Fi Technical

i have a home audio 15" powered sub that needs replaced was wondering if could drop a IB3 in it if it would be alright? Thanks Jesse

i bought a mt motor a few weeks ago and ups damaged it....the pole has shifted to one side........can you fix this? or is it a 53 pound paper weight?

What do I sacrifice by choosing this option? and can I run 2k to my BL's if I pick this and the other power handling options?

DAMNIT, well i heard a lilttle noise coming from my speaker today, hadnt played it in about a week, but anyway, i pulled it out the box to find that i have 2 holes in the spiders from tinsel leads, and numerous rips, guessing its from playing below tuning. i need to know how much a recone is scott, i dont know wether i will or just sell it, looking to get a new truck and there wont be room for a BTL 15, its loaded by the way, What to do??????/

My sub is less than a year old. Listening to it while driving on the highway one day at about 1/3 the volume and it just shut off. I thought it was the amp or a bad connection somewhere. How do I get this fixed? Is it covered under warranty? I have an Fi Q 12

I have a 2001 PT Cruiser with a alpine 9887 hu: I used to have to pussy type s subs in the hatch and just didnt cut it at all. Saw the FI Q and fell in love.. So here is my questions if a get the Q 15 with BP and a Bxi1206D amp and then a PDX100.4 what do i need to do to so i have adequete electric power to have it all run???and if yall have any product suggestions please feel free...but i am only 17 and just graduated high school so i aint the richest kid around.

Guys finally going to start building an enclosure for my Q 15. My plan is to do something like this: http://i161.photobucket.com/albums/t203/wy...enclosure-1.jpg I am aiming for 3.5 cu. ft net after port displacement with port tuning of 30-33hz (does that makes much difference musically??). My question is: 1. What is the recommended port are for the Q15? I want to make the port as big as possible for more air to move out of the port. 2. Has anyone ever modelled the Q15 in WinISD as everytime I tried to key in the value either I will get some errors or different t/s value. I dont know whether my box will yield linear response. 3. Has anyone (expecially Scott or Nick) can …

Waiting till thursday to order teh new 12" Q but I want to get started on the box... I've got room for a 29.5x19x8.75 deep box... (this is going in the back of a 350z) This puts it at about 2.05 sq ft after the driver displacement. I was going to go sealed, but have changed to ported... I need to figure out the length of the ROUND port to use... I saw a post on the 350z forum where a guy used two 3" ports at about 32Hz "needed 34" total of 3" port to be tuned @32Hz" Can someone confirm, using your awesome math skills, that 34 inches total of 3" port is correct? I'll need to split the ports into two ports... I'm aiming for this look... FI Q12 in the Z... - MY350Z.COM For…

I've had a Fi Q 12" for several years now... I think I got it in 2008, maybe 2009, but it was before they changed some of the options available. At the time there weren't many options and I went with the most basic setup available. Basically, I've had to reduce my trunk space consumption by moving my audio gear (wife and I had a baby in September!). Last summer I managed to move my Kicker ZX200.2 amp which is powering my front speakers (Eclipse SC6500 6.5" components with passive crossovers) and attach it to an accessible metal panel in my trunk, and I actually completely removed my Fi Q 12" in a 1.25cuft (gross, not net) box, and my Kicker ZX750.1 amp that Kicker rated…

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?

right now i have a fi ssd on an aq1200d but i want to get a btl and maybe score the free cooling option before july 29 but i haven't been able to sell my aq1200d so i'm thinking bout keeping it and just buying another one and strapping them together but i will only be able to run it at 2 ohms so what would be better 2 aq1200d's @ 2 ohms or 1 aq2200 @ 1 ohm ? and how would i wire the 2 aq1200d's? this is my first post so sorry if it's messed up at all lol

hello guys I have two Q15's in a dual chambered slot port box tuned to 27hz @ 8cuft. My question is will it be better to build another enclosure where the drivers share the same chamber? And should I double baffle it? Also, what about bracing? How do I go about doing it? I tuned low because I want the ground pounding bass that you get from the lows as I don't really play anything above 45hz. Thanks.

look at the cooling channel around the one o'clock position, it isnt lined up but all the rest are! is this normal? if not any performance issues from this?? thanks

hey i got some cliff designs cd120c and im looking for recones need to handle about 1400+ rms they will be on a rd 1750 for now but im upgrading to a sundown 3000d. got anything. pics thanks

Well my mojos are starting to suck...blew a coil actually. And now its time to upgrade to BTLs I'm stuck between 2 15s or 2 18s Here is the scenario: The ports will be outside the box. I am going to use these ports... Deal Breaker for 15s: the only practical option is to use 1 of those ports for 8 cubes Fi recommends 12 - 16 square inches of port per cube 8cuft x 12 = 96 8cuft x 16 = 144 So about 96-144 sq inches recommended. that port is only 70 sq in. Would that be a problem? Deal Breaker for 18s: The only problem for the 18s (using 2 of these ports) is that the box would simply be too long to conventionally mount the ports outside the box... So to still be able to …

Hello, I plan to build a box for my Q18's (bp option). The box will be 12ft^3 tuned to 28hz w/4 4" aero ports eash measuring 11.5" long. Each 18 will be receiving 1600w. Please tell me if my specs are ok or not. Thank you, Larry

hey pm me or shoot me an email at [email protected]

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?

my max dimensions are W:40: H: 14 or so D: 20 freq wanted. : 32. Daily driver. could someone help me our, or is my height screwing me over?

I am looking at getting a 10" Q. Would a Crunch GP2250 be a good choice of amp if I got the dual 2 ohm? I would bridge the amp and wire the sub at 4ohm. If I'm not mistaken then that would be 1000w rms, right?

So after selling my Avalanche, i put my 2 13kv.2's back in my car. This is when i realize how amazingly low the avalanche gets. I am almost set on purchasing a 15" BL to replace the avalanche, but i just want to be sure that i will not be dissapointed with the low frequencies. I know it will get loud, but hell my 13kv's matched my avalanche at certain frequencies too. (BL will be on 1200 watts in 3.5 @30hz if it matters much) Anyone with experience with an avalanche as well as a BL (or other Fi sub, i assume they are a bit similar) please give me some input. I want to be absolutely positive that the BL will be $300 well spent. thanks.

I plan on building the enclosure per Fi's specs of 1.5 ft @33hz. The dimensions I have come up with is 14.5" x 14.5" x 18" using3/4" MDF this gives me 1.4937ft after subtracting the woofer and material displacement. I can add to the 14.5" sections of the enclosure if need be to account for port displacement. I'm not familiar with how to calculate port displacement though so I'll need some help on that as well. I planned on mounting the sub on the 14.5" X 18" side and would also prefer to have the port on that side as well. I just want to make sure that I get this right. I'm looking for maximum SQ but still want to have good output. It will be powered by 550w/rms in a PT …

Hello all, First post here, so be kind to an old-schooler... Looking to do a bed box in my Chev 1500 step side. Max dimensions I've got are: Width = 48 Height = 18 Depth = variable I'd like to go with 2 BTL 12's, dual 1ohm. Both subs will be powered by a RF T2500. Wondering if one of you fine gentleman would point me in the right direction with: Net Vb for common chamber enclosure... 2.65 cu.ft. per sub? Optimum vent dimensions based on a 16.5" vent height? Hopefully I provided enough info... I certainly don't expect a full design, maybe just some guidance. Thanks guys, C

I was wondering is doesnt have a size recommended for the 15 ssd in a sealed box? Is there a reaosn for this? would they sound good in a sealed box? If anyone is running them in a sealed box how many cubic feet do u have them in? I cant run them in a ported box because the box would be to big to fit in my civic, any help would be appreciated, thanks

Ok, I Have the Pioneer AVH-P5000 HU, an AQ-2200 amp, and 2 Fi Q 15s that are in a 5.5 cu.ft ported enclosure after all displacement that is tuned to 35 Hz. The HU has a RAC output of 4 Volts so i match that voltage as close as possible (3.9V). I tuned my enclosure to 35Hz so my Subsonic level is set to 30Hz. I know that the gain is the most important setting to any amp, followed by the Subsonic filter if you have a ported enclosure. Now am trying to find out how to set my Bass Boost and Low Pass Filter. I looked through the forum found info on the Gain and Subsonic filter but couldnt find anything on the BB or LPF. Are they just set by ear or do they have parameters. Can …
