Building a wall for 2 x 18" BL's in my Ford Focus ZX4, as it stands now we've got 10.5 cubes per sub, my questions is how much port do i need? how much port surface area etc. etc. ????? Any help would be greatly appreciated. Thanks. Dan Soundmekanix SPL design Team

ok so I went and measured my trunk, the room I am working with is 36" wide, 20" deep, Now at the front of the box the height is 17.5" and at the rear the height is 14.5" Can anyone design me a box with 3.9cubic ft?? or where can I go to see some cut sheets of how this will look, I know it will be slanted front the front to rear.. this will be for my Fi BL 15.. thanks for all your help

does anyone know right off what diameter the sub cut-out is for a nice tight fit thanks

Hello, I currently have 2 15" q series dual 2 ohm with the b/p option .I'm running these subs in a sealed enclosure and would like to try them in a ported enclosure of 4 cft tuned to 30 hz .However, the FI Audio site doesn't tell you about port length only port area. I was hoping i might be able to receive some help here.

Alright so i have a BL 15 in my car right now. When i get money i plan on buying another one. But the one i have right now is D2 instead of reconeing it to make it d1 i was thinking could i just buy another D2 and then just buy another SAZ- 1500d?

scott, been sending some email this past few days, did'nt get any reply is everything ok? pls. check your email...thank you

i read the guide on here for the ssd's, and its a pretty wide range of sizes. I have plenty of room, and was thinking tuning to 32hz and about 16-17 cubes gross. Will be subs up and port back in expedition running off 1 saz1500d. Any suggestions, or does that sound like good place to start? thanks

I have a pair of 10" BL's. I'm running these with an MA Audio HK4000D, I've been running it at 2 ohms so they'd get about 1900 watts each. I'm planning to drop the ohm load to .5 and send them more power, at least 2500 watts each. What would the recommended enclosure size be for this increased power? I'll figure out the ports and such after but I want to know what size enclosure would be right for that amount of power.

Does the FI Q have any Shorting rings, do you guys use rings on any of your drivers

Hello guys, New to the Fi World and need some help making the right subwoofer choice between 10" or 12" before ordering. This will be a trunk install in a Honda S2000 CR so space is a bit limited and box will need to be sealed. System Build (so far): Enclosure "Sealed" Max 1.0 cubic ft before displacement.

hey guys .. im looking at building my own enclosure for my BTL 18" and was wondering whats the minimum cubic feet as i have a limited area to work with Thanks

I am going to build (or have built) a 1.88 cu.ft. enclosure tuned to 32hz for a 12" Fi BL. I want to put a round port in the box or multiple round ports or even a triangle port. Can anyone tell me the dimensions of the port? I know there are tons of calculators out there but i don't know how to take in account port noise and all that fun stuff. I don't know whether to put one port or multiple or anything. Thanks in advance!

here is waht i have to work with... 11" tall, but that doesnt leave much excursion room, so maybe 10"? 32" length 16" deep im thinkin about a SSD 10 or 12 ... idk if 12 can make it in the space... woofer should face sides front or top, probably a must that its on top anyways because of hieght limitations.. i want to only be able to see the carpeting, no components or sub showing.. will be 500rms for now, ill get a 1000 sundown soon enough.. its for a 63 impala.. so help me on ideas friends.. thanks!

whats up i was wondering if someone could tell me if a 5.573 CF. after port and sub displacement enclosure with a port thats 12.5"s tall 5"s wide 20"s long tuned at 34.73 hz. sub up port back would be a good box for a 18" fi bl or would i be better off going with a 15" bl let me know thanks.

I have two fi q 15 w/bp power that I need to ship in for recones. could you please send me the info that I need to go about doing this? do I pay before or after they have been fixed? thanks

I was wondering if 6.75ft3 net volume at 32hz is good for 4 FI BL 12's in a ported enclosure with about 6,000 watts of power?? 6.75ft3 net volume, 32hz tuning.

Does the recone kit come with the glue if not then what type do i need?

i have been searching the forums and technical advise.... but i dont see anything about FI speakers in a sealed application. i want to run 2-15's or 2-18's in the backseat (fiberglassed in) of my caprice, however i dont really like running ported enclosures. is sealed not an option with FI speakers?

does flat wind coil and bp power add to a 12" ssd? how about bp power on a 12" Q? just thinking about future upgrades. thanks.

What sort of rules apply when constructing a ported enclosure. I know the basics like tuning and port dimensions. But do subs need to be spaced a certain distance appart to be effective...? Things like that! Cheers

in my first thread i stated that i had a mtx tc4001 that i wanted to use. but it woouldnt handle the 1 ohm load that the dual2 would have or it would have a 4ohm load if i ran it in series. if i get a D1 and run it in series wont that show a 2ohm load to the amp?

Just as the title says, I may be getting 4 Ssd 12s in a trade and I'm. Doing a blow-through in a Toyota pickup and was wondering if they. Would perform well in a 4th order band-pass. Thanks

I traded everything i had about 6 months ago, well, guy gave me good deal on getting all back and some new stuff he just bought. Anyway its 2 BL 18s, and 2 sundown 1500ds strapped. I had subs up, port back, 20 cubes before port and subs tuned to 33hz. It sounded great and definitely had the lows. box before was this: then i had new design done for wall behind front seats, same tuning, and specs, both boxes with 200+ square inches of port, wall box: Both boxes designed by chris at fishercustoms. I never use backseat anyway, but not sure if will make big difference as in louder if i go with a wall. any suggestions? or just go back how it was?

ill be ordering the 12" ssd's soon and temporarily they will be going in a prefab (i hate prefab) dual twelve box with the port in the middle. 2cuft per woofer. when i put my other woofers in there they were loud as f**k but when i played a song like bass mechanik moonstone that has a 20hz bassline they bottomed out and almost broke the voice coil. heres my dilemma i have been seing a lot of people use the boxes that are similar to the box i have exept the port isnt in the middle of the woofers its on the side.ex: http://subwoofertools.com/forum/ported-box...mp;Fs=&CE=0 all of the vids ive seen they either burp the woofers or they play some crap from jeezy, never any…

is my rockford fosgate t20001bd at a 2 ohm load too much for my 2 q18 d2's? its a 2 ohm load at 1600wrms. thanks!
