supposed to be tuned to around 32hz but i can't figure out how i can make sure it is...any hel…

I have an 18'' Q and I saw that you recomend 6 to 10 cubic feet. What would be the difference in having a box that was 6 cubic feet rather than 10 cubic feet. I was going to tune to 28hz and I listen to country, rock, and rap about all equally. Will the smaller box change on how the sub performs and sounds? Also what's a good idea on how much port area to have. I always get told different answers. Some say 10 inches per cubic foot than some say 12, 15, 16, etc. Thanks

Would 2.3 at 33hz be good for a 15 bl.

My first sealed box for my 2 Q15's was 4.4ft^3. It sounded perfect. Now I have 4 Q15's sealed in 8.6ft^3 (after displacement). It is a little less then half the doulbed volume of the dual sub box. I assumed that my roll off would be nearly identical to my first box, or my tuning would be slightly higher, but it is actually opposite. It peaks at 35hz +/- but rolls off quickly above 40hz, as if the box is too big. Could it be possibe that the specs need to be adjusted do to box size or the amount of subs used? Maybe because it is all a single chamber? Because if this, I am considering doing a box that is about 10ft^3 with 4-5 4" round ports tuned to 34hz. That woul…

i have 18 cu to work with after displacements, and im wondering if that is enough air space for 4 bl 18s or do i need to step down do the bl 15s?

For the BL 15's it says 4 cubes max for each sub, so if I have 2 it would just be 8 cubes, no strings/formulas attatched? Also, the more cubes the better, correct? And lastly, I was thinking of tuning to about 33, anyone have some advice on this? Thanks

i made this box but i had to cut 2 inches of the top can anyone tell me what the tunning is

Huge thanks to JBLCAMRY here on the board for helping us out with sketchup and making the drawings for us. If they don't fit your vehicle..sorry. These are simply general boxes for the average install for a musical daily driving scenario. If you are looking to chase numbers you are on your own. http://www.soundsolutionsaudio.com/forum/forum/68-fi-technical/ Check it out! More to come later

..own one 12 in FI Q which i bought used, getting ready to purchase another. Wondering if there is a way to tell if the speaker i already own has the bp option so i can have matching subs... any ideas?

Is it possible to have some pics of the compression plug & axial cooling channels?

It feels like a good Friday to give away some free stuff...for the next 250 Q's that are ordered you get a FREE BP power upgrade! www.ficaraudio.com When will it end? No clue...jump on it while you can

I posted this question already in the technical category and only got an answer from JimJ ( thank you ) , and would appreciate more feedback so that i may place my order Asap , so i'm starting over in the general section hoping for more opinions , thank you . I'm going to order four 10 " Q's to be mounted sealed each connected to it's own Alpine PDX 1.1000 , ( all 4 were benched at 1200 RMS ) , my question is BP power or no BP power , i have seen posts where they were said to perform wonderfully under 1000 watts , and many more that stated they could take more , so i'm confused as to if i should BP them or nt please answer , thank you Dan

It feels like a good Thursday....BP Power for the Q's is free for a limited time!!!

Like the title says, I was wondering if there are pumping losses or air noise exiting from the cooling channels or the like thanks. Just to be clear, I'm only curious about bp power option only, let's just say the sub was inverted for reference.

Doing some counting...we set the limit at 250 for the Q's. Currently have 37 of the BP options left for FREE! Take advantage of it It won't last much longer!

I heard about this and was curious as to have it explained and confirmed if possible

Hey Scott, I emailed you, but read that other recone thread about not supposed to email you other then shipping, so I thought I'd post here. (And sorry I didn't read that sticky earlier) Anyway, In previous emails, we discussed reconing a 12" Adire Brahma MKIII, and I have the sub packed and ready to go. I just need a quote on the cost of shipping the sub back to me when it's done. I live in Honolulu, HI 96819. Thanks.
