12" ssd bp and flatwind options ordered it yesterday now i need help on dimensions for a sealed box any help or suggestions?

So I'm in need of a box for my Bl 15 in my scion tc.. I was going to get one built and shipped to me but it will take too long. Went to my local shop today, and they had one box for a 15". He said it was around 3.2 cubes which i guess is ok. Asked him what its tuned to and he didnt have a clue, said around 44 or something, which i would think is too high for the BL as i was shooting for 33hz. The box is carpeted, and higher up on the end where the sub goes in. Has two small ports in the sides. Price is $180. What im wondering is if the tuning really matters, and if it will sound like shit if i use this box?

jl 12 w-0 4 ohm. can this be reconed?

Well here are my dimensions for the blazer: Depth= 25" Width= 37" Height= 22" What kind of options do I have here? Like enclosure volume and tunning options. I was looking to use aeroports if possible... I would love it if I could get a 3-d look lol I suck at designing boxes... thanks

Just like the title says, I'm planning on getting an Fi Q12, dual 1 ohm with BP power. I was planning on running it off of this at 2 ohms. Will this power it properly? Also, will I need to do any electrical upgrades such as the big three upgrade or a red top battery under the hood? As of now, I'm running off of my stock alternator which puts out 120a and my stock battery. Thanks for the help, -schmizzle

I am not entirely sure about box dimensions and all. I want forward facing subs. I know 15's will work, but wonder if I could manage an 18. These are going in the bed of my truck with a fiberglass flat shell on top. I am pretty sure the depth of the bed of the truck is 20 or 21". Would I be able to build a box that will fit in this for 18's, or is it way to tight?

just wanting to know if you guys can or know if another company can. thanks!

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.

I don't compete and would like a SQ/LOUD SOUND QUALITY setup and am having the hardest time designing a box to use. Obviously Fi recommends a sealed enclosure and that's what I was going to do originally until I started playing around in WinISD. Now I'm completely unsure so I figured I'd ask you guys. How do you guys think a 12" Fi Q would sound in a 2.3 cu ft enclosure tuned to 24-25hz as opposed to a 1.3 cu ft sealed enclosure? I can't upload the WinISD output on my current connection but I will after midnight when I get home.

I have 2 rockford P2 15" d on a TMA amplifier 500.1 in a 4.5 Cu. Ft. Box ported. I'm in the process to get 2 Bl 12" d2 and I need the know if the HIFONICS BRUTUS BXi2608D will be a good option (cheap one) in a 5.0Cu. Ft. This will go in the trunk of a Toyota Yaris 5 door. My budget is pretty tight, that the main reason why I decided the BXi2608D. Here are the pics of my trunk Visit My Website

Where can I find some box cutouts for the old school black fiday x series 12". Can I use the new X cut outs or can I use the ssa dcon 12 cut outs. the dcons look like they are the same as the black fiday 12".

So if I get a DVC 2ohm BTL that means there are two voice coils, which just ONE can handle 2kwrms correct? So if I hook up 2kwrms to each, shouldnt that work? Or lets say 1500 on each coil for less heat? Yes yes I understand Im retarded, but you never learn if you never ask P.s. figured out my other question..

Has the title states, how do I get a 1 ohm load with 2 btls? My first previous subs where dual4 so I wired them in parallel. Do I need dual1 ohm? If so how do I wire them? Thanks.

Hi, I'm about to order an 18" btl I just got done going through the options i'm bit confused as to what ohm to get I want to run it at 1ohm the amp ill be using is a HCCA-D5000 monoblock my qustion is should I get a duel 2ohm and run it in parallel or what? how would I wire the sub if it was duel 1ohm, split the pos and neg in the box and hook up all the turmanals?

I'm looking for specs pertaining to a STRICTLY SPL setup using two BL 18's. What should the port be tuned to? How much airpsace do you recommend if I'm using a single chamber and acoustic coupling?

i have a 15" btl fully loaded. i want to compete in bassrace and maybe just for spl burps wise. i have about 5 cubes to work with. i kind of want the box to move alot of air for shirt tricks and hair tricks. is it possible to get high numbers with the two i want to compete in and still move alot of air like others do with this sub. just curious

ok so i have built alot of enclosures in my day but it has been about 4 years or so I have a mx15 in my truck right now with a 6" round port and its tuned to 32 hz sounds great i am super happy with it ok now onto the project I am helping a friend design a box for his car and a wedge style box is optimal to save the limited space that he has I will be using a BL12 and we will be making a ported box for it but the standard slot port wont work well for his application so we are opting towards a round port now here is where the issue arises I am unsure what size port i should be running single 6" or single 4" or possibly something else the enclosure we r shooting for is a f…

:bigclap: hi I am new here and I wanto to know How I cant buy a FI speaker. I need to aknow a telephone number thanks my email is [email protected]

scott i have 3 18's but 1 only has 1(the other 2 are fine) of the voice coils that works, there d1 coils what should i do

I am toying with the idea of putting 2 12" SSDs in a ported box. My original plan was to seal them, but I don't know what kind of output I would get. Could someone help me design a ported box for these subs? I am totally new to ported boxes so I don't know where to start. I'd like to maintain as much SQ as possible and gain as much output as possible. Dimension wise, my trunk could accomodate a box 39" across and 17" high. Depth is negotiable, depending on the size of box needed. Thanks in advance for the help.

I need help with box specs. I have 4 BL 15's going in a 2003 tahoe. I want to face them up( at the roof) and have these measurements; 48 wide, 28 high, 36 deep. Can someone give me a box layout or cut sheet with port measurements to make this a winner. Daily playing tuned low 29-32hz please. Thanks in Advance.

Hello Guys. I guess I could introduce my self before i start asking crazy questions..My name is David, I am a Firefighter, I live in Mississippi...I ordered one of the Fi 15 BL with the cooling option, Flatwind option and Universal setup..Daily driver...I am going to be powering with a Xt4000d Us Amps Amp. I have a Honda Civic and I will be using a ported box in the trunk..I have designed a box and was wondering if you guys that see these designs everyday think this one will do me justice...I used some measurements I took of my trunk and how I would like the box to sit...I will 45 all the corners in the box and build it as close to this as possible...Please look and tel…

I have Term-Pak and am looking at the graph for a box for my BTL It looks horrible. Is it just me or does the sub just plot poorly? I used the specs off the site. I'm using a model of 4ft^3 @ 32Hz

I notice that on the Fi website that u have options that u can add to your sub before purchase. What does these options mean? Flatwind coil? Copper Coil? and BP Power? Can i purchase this sub without this stuff. If i dont then how will the sub perform in daily uses? Oh yea, is there a big difference in hard hitting bass with the SSD 15 and the Q 15? Thanks.

Is 12 cubes net tuned to 31hz too much for 4 BL 12's? How about 140 inches of port?
