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.

yea guys..umm ive already done the big 3..no biggie...and ive got a rebuilt alt puttin out 300 amps........but i was wonderin what would be the least and optimum output from an alt if im going to be runnin 2 fi bls..18s ..thnx

So this is how much room I would like to use, but I have more room if necessary (I need some trunk space :laugh:) My dimensions are 33x21x17 and here is a picture with how what space I would like to take up. Just post your input on if this is good or if I should add more space for the box and how much! This should be around 6.817 cubes without any displacement. (btw this picture isn't mine I just googled what an 05 equinox trunk looks like, and no those side panels do not come out) hmm for some reason the picture came out a little blurry, but I think you should get the point and for the height I can also do up to about 21 inches so if i wanted to mount the sub back i cou…

What is the most efficient subwoofer you guys build in your standard lines? Please, only someone from FI on this one.... -Mike Edgar

I have 2 Konaki 12's with Incriminator Audio recones on them. Overall they sound great and hit the lows great, but the power handling is lacking. I have them both on a Crunch GP3000D-Pro which is putting out between 2500-3000 watts given my electrical right now. The amp is set correctly and the system thumps hard, but it seems like they bottom out wayyyy too easily. I play a lot of low stuff (<36hz) and when I turn it up too loud, the subs bottom out. Basically, I'm wondering if Fi would have any options to boost my power handling to 1500+ watts a piece and maybe some spiders that would stay stiff and allow me to play low frequencies at high volumes without bottoming o…

I've had my Fi Q 12" (no BP option) for about a month and a half now and its been making a strange vibrating noise at certain frequencies since I bought it. I thought maybe it'd just need broken in a bit since seems to be hitting really well and doesn't sound distorted. But its still making the noise as much as it was the first day and its been broken in plenty since then. I made sure that it wasn't anything in my car rattling. I used an extra long run of speaker wire and put the box outside of the car and it was clearly the sub itself that was vibrating. Its audible with certain sounds in certain songs at a moderate volume but actually gets pretty irritating at high volu…

I'm getting ready to build a box for a ssd18 copper coil. It's going to be in a 1999 yukon and I was wondering what would be the best specs and port design and placement for optimum bass response. I love the really deep bass, but don't want to lose too much sound quality( some is o.k though). Any help would definately be greatly appreciated. Thanks everybody that helps me out ahead of time.

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.

Whats the best kind of wood I can use to get the full preformace out of a 18'' FI.BTL with these specs? Dual 2 Ohm,Cooling,HiXm Coil,Induct heat ring,And Daily option. I plan on buying four!!! Also the recommended option is 2000 Rms but Steve Meade told me he gives his 5000 Rms each he has four also. ''audio-neon'' told me ''meade knows how to build enclosures to compensate for overpowering the woofers thats why he gives them that much power''. If thats true how will I make my enclosure inorder to do that if I plan on overpowering the subs. Is that a good thing if I have a enclosure do that or just stick with 2000 Rms each (or maybe 2600 rms if so). FI.BTL Specs (BTL18) …

I finally ordered knukonceptz wiring today, and it should be here within a few days, and i'm planning on making one last trip to the hardware store. I was planning on screwing the sub in, but i really dont want to anymore because 1. not sure if it will be sufficient and 2. the image of silver bolts coming out the sides of the black sub seems badass So what size (diameter) bolts should i ask for? The hole is 3/16, but do they make a bolt that size? Thanks for reading, Mitch o btw, the sub is 18 bl, doubt it matters though.

Doing some box designs and wanted a little help on picking what hrtz to tune the box at. I read the post from Fi about tuning and it says anywhere beteween 30-37 hrtz. I will have around 8.5 cuft for each sub and wanted to hear some suggestions on tuning. The enclosure will have the ports facing twords the rear with the subs mounted on the top side of the enclosure. I listin to mostly rap music and want it to be loud as it can be. The subs will be pushed by 2 Alpine PDX 1000.1's for now, but down the road will be pushed by 2 PDX's on each 18 1 on each voice coil at 2ohms for a total of 2000 watts to each sub. Thanks, this site has helped me alot so far, the best sit…

Sup guys. I currently have 2 15s in my car and the box is around 4.7 cubes. If i got 2 15inch btl fully loaded subs would i have to increase the cubes of the box? Thats my max cubes that can fit in the car

So I just recieved my 15" SSD with copper coil in the mail Thursday. I originally planned to go sealed in about 2cuft, but I have about 3.1cuft after all displacement to play with, so I was thinking about porting it. I wanted the install to be strictly sq, so I was thinking about 28Hz or so. My question is, has anyone here tuned it that low? If so, how's the sound quality? And if no one has, what tuning would you recommend for a sq setup?

I've read and read. Perhaps under the explaination of options, this could be added to the flatwinds description if it holds out to be true: Does Flatwind add power handling and excursion at the expense of sound quality?

I'm the one with the konaki motor ! Please recone it. I've sent you guys emails and nothing yet. Its been almost a month. Give me dual 1 18" with the strongest softparts available . K-thanks bye. My email is [email protected]

ok so i was thinking of either getting 1 or 2 fi q 12's or 1 or 2 fi q 15's because i want a little more sq, but i like listening to rap sometimes and i was wondering how low a q 12 can play

Is it possible to order just a recone kit and diy? If so what are the prices on 12" and 15" BTL's anyone know? Also is there a way to contact Fi directly other than e-mail like a phone number?

will it be safe if i'm smart with my gains? is bp power a must? i plan on not using the full 1600w. because my electrical will crap. 2.24cuft 34hz thank you

I have one SSD10 D2 with copper coils in a sealed box with about 600 watts rms coming from a Phoenix Gold Ti600.2 I know going ported will give me more output but i'd really like to stay with the sealed box I have because it fits perfect in the truck. So, i've been looking into getting a 1000 watt amp like a Sundown 1000 or Alpine PDX 1000. Would this upgrade be worth it or should I stick with what I have?

I have emailed the address available on the site and havent received a reply. I need the specs for the new 18" btl fully loaded.

I was wondering which setup would fit better. i currently have a kicker 750.1 and i was planning on gettting a fully loaded 12" duel one ohm sub and running it at 2 ohm. I was wondering if that amp would be enough. If not then I plan on getting a fully loaded BTL 12" duel one ohm sub and running it with a Lanzar2000D. Thats supposed to put our 2000watts @ 0.5 ohms CEA rated. Which setup would work out better?

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/

Which would get louder 1 15" Bl in a ported box or 2 12" ssds? They would be powered by a saz-1500d. im wondering which would get louder and sound better. any help would be great.

what add ons should i get on a 15" BL if i plan to use it daily powered by a sundown 1500?
