Fi Technical

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 have a mazda ext cab pickup and have about 12cu feet to work with. I really want the FI Q18's. I have never owned a pair of 18's and that's what i want. I want to kind of do what Steve Meade did in his honda and build the enclosure inside of the truck. If i can't do that this is the space i have to work with 30in high x 49in wide x 14in deep. If i built inside i think it would be a little bigger. I was wondering if I can't fit 2 of the Q's, should I just use 1 of the Bl's?

Hello I have a jeep srt8 with two rockford fosgate 1500.1 bcd's and four rockford p3 15s in a custom box tuned to 35 hertz. I want louder now. I've been hearing alot about the fi subs. I wanna keep my amps but get four fighteens that will do great with my amps. Both amps comined will do 3900 watts rms. I've been looming at the fi bl line. They are rated at 1000 watts rms 2000 peak. So if I had four Of them they would be 4000 watts rms , I would only be shorting them 100 watts. My question is can these amps slam the bl pretty hard and can I use my same enclosures I have now with 12 cubic ft and , 6.1 per chamber for two subs on each side and tuned to 35 hz. Basically each…

I don't compete and would like a SQ/LOUD SOUND QUALITY setup and am having the hardest time designing a box to use. Obviously Fi recommends a sealed enclosure and that's what I was going to do originally until I started playing around in WinISD. Now I'm completely unsure so I figured I'd ask you guys. How do you guys think a 12" Fi Q would sound in a 2.3 cu ft enclosure tuned to 24-25hz as opposed to a 1.3 cu ft sealed enclosure? I can't upload the WinISD output on my current connection but I will after midnight when I get home.

i want to know if 1 fi x 10" is good on a 200 watt amplifier. and what dbs could u get out of one

Has the title states, how do I get a 1 ohm load with 2 btls? My first previous subs where dual4 so I wired them in parallel. Do I need dual1 ohm? If so how do I wire them? Thanks.

Hi, I'm about to order an 18" btl I just got done going through the options i'm bit confused as to what ohm to get I want to run it at 1ohm the amp ill be using is a HCCA-D5000 monoblock my qustion is should I get a duel 2ohm and run it in parallel or what? how would I wire the sub if it was duel 1ohm, split the pos and neg in the box and hook up all the turmanals?

Can someone give me the screw hole diameter of the 15" Fi BL? I saw the outer diameter was 15.625" but did not see a screw hole diameter. I am working with limited height and don't want the screws to be lined up on one of the boxes wall. Hoping I can save around a 0.5" inch on the height just having the outer surround overlay on the outer 3/4" edge of the box. Thank you for any help! I would measure it myself but I am ordering the woofer in the next few days and want to start the build now.

Besides the voice coil, what are the differences between MT and BTL softparts?

Hey guys, I have Manny from http://www.trexcaraudio.com/ building my box for 2 18" btls..and I was just wondering if this sounds correct, his calculations for the box: 19" high 40" across 37" deep 95 sq ins port is 13" long (tuned @ 32 hz) and is 11.79 cubes thnks, Freddy

hey guys, i would like to know what you think of this box, im a some what noob/mid level at box building SUB- ssd12 basic with maybe a flatwire option AMP- rocksford t500.1bdcd, the birthsheet on this amp say it does 810watts at 1 ohm, which is what i will be running it at. here is the box http://s1244.photobucket.com/albums/gg580/ott9311/?action=view&current=a1_zpsf9dcb1d5.jpg please give me any input u would have, i listen to alot of rap/hip hop so im tuning for 33hz i know im prob under powering the sub, but i thought in a ported box you could under power it by a LITTLE bit. based on my above state facts, should i make the box any smaller or bigger? more or less po…

i have a 15' Q. want a box that will get really loud. recamended size is 2.6- 4 cu ft. @ 28-33Hz. with 12- 16 sq. in. of port per cu ft. would a larger port be better than a smaller one?? i was thinking of doing 4 cu ft. @ 35 Hz. with a 6" x 10.5" port. how long would i need to make the port to tune at 35Hz??

I'm going to run 2-18'' BTL's each in there own box with 2500 watts to each sub. I would like to know if 6 cubes each would be good for the power that i'm running or should the box be bigger to reach full xmax? And do you have to add the ports size to the size of the box or not? I know you add the sub displacement to the box so do you add the ports to??? Want to run 2-6'' Precision Ports pre sub tuned @32hz. Does this sound like it would work? Want LOUD DEEEEEEEEEP BASS. And what is the disp. of a fully load BTL? Any help would be great.

im looking for a ported box for the trunk of a 95 caddy, 14"H 14"D 38"W is the max for the box. it's for a 12" ssd how long/big should i make the port to tune it around 33Hz's it also going to be powered by an alpine 650 watt amp.

How much do they take up as a far as displacement goes..

does an one know the displacement of a fully loaded BTL the web site say .26cuft but thats not with the 3rd slug, just tring to get as close as i can so that way my port will be as tuned as possible, or is .26cuft close enough

I scored 2 15"q's of ebay for 405$ So im in the process of designing a new box for them. My box total after speaker and bracing displacement is 11.488cuft. So i need about 137-183 inches of port area. I was thinking a 9inx20in port 25.84 inches long for 30hz. That would leave me 8.798cuft after all displacement with 180 inches of port area. Does this sound good? If not what would you reccomend?

i need 2 mt recone kits for my 15's i will also need the glue and i would like to have them dual 2 ohm plus i would like to have the fi dust cone can any one help me out with this i need to order these asap no response on web site

I ran 2 bl 18's off 2 sundown 1500d's for little over 2 years with no problems at all. Those bl's had cooling, flatwind, daily options. Now they offer to have a 4" coil for extra $50. This time I will be running either an aq or sundown 3500 on 2 18's. With the 3500d should I go ahead and get the 4" coil, Im pretty sure the 3" would be fine since I ran the others with no problems that long. thanks for suggestions

im redoing my room and i want the fi revolution picture you see when you first go to the website in high resolution cuz my teacher is gonna make me a laminated banner for my room and i cant seem to find a high quality picture or the picture anywhere for that matter i looked everywhere and cant find it and now im asking around is there a way i can get the picture emailed to me or someone know a website i can get the picture?

I've seen that Fi is using woven leads at least on some products, is the Q on of these? Also is this change going to make it over to the AA Havoc any time soon?

I've tried searching for this, but to no avail, so here's my question: I am planning to mount an IB315 to the rear deck shelf in my car, but not in the usual drop-in fashion where you screw it in from the top. It will be mounted with the front of the woofer touching the wood baffle and screwed in from behind the woofer. (Maybe there's a term for this, but it eludes me.) What diameter should the cutout be? The specs say 14.125" for the cut inner diameter, but I assume this is when mounting it normally. I am mounting it this way to leave room for the excursion so that the woofer won't touch the speaker grille cloth. I am trying to make as many modifications to my car…

I got a baffel cut for my 12" box so I could convert it to accept my BL 10", I have a box uilt to spec for the BL only its for 2 BL's. I have not got around to ordering the 2nd (money) so I had to put it in something else until I get the second. My dual box is common chamber, so I cant run it that way without the other sub. So, I put the BL in the 2.15 cuft box powered by my 9.1, 1200 rms, its very loud and low, only, I know its not good for the sub to be in a box thats too big. I hear it will make the sub super efficient (spelling) , I am thinking to add some MDF to the box to shrink it down or run the sub at 4 ohms (450 rms) until I can get the 2nd one for the dual inst…

Hi All, So I've had my two 12" SSDs in a sealed box, 1 cu ft chamber for each sub, for almost a year now hooked up to a Sundown 1500D. It seems like I don't get the lows like I would expect and I'd like it to be a little louder. Do you think it would help to build a ported box for these guys to see if I can squeak anything else out of them, or is it possible that these subs just don't fit my wants? Thanks.

Hello Guys. I guess I could introduce my self before i start asking crazy questions..My name is David, I am a Firefighter, I live in Mississippi...I ordered one of the Fi 15 BL with the cooling option, Flatwind option and Universal setup..Daily driver...I am going to be powering with a Xt4000d Us Amps Amp. I have a Honda Civic and I will be using a ported box in the trunk..I have designed a box and was wondering if you guys that see these designs everyday think this one will do me justice...I used some measurements I took of my trunk and how I would like the box to sit...I will 45 all the corners in the box and build it as close to this as possible...Please look and tel…
