Fi Technical

I was just wondering, if when adding a port to your box do I minus the width of port and then I'll have my true area of space the actual woofers will be in?

I am looking to build an SPL box for two 15" Fi SSDs with copper coils... I am just going to switch out of my daily box to this box when I go to competitions... What size box, and tuning would be best? I have a '95 4-door Blazer it will be going in.. I was thinking something along the lines of 6ft^3 tuned to 45hz..

this is the size of box i want to build: 16tall x 40wide x 28deep, there is an internal volume amount of 8.11 cu ft. after you account for the entire top being double baffled... subs up, port back (in the middle). i came up with a port, 13.75tall x 8wide x 23.5deep for a tuning of 32hz using this program: http://www.carstereo.com/help/Articles.cfm?id=31 i used the "Calculate Your Vent Length" section to come up with that port. it asks what tuning frequency you desire but there is not a place to enter how many or what size drivers you are using. is that port good for four 12"s?

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.

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'm trying to decide on a sub for my car, and design an enclosure for it. I listen to a lot of drum and bass, so due to the wide range of frequencies, I've already decided to go with a sealed enclosure, and I have a Hifonics BXi 1606D to power the sub. My original plan was to go with a 10" Q, as I figured it would be more than loud enough, even sealed. The issue I've run into, however, is that I want to mount the amp on top of the box, to keep things more compact (take up less trunk space), and to make the box and amp easily removable for autocrosses. The problem I'm having is that once I make the top of the box large enough to hold the amp (~11.25 x 14.5), and make the b…

last wee end i was playing around with my system and i was play with a cd that went 1 to 100 cycles and sweep. i thnk that i might of found my sweet spot for my explorer around 46 to 48 hz. i was look at get 2 fi sdd 18 and i as wondering would 46hz to48 hz be to high to tune a box to?

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?

New to Fi and just picked up a 18" btl. Need some suggestions on box size and tuning. I have about 10 cubes gross before driver and port. Looking to do a sub up, port back, tuned to maybe 35hz with 4k of power. A few have said that these have tremendous bottom end so I'd like to tune appropriately.

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

Could somebody tell me what the diameter of the magnet is on the 12" BTL. And, what is the mounting depth of the same sub is. And one more thing, if I build a box that is 5" at the top, 11" at the bottom, 20" tall, and 40" wide, will that be enough room to fit a 12" BTL with just cooling(will it be deep enough)?

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

I'm lookin to run a pair of Q 10s eventually but I'm just wondering if anyone has experience using them in a smallish sized ported enclosure? .7 cubic feet to be exact, 10 sq inches of ported, tuned to 30hz...per driver of course. Thanks in advance.

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"

I'm currently trying to design an enclosure for 3 Bl 10's i've got 1.85cu.ft of volume (total), with displacement. What sort of port area and length would i be looking at. Also, i can increase the volume slightly, as that is with 1inch MDF

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…

Hey guys. I plan on purchasing two 12" Fi BL's. I will be powering them with two NINe.1 amps.....those are my plans. any other suggestions for amps are welcome. But the NINe.1's fit my bugget perfectly. I need suggestions for a box.... Ive been messin around and came up with this box. I will 45 all of the corners and seal her up tight. Should this box pound alright, but still sound dec.?? thanks here's the link http://www.subwoofertools.com/forum/ported...;Fs=27&CE=0

Is there like a list of subs that you guys can recone? or is it just american sizes? or what? Are there any rf's able to be reconed? or are they all foreign motors of some kind??<----T1's????? i want some ssd's soooooooooo bad but i need some $$$ and ive got 2 toasted T1's sittin here, jw wonderin if i can do anything with them instead of sending them to rf for $104 each plus shipping which is like $40 each, each way---- $400+ haha Thanks

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?
