Fi Technical

Scott we talked about you reconing a DD 2500 motor which has a 2.5" coil. Well i was woundering if you have any coils that will fit an Atomic AP/SPL gap? If so im going to send you an email with some more info. Just wanted to check with you before i picked up these other two motors. Corey

Hello all. I have just found out about Fi yesterday. Seems like a solid product. Everywhere I read everyone has positive things to say about them. I am in the market for new audio toys in my truck. Stumbled on this website and thought id ask some of you gurus about some suggestions. Some info for you. I have a 05' Single Cab Dodge Ram 1500. I have taken down some measurements of what the enclosure "could" be up to. I would like if possible a slight wedge box so I can still lean my passenger seat back a little. This is what I came up with. Length of box from side to side = 38" Height of box = 18" Bottom width = 11" Top width = 8" Ive done this calulation on Fosgates box …

Wondering on box size for strict SPL setup. Would it be best to use the 3 or 5 cubic foot box or some other size. Tuning will be 54 hz. Not sure on port size yet but thinking 150" per sub if I use the 5 cubic foot size and 90 on the 3 cubic foot size. Will be running 2 Sundown Audio SAZ-3000D to each sub off a 16 volt system. Willing to listen to suggestions.

Here is the box i am gonna build to wall my Civic up..Let me know how it should match up with 2 Fully loaded daily 15 BL's. http://www.subwoofertools.com/forum/ported...mp;Fs=&CE=0

Adrie Brahma MK I Motor can it be reconed from fi? thanks

Hey all, bought a 15" Q last night to mess around with and have some questions. Recommended enclosure is 2.8 to 4 cubes and tuning anywhere from 28 to 33. I need to figure out where in that range I should build. I listen to mostly metal, rock, blues/folk and on the rare occasion I'll crank some old school hip hop. I know kick drum is front stage and I will get flamed for this but I still like cutting my subs at 80 to get some impact for kicks out of them. I have a Kicker sx1250.1 that will be going on the Q so it will be just a bit over the rated limit of the woofer. It will be going in the back of my 07 extended cab F150. I toyed with the idea of going sealed but I …

I was wondering if you could possibly give me plans for a ported box for 1 fully loaded BTL 12" dual 1ohm sub. Powered by an Earthquake PHD10000d 3000 watt amp. My trunk dimensions are 36"L x 36"W x 17"H. here is the plans I got off a website. How does this look?

I need some help with the dimensions of my slot port before I go ahead and make a disaster. I have a 15" SSD in a 3.8 cuft box. I'd like to tune it to 33Hz as per Fi's recommendation Using one of those online calculators I got the following dimensions 3"H x 6"W x 5.22 L Does that look right? How would that be affected if I wanted to make 2 ports? Any help would be appreciated

Ive been looking for a "special" basket for my 05 15 XXX woofers for a while and i was wondering if FI would be able to help me out? I know all you guys use are the 12 spoke but i was wondering if you had anything different could make somethign different or knew where i could get something different? (other then the 12 spoke or the 6 spoke DD design) Im honestly in love with the last generation of the fosgate punch HX2 baskets but since its been some time since they sold that woofer i havent been able to pick any up.... So got anything for me scott?

someone on another forum posted about more thiele parameters then wats on the site says he wants to know everything plus motor strenth can yu guys help out

sorry to be busting balls... please search ur email for "Recones & OEM work" from [email protected] or [email protected] thanx Scott

2004 Monte Carlo a pair of 18" fully loaded BTL's a pair of Power Acoustik A3000D amps one lonely termlab 500 pounds of wall... 153.6 @42 hz windshield 152.5 @38 hz MECA reality stand 151.8 @30 hz winshield ...and just for Meade... 150.6 @27 hz all in all these subs are very impressive and tough. the monte carlo lacked a lot of the needed airspace to make this setup do the 155 i was projecting but a little added wattage will fix that issue (BTL's like power and dont be afraid to give it to them). innitially there was some metering issues getting the car to go over a 150 which is the main topic of my post. 40…

ok here it goes... and you know i have 2 15 fully loaded bl's dual 1's.... i have the + from one coil to the - on the other coil... on both subs... then + from one sub to the + on the other sub... then the same for the -... from there to the amp...... i should be at 1 ohms correct? or did i mess up should i have gotten dual 2's heres why i ask... im sitting some where around .8 ohms.... not 1. not 1.3.. but .8 thats with the resestance of my ohm, meter the resestance of my meter alone is .1...... so by my messed up math that should put me at 1.1... but hey maybe im wrong...... the reason i am so scared... ok here goes i shopped for months for subs and an amp.....…

How u doing FI, im from miami fl and i have a single cab dodge ram 1500 with 3 15" kicker cvx subwoofer in a sealed box. All powerd by 3 1100 MONOBLOCK MEMPHIS amplifiers. I have 2 kinetic batterys and a 250 amp alternator. I hit around 152.4 db. now i know that your bl 15 will fit in the box, but i only have 1.8 cubes per speaker. what do u suggest? Maybe getting the Q that also handles 1000 watts rms? basically what speaker will give me the most db's with the set up i have now? here is a pic of my set up. Thanks and i look foward to joining team FI

Hey guys, as the topic says I have a problem with a SSD 12... the spider feels very weak in a spot like there is a crack under the top one. So my question is will it be fine to run like that? (i don't know how long its been that way but it worked fine till the day I took it out) or do I need a recone so it doesn't get any worse? Thanks

I have a pair of 10" BL's. I'm running these with an MA Audio HK4000D, I've been running it at 2 ohms so they'd get about 1900 watts each. I'm planning to drop the ohm load to .5 and send them more power, at least 2500 watts each. What would the recommended enclosure size be for this increased power? I'll figure out the ports and such after but I want to know what size enclosure would be right for that amount of power.

Does the sub come with aluminum or copper coils? sorry if theres a thread about this but i looked on the site and couldnt find a difinitive answer on this. Also what exactly does the BP power option do, does it effect the sound of the sub whatsoever or is it something just to help with thermal capabilities of the driver? thanks in advance.

I broke one of the terminals on my BL 10" yesterday when I was pulling it out of its box. The tinsels are fine and the sub is still working perfectly. But the terminal is moving up and down! I am thinking it is going to start vibrating once it gets moving! I dont know how Fi had it secured, I am thinking it was glued down, if so, what kind of glue should I use to reglue it?

Whats the sealed volume recommended for a 18" ssd?

so i hear ia is coming out with a 21" subwoofer. should i expect fi to come out with just as big or bigger in the near future? Damon

I just bought a 12" Brahma MKII, its working but has had the tinsels resoldered after they broke. I was going to attempt to repair the tinsel leads and run with it like that, but, the guy I bought it from originaly said it was a 10" , now he says its a 12" , so I want to go ahead and recone it down to a 10". So, I want to go ahead and place an order for a 10" recone kit with 10" basket and gasket shipped to 26851. Just wanted to post this here before I send any emails.

YESSSSSSSSSSSSSSSSSSSSSSSSSSSS enclosure 3.7cu ft net volume after port and displacement tuned to 33hz My BTL full loaded off the Digital Designs Z1 is a wonderfull combo...... but very disapointed to have issues with this amp...... huge power but poooooooor quality

Will a 18" BTL handle 2 Memphis 4kw for Street Beat or burps. Also when building for SPL only is it better to use a small or large box. Can you also let me know what a recone costs for a BTL a 15" & an 18".

assuming both are in 8^3 ft @ 32 hz with 3kw to split between them @ 2 ohms with equal installs. which ones would be louder? my main concern is, do these subwoofers basically take power the same way and just 1 gears it more towards an SQ aspect and the other a SPL aspect. or is basically just the power applied that will determine which is louder? i mean both are rated @ 1kw and the only thing that seperates them are the power options that apply to the thermal side of power handling. but mechanically, as far as power handling goes, are they the same? same stiffness spiders etc? i have been told by one guy that his 2 15" q's were louder off 1.2kw of power than his bl 15's t…

This is the graph i got from WinISD volume is 5.4 port is 4* 8 * 11 (dont know if thats the right port size or not. I would like it tuned around 32Hz) http://i235.photobucket.com/albums/ee29/mld42/FiBL.jpg This is a very rough sketch of the box to show where the ports could go. The sub with be mounted inverted for more box volume. I have 2 12's now in a sealed box, but would like something louder, and I have a BL 18 dual 2 that im not using so I am trying to fit it in my truck. http://i235.photobucket.com/albums/ee29/mld42/Blbox.jpg And is there any way to extend the port out of the box rather than porting the inside. I havnt seen this done so I dont know if it wil…
