Fi Technical

I just down sized with my new vehicle so im thinking of running 2 15" Fi Q's sealed to help conserve trunk space. I want to keep using my T2500 but my question is will this be too much power to run these subs sealed? i plan on using an enclosure that is approximately 3^3ft per chamber. The car is a 2006 Impala SS. Any help would be much appriciated. Thanx.

i am about to buy the aq2200d amp, and i am still wondering what subs i should get... 2 18in. bl's or 2 18in. q's. i know the q is for sq mainly and the bl is more for spl. i want what ever one will perform better on that amp. thanks

Hows this sound to you guys. (2)15 Bls Box: 17x39x22 = 6.54cubes (after displacement) Will (2)4in flared ports be enough port area or not enough? suggestions please

My new box will be 4 cubes at 30hz, with sub up and port facing the tailgate in my blazer. (5 inchs port to tailgate) My running it with a sae-1200d So my question is, is this box too large?

Hi all.I just placed my order for two SSD 18's.I can't wait to get them but in the mean time I was wondering how much power can they handle? I have a Autotek Street Machine 1500 watt amp that I was planning on using with them put I was curious if they could handle it.I did not get the BP power or flatwind coil when I placed my order.I got dual 1ohm instead of dual 2 ohm voice coils so im planing on running the subs at 1ohm.Any advice or help would be greatly appreicated.Let me know if any more info is needed and ill post it up.Thanks

I got two 15 inch BLs and I would just like to know how to tune the enclosure port to 33 hz? Is there some sort of program that could show me how?

How do these box plans look. I plan on using them for my 15 inch SSD. It is going in a trunk of a 94 Honda Accord http://flickr.com/photos/8063442@N08/sets/72157605256765339/

I looked at the voice coil on one and there were markings. What does FC FW mean? Plus how will I know if it has the cooling option I ordered?

How does this design look? aprox 4cubic ft

Ok I have a 07 Saturn ion I'm going to put in a q18 in the trunk. The box from the cut sheet for a ported box won't fit.... My trunk is 14.7 cf so getting a 7 cf box in there can happen I'm just clueless on how to go about it. My opening is 19x40 Ball parking that. of course there is the angle too... Any tips or ticks to get this built and in there would be very helpful. Also I hope I posted this in the correct spot.. Also I feel havering the sub firing tends the trunk lid would be my best bet

Hi, i'm buying 2 Fi BTL 18's and was wondering how i could build a ported box. i've never built a box before so i need a lot of help. If you could tell me what i need to buy and how to do pretty much everything to build this box it would be great. Thanks

how many decibals are you you guys hitting with your Fi BTL 18"

Hey I'm hoping to have a Sonic FX Q 12" very soon (assuming DHL can find it ) I was wondering if you guys could recone it in the worst cast scenario were it gets blown??? It is very similar (practically the same thing) to Incriminator Audio's Death Penalty series, (in case you don't recognize the sub). I was just wondering what soft parts you would use in reconing it??? BTL, BL, Q ???? If you need more info on the sub let me know and I'll try and find it for ya. Thanks! Jon

I read the recommendations for each speaker, but still have a few questions. First, I'm going to be ordering a dual 2ohm fully loaded 15BTL, Its going to be for daily with roughly 2500rms to it. My question is, is going fully loaded the right choice? Or will some of the options hurt the power handling instead of help it? For instance the universal option because of the gap size? thanks for the help

I am pretty sure I have neither the room or the amp for 2 of the Qs but I am getting 2 of em for $260 If I did want to change amps and run 2 Q12s, how much air space would I need to do them justice in a sealed enclosure? I have started to consider using both after a day to think about it. Initially I was only going to use 1. So, I guess I have 3 questions enclosure space for 2 sealed enclosure space for 1 ported enclosure space for 1 sealed Thanks for any and all help Jman Oh, the car is my 2001 Trans Am, I kinda want to use the space available on top of the gas tank in the rear hatch and get my ttop space back. If not familiar with the hatch in a 4th gen f-body, chec…

It is 6.5 cufeet internally tuned to 30hz with 111 inches of port area. What is your guys thoughts on it? to much/to little port area? not enough room inside the box? just post what you think on it.

are there any differences in the 08 and the 09 BL models? i would love to add another 15 but concerned about putting two different subs in the same box, are they any different to the point where you couldnt put them together in the same box?

Hey, So I got a 15" Q D2 right now and just sold my crappy amp. I'm planning to get either the SAZ 1000D or a SAE 1200D. Which would be better if eventually I will get another 15" Q D2?

I have 2 D2 18inch Btl's and 2 SAZ 3000ds I need to know how to wire the subs down 2 ohm, because i'm strapping the amps together.

I should be getting my new ssd 12 soon and a alpine amp that pushes 1krms at 2 ohms. I was wondering if the sub will handle 1k without any problems. I usually dont have my radio blasting 24/7 (but like to show off for a song or two) and most of the time im listening to rock/metal. It will be in a sealed box and i got no options on it but Hqts. So the real question is can i run the amp all the way up (gains set correctly) or should i run about 3/4 level. Thanks for the help.

i have been working on my box design this would work real good with my trunk space. http://www.soundsolutionsaudio.com/home/bo...ideboxcalc.html is the box good to build or is there way too much port, fi recommends 12-16 per cubic foot of enclosure area? crap it only posts the default box... my box is the following: box width 35, box height 17, box top depth 19, box bottom depth 19, box thickness .75, square port width 4, square port length 2-16

Hi, is it possible to convert a btl from 15 inch to 12? And what would be the price? More than a new 12 Q? I'm from germany so it's not possible to send this thing in.... Thanks Patrick

I'm looking at a BTL15, because I've heard good things. But until I get enough, I would probably be running 1 Sundown 1500d on the BTL15. If I got it optioned out, would it be able to handle a pair of strapped 1500d's? How much can a optioned daily driver BTL handle?

Would there be any noticeable difference between making one huge box or leaving both of them in separate boxes, advantages? disadvantages?

Anyone have the T/S params for a fi x 10"? Team FatStig
