So is a 3.9^3 box too big for a single Btl N2 12" on a Saz-2500? I know that the spec sheets say 1.75-2.5 cubed. It was professionally designed and the person who designed it says that it still falls within the thermal/mechanical specs for this sub, so they dont understand why i am questioning its size. I don't want to damage the sub with over excursion though, so any input would be great. Thanks!

Wheres the BP option when buying the 12 SSD? Is it not offered any more?

Hey everyone. I am a new member but have been reading a lot of threads here for a while. I recently purchased a 12'' SSD with the copper coil option for my 03 S-10 ext cab. I plan on throwing the recommended RMS or more at it. I am now struggling to figure out what type of enclosure to build for it. I have read good things about sealed and ported for this subwoofer. My goal is to have a good sounding setup that has the potential to be loud if I felt the need. I want to build a ported enclosure but am afraid of port noise seeing the enclosure is in the cab with me. I can build a sealed enclosure also pending peoples thoughts on this. If anyone with knowledge on desig…

I want to build a console box in my single cab truck and im trying to see which would be the best. Setup 1: 2 Fi X 12 D4's ported Setup 2: 3 Fi X 12 D4's sealed Setup 3: 2 Re SE 10 D4's ported or sealed Setup 4: 2 Fi SSD 10 D1's ported or sealed Only reason im considering Setup 3 because I can save about 80 dollars on the subs over Setup 4. And im trying to be louder than a buddy of mine with one RE SX/BL 12 Hybrid ported as a console box.

So im designing an enclosure for my btl thats coming in for my crew cab truck thats going to sit on top of the seat and im not sure what the best orientation for the sub and port are for trucks for the most spl. Is it sub forward port up? Sub up port up? Heres one design that i put together, about 7.75 cubes net after displacement, 32 hz, the port will be facing up and sub forward. Are there any design flaws that you guys can see with the port? Is there enough space between the end of the port and the back wall of the box? Any other recommendations or comments?

well im trying to plan my setup... already got it down to a fully loaded for daily driving BL 12inch subwoofer to go with my RF amp that pushes 1602watts rms.... the box will be around 2-2.5cubes after displacement... have to run all the numbers after i gut my current setup.... and well i plan on running my same box setup in my civic to have it front firing into the cabin... and well i have a slot port in my box but im wanted to rebuild my trunk setup and this time instead of having a slot port id like to use some aero port or ports..... want to use some 4inch aero ports for the setup.. BUT im always HORIBLE with calculating ports.... ive always had people run the number…

Hi, Subs are 2 FI ssd 12 D2 BP Power . I know they are recomended for a 1.8 to 2.5cf box, Due to the room available I can only go up to 3.17cf after displacement and bracing with 50sqin of port. tuned to 33.5hz? Do they perform well in smaller than recomended enclosures? will be running about 2.5krms to them Thanks

Hello guys! I am new to the forum, but recently got back into the swing of car audio. After 10 years of not having any bass I'm ready for my new build. Right now I have a basic setup in my 2011 Toyota Corolla S Kenwood KDC-X596 H/U Alpine Type R SPR-60C Components up front Alpine Type R SPR-69 6x9's in the back Hifonics GLX 100.4 running mids and highs Hifonics X1000.1 running the sub I'm going to pick up an SSD 12'' and run it ported. My question is this..... I have worked a lot trying to figure out the appropriate dimension in order to obtain 2.25 cu ft of internal space after sub and port displacement tuned to 33Hz. Each program gives me a little bit different nu…

If I were to order 3/4 MDF boards from Home Depot. How much should I get? I want to get a LITTLE more then I should get, but not an overload of it. This is for a 20H x 25W x 20D box that will hold a 15" BTL. Thanks, -Curt

I've decided on the 2 12" ssd's. Really excited for it! NOW..... the box Ive always wanted to try an aeroport so i can adjust tuning and uses less space. But heres the catch. I dont know what to do lol. The box dimensions im looking at are: Height: 15.5" Width: 31" Depth: 16" According to RE calculator (which i know is off a bit) is about 3.5 cubes with no port. With those dimensions above or similiar, what aeroport do i get!? where do i put it on the box? I want it to be tuned to 32-33 hz thnx guys !!!

Hey, i recently built a box for my 2 Fi X 12's, it is a ported wedge box 4.37 cuft after port and sub displacements. I have a 4 inch ,"precision port", flare port and is 6 inches deep. The problem is that the sub closer to the port moves more and im thinking that i could get more out of the subs if they both had the same movement. A little confused.. i was told that it would be louder if i would have divided the box and but two separate ports, one on each side rather than one on the passenger side. By the way i have them on a Autotek MM1000.1D

So i am about about to add another BL to the trunk the both will be dual 2's, daily, P Chamfer, and univeral features.. Im looking at sundown audio for my amp. Which model should i go with? any reccomendations, sundown or any other brands?

Have any of you used an SSD 10 for home subwoofer use and does it work well. I have a high quality 2 channel stereo system at home and use a subwoofer to fill in the bottom end. My present sub has an RE Audio SR10 dual 2 ohm driver and a 500 watt rms amplifier. I am wondering if I would get an improvement by using a Fi SSD 10 dual 2 ohm driver. It would be used in a sealed enclosure to get best quality bass and be the high QTS version. Any opinions would be welcome. I am a bit confused about cabinet size as I keep seeing different optimum box sizes quoted, ideally I would like to know what the HQTS actually is so that I can model it in WIN ISD. I assume all other T&S …

Here is the Max Dimensions im working with Height 1 18.5" Height 2 23" Depth 17.5" Width 38.5" 2 15" Q's I figured out if I got with 65 square inch of port (which is only 10.8 per cube) I would have 5.6 cubes internal volume @ 32hz will this be alot louder than 5.2 cubes sealed? I could go with external ports and make it something like 5.8 cubes maybe, Box will be gettin done next week and I'm freaking out cause I want it to be loud Do you think sealed these two 15's will still be alot louder than my old 2 12's Kicker CVX's in a 3 cube ported to about 34hz? I'm gettin a headache just thinking about it

What is the recommended amount of port area for an SSD with copper Coils? Think I need to build another enclosure but I want to get everything panned out before I do so..

IAM LOOKING AT BUYING SOME FI AUDIO SUBS 18'S I WILL BE GETTING BUT IAM HAVING A HARD TIME FIGURING OUT WHAT WOULD BE LOUDER 2 SSD 18 INCHFI SUBS OR 1 BTL FULLY LOADED ANY HELP ON THIS WOULD HELP ME THANKS!!! ill be using kintek batterys in a ported box in a crown victoria what iam looking for is for people to hear me far away as well as shakeing the hell out of my car lol which do u think would be best 2 18ssd or the blt loaded18

Hey, just wondering if anybody has had good results with an 18" SSD in a sealed box?

I know no one probably knows really for the 09 lineup but would the BL 15 really get THAT much louder than the 12 if they were both fully loaded? Or would it be a noticeable difference? I want to know if it's worth waiting however much longer for the 15, or if i should just order the fudgeing 12 cuz im sick of waiting lol.

I wanna do 2 15" subs (read Fi BL's) In the back of an 1990 Formula.........think it can be done without having a sealed box or a wall and still having a backseat?? God I hope so. J

Ok, so i have figured out what i am going to get. 1 fi btl 18 and ma audio HK4000D with pioneer premier DEH-P980BT deck. I need some help building a box, just need a very simple one I have a dodge charger and the dimensions we have to work with are 31w x 14 1/3h x 30depth and MDF 1inch since the height is only 14 1/3 i am going to have to slant it, can someone help me with a drawing or something, like where the top panel needs to slant in order to have enought room to fit the sub please tell me what you think and if you have any advice please tell me. Thanks, Madison

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?

I am truly worried about this since I am eager to get a X10 or X12 and it has to deal with power issues. I have an Arc Audio XXD 2080 and it des 240 x 1 @ 4 ohms when bridged. I truly have been wanting to get a Fi Audio sub since three years ago but would like to know would the amp and the X10 or X12 would work together hand in hand or would it be a total flop?

Just a quick question, I planning on buying a 12" Q w/BP and I need to build an enclosure, going sealed. With dimensions of 19w 13h 11d, do I need to add int bracing? I was thinking just a strip of 2x2 along the top, back, and bottom. If it doesn't need bracing I can just make the box a little smaller to give the same volume Thanks, Chris

ok so heres the deal. I currently have a 12" btl in a 2.25 @ 32 enclosure being run off a crunch gp3000pro. It is loud don't get me wrong, but of course I am always looking for a little more. So I am thinking of building a new enclosure for it and I am just looking for ideas. Thought about tuning to around 35, but not sure if it would be worth it or not. This is the first single sub set up I have had so maybe I am just setting my expectations to high, i dunno. I figure I might as well try a new enclosure before I jump into a whole new set up, so any suggestions are welcome!

So my parents are not goin to let me put my new fi btl 18 fully loaded in the cab of my truck. i want to know if run the port into the cab if it will have close to the same output. It is a 7.97 ft3 box at 30 hz. I know it wont b as loud but how much will it effect it.
