Fi Technical

hi all i was wondering if anyone new the le:, z:, and pe: of a fi Q 18 because i need them to design my box on winisd and fi doesnt have them listed. thanks

Ok, I have an older BTL18 that was originally a D1 (written on the pole) and its in need of a recone. The owner got ahold of a D2 BTL18 kit, and I got the basket cleaned up and ready. It an older non-woven tinsel kit. But, I have it a snag...the D2 coils OD is noticeably larger than the D1. I have the kit shimmed and in the gap, but is this kit going to work??? Or will the coil hit the top plate when playing? Its a tight fit, but does have some space. Anyone make the D1 to D2 switch? Please reply soon...the owner is in need of a sub.

I notice that on the Fi website that u have options that u can add to your sub before purchase. What does these options mean? Flatwind coil? Copper Coil? and BP Power? Can i purchase this sub without this stuff. If i dont then how will the sub perform in daily uses? Oh yea, is there a big difference in hard hitting bass with the SSD 15 and the Q 15? Thanks.

Can somebody post them up? Trying to see if they'll work on my rear deck using the 19.1 cubic foot Cadillac Deville trunk...

I have the ability to do a drop in head to head test w/ TermLab results between a Havoc and a Q 15 ported tomorrow. Anyone interested? And any other test you guys want? I have a TermLab, a Havoc 15, and a Q 15 so all is good to compare if there is interest!

does anyone know a phone number or something to contact fi about a question? ive tried emailing and it didn't work, they ignored me. i ordered a fi q 18" about a month and half ago and i noticed it had a black basket instead of gray, then i ordered another one a couple weeks ago and it had the gray basket and many differences. and just over a week of having the newest one, there is a popping noise coming from the sub as if its starting to go bad already. any comments just let me know....thanks.

Right now i currently have 2 boxes around 5.4 cubes per box @ 34 hz. I know i really could get the BL's to slam the lows alot louder if i got around 7 cubes per sub. SO with that being said im going to make 1 ported box*walled* and tryn get my max dimensions. I was going to get crazy and fiberglass all the nukes and cranny's but im really not the best with just winging it and figuring out port lengths and cubes when its not a regular rectangle. On to my question... Do you find the Sq. inches for port area before or after all the displacements. EX. I have 15 cubes to work with total 45x34.5x20 external dimensions for 2 18" BL's Do i multiply 16(rule of thumb) sq inches x 1…

Will somebody please explain to me where the length of the port is. In order for my box to be tuned to 32Hz it has to be 22.5" long but which piece of the box is it? is it C or B?

In order to get a 1 ohm load out of the 2OHM DVC, I wire the two negative terminals together with speaker wire coming out of one of them, and both the positive terminals with speaker wire coming out of the same set that the negative came out of right?

im planning on making my own box for my btl. but im not really sure on the port at all. so here is my question im planning on making a box with about 4.5 ft3 of air 35.25L x 18W x 17H how big should i make the port if i want to tune it to 32hz? like the outside length and width, and the internal length of the port thanks if you have any suggestions ill gladly take them this might of been posted before but the search hasn't worked for a couple days now

I have a 2003 Chevrolet Tahoe and I am going to put a Fi BL 18" in it. It will be powered with a Rockford Fosgate T10001bd amp and a Kinetik battery. Just ordered it yesterday I have a general idea of the specs on my box in order to fit the 5-10 cubic feet. It will be about 9 cubes by the time everything is displaced. The only problem since I am new to car audio and this is my first system is what are the dimensions of the port? The box will be W 45" x H 20" x D 20" with 3/4" MDF. I want to tune the box to 32Hz. Any help will be appreciated. -Kasey

Alright right now i have a FI Q12" running 1000 RMS@ 1 ohm (with knob at 10% power) thing hits harder then hell right now, in the past iv always used sealed boxes and when i got this one i got a ported to see what the hype was about I want to get a sealed again but if i do will i lose those super deep lowes or is it the sub itself that makes them. (basicly i want to know will i get the deep lowes with a sealed)

Im thinking about trying to put 4 BL 15s in a 2000 maxima, Do you guys think its possible to fit them in the trunk and only the trunk?

Im getting 1 18'' fi.btl fully loaded and my enclosure is going to be 6.3 cuft. (After all displacements) 3/4mdf tuned to 34hz. But as far as the port can you please tell me how long,tall,wide,etc. it should be for best hairtricks,loud bass at high notes,and the best low bass I can get (Since being tuned to 34hz.) without port noise. One more thing as far as the enclosure should I have the top and bottom of the enclosure double baffled or triple baffled or the whole enclosure double or triple baffled or what? Please help as much as you can I really appreciate it!!! Thanks guys

1- when are there going to be stickers 2-when are you going to make a badass hat?

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

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?

room wise im stripping everything out of the back of my car and starting again.. the box in there is 3.5CUft with displacment to give you an idea on how big it is, i need some ideas of port and sub postioning which way to face them, where to put them? and general box design also some advice on the actual sub will be using for : Daily use 2000RMS @30Hz so what options would be best for the sub? Vw lupo thank you

I placed an order for 1 FI BL 15 dual 1 instead or 2 am i ok

Box is for a FI BL 12 in a Dodge Stratus. I went with a 28Hz tuning for more SQ over SPL. Please share your thoughts Port Type: 4" Flared Port Port Tuning: 28 Hz Number of Ports: 1 Net Internal Volume: 2.5 cubic feet Port Volume: 0.0066 cubic feet Subwoofer Displacement: 0.1500 cubic feet per subwoofer Total Internal Volume: 2.6566 cubic feet Number of Terminal Cups: 1 per subwoofer Front Baffle: Single-Layer Front Baffle - 3/4" Thick Box Dimensions: 22.625" (w) x 20.125" (d) x 13.75" (h)

I plan on ordering a BL12 and am not sure on what amp to get. I was looking at the Alpine PDX 1.1000 for one BL12. Should that do that job or is it not enough watts?

I have a 2007 4 door silverado and want to know if there is a way to build a box for a BL 12 to fit under my back seats. If so, any ideas?
