Fi Technical

I think it's just me, but there are some random gaps if you will. I have some pictures from my slr that i'll upload in a while. Just want to make sure theres nothing bad. Thanks

My current box pounds in the 30-32hz range and I love it but I also love to compete in local competitions so I need a new box for all out spl. My trucks frequency is 41hz. Can someone help me with the correct box volume and port specs for a box that will peak at 41hz for spl only? The subs are a pair of Fi Bl 18s. Thanks.

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..

a question for the man shawn fleming and any body else that know about spl boxes.for spl only,which box would be louder for a btl-18 with 5000 watts.a 6.2cf box with 98 inches of port,tuned to 64 hz. 7 cf box with 114 inches of port at 64 hz or a 8.5 cf box with 138 inches of port tuned at 64 hz also.for spl burps only.this setup is going in a astro van,4-btl's 18's.trying to find best box config.with port on driver side.all thoughts are welcome and valued.thanks BP.

I want to build a SPL enclosure for a show coming up and wasnt quite sure about size and port. What I was going to build was... 42" x 15" x 10" with a port that was 10" x 4" x 21" Will this be good ?

Hey everybody i was wondering if I will get a better spl level if i face my sub towards the front instead of the sub facing the rear of the trunk.... My enclosure is 3.0 cf3 tuned @ 35 hz... Fi BL 15.... the car is a 05 kia spectra lx

Wondering on box size for strict SPL setup. Would it be best to use the 3 or 5 cubic foot box or some other size. Tuning will be 54 hz. Not sure on port size yet but thinking 150" per sub if I use the 5 cubic foot size and 90 on the 3 cubic foot size. Will be running 2 Sundown Audio SAZ-3000D to each sub off a 16 volt system. Willing to listen to suggestions.

I will soon be running a fully loaded BTL 15 in a 4 cu ft ported box. Which tuning would be better SPL wise, 45, 48, or 50 hz? I know it is a bad question because it varies, but what has been a good SPL tuning most people have been using? Thanks Dustin If it would be best to build a bigger box would a 4.5 cu ft box after displacements be a good volume for SPL? Thanks. Dustin

I just designed my box and came and up with 12.37 sq inches of port per cube is that a little low? What does more sq inches of port per cube do? I also came up with about 4.03 cubes per sub before displacment I want to do a little larger what does everyone I think? My dimensions I used are 23width x 34height x 49 length. they will be in an 05 f150 with two kicker zx1500. 1 amps powering them for now will upgrade power. I know they give generall recomendations of 3-5 cubes per sub and 12-16 sq inches of port per cube. What is everyone else running? and what should I tune to? I did 27 hz my amps lowest is 25 hz and the way I understood what fi said was 2 above your amps lo…

To figure out the square inches of port area needed per cubic ft of volume, do I just multiply the vent width by vent length? And then I just take that number and divide it by how many cubic ft the box is? This is what I'm just guessing as I'm not sure of this. Please help.

Hello, i'm looking at getting a Fi Audio 12" SSD sub. So I was wondering if a square port of 29.25 is alright? My box is 2.1 @ 33Hz. Thats after all displacements. I haven't build a ported box before, so i'm learning how to.

I am about to purchase a single SSD 12" to pair with my Rockford Fosgate T1001-bdcp. The amp is 1 ohm stable, but the birth sheet shows only about 50 more watts when compared to 2 ohms. May I please ask whether you recommend going d1/serial to 2 ohms or d2/parallel to 1 ohm? I will be going with high QTS/sealed and cooling (personal preference). Thanks!

A while back i bought 2 SSD 10s with no options. I am still confused on what to push them with. I have my eye on the Rockford Fosgate T-1000bd. Any suggestions would be great. Also im still not sure on what enclosure i want to make for them. i have run sealed in the past but not sure if i should go for ported with these. Thanks in advance.

Is the recommended sealed cabinet size of 0.2 to 0.6 cu ft after displacements given in 2007 for the high QTS driver. Also does anyone know what the high QTS is

i have a 10" ssd on order and am going to get started on a box was just wondering if someone cd look over my design. its a truck box its 35" wide 14.5" tall and has a 5"/9" angle / wedge. im using a 3" psp aero port that will be 17" long. running about 750 wrms. does this sound good? thanks brandon

Hello I have a ssd12+bp running off a Alphasonic 1200da at 4ohms. Rms is 1200 at 4 ohms BUT my electrical system is stock so with around 50-70 amps at 12.5-14 volt I believe Im only getting 550-700 watts to my sub. The 12 is in a slotported box with 1.6cuft tuned to 34 htz. I built the box for 2-12 so they each have their own seperate enclosure, but I can not see another SSD 12 in the near future cuase times are tuff. My question is this- If I build another box for my 1-12 at say 2.3cuft with a slotport tuned to 32 htz, what do you guys believe the difference would be? more SPL? I really would like it to BOOM harder, louder, higher spl. Im not into SQ so if that goes down…

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…

Hey guys, as the topic says I have a problem with a SSD 12... the spider feels very weak in a spot like there is a crack under the top one. So my question is will it be fine to run like that? (i don't know how long its been that way but it worked fine till the day I took it out) or do I need a recone so it doesn't get any worse? Thanks

I cut a box according to the ssd cut sheets, and it is in a 08 mazda 6i sedan (non hatch model). well.. Downside is it does not fit with the sub facing the seats. I gutted the trunk to bare metal to see if it would help me try to squeeze it in.. NADA. I PROMISE you it does not fit any other way unless I somehow build it in the trunk. So my dilemma, is that the sub is pointing straight up towards a panel, and a lot of the bass "energy" is soaked up from it. Is anyone knowledgeable to give me the smallest possible dimensions for 33hz ported box? I suck at numbers, they give me headaches, and I failed alg. twice in college.. lol. I know that sounds lazy, but sub boxes are n…

Hello. I have a 1999 Dodge Ram 1500 regular cab, and I want a "system". I have figured up that I have about 1.7-1.8 cubes of space behind the seat. I was originally wanting 2 12's, but I would still like to have the massive amount of storage space that Dodges have. So I was just wonding if I could fit an SSD 15 behind my passenger seat. The top of the box will be 6.5" deep, and the bottom will be 10.5" deep. The reason for going with a 15 instead of a 12, is just for the coolness factor of saying, "Yeah, I've got a 15". Thanks for any responces!!!

Hey guys I'm looking for blue prints for either a single or dual 15 inch ssd ported box with optimum area space. I'm not new to stereos or box building, I'm just way to lazy to design my own box. So I was wondering if there are any blue print boxes laying around like element designs puts out on there site. Thanks in advance and hopefully you guys have some so I can get to building.

I sent an email asking this but never got a reply. I was wondering if i could seal up a SSD 15? If so what would be an ideal size for the enclosure? I checked the specs under the SSD section in the sticky thread but all i could find was "we are still testing sealed enclosures" etc. Thanks.

Hi. Has Fi or anybody had any luck with running the ssd 15's sealed. I want to change to a sealed for my next setup. Looking for daily driver/occasional bassracer. Isnt' thomas rourke jr using his ssd 15's sealed? I was thinking of running 4 ssd 15's sealed off my Atomic 5000.1.

After first seeing the specs on the website, I noticed there are a few necessary specs not included. #1: I noticed the xmax, but nowhere did I see the xlim. #2: Recommended type of port(s)? (shape/size/depth) If I list the specs of my vehicle, maybe someone can get an idea and throw me some info. If any other info is needed, just ask. 1995 GMC Sierra LT ext cab 6.5ft bed. Rear seat bottom and back will be removed. .75" MDF enclosure with internal dimensions of 45"W x 30"H x 25"D. Subs will be up-firing. Should ports be front, rear, up or side firing? Where should the ports be located in terms of speaker location, between subs, at corners, etc? I will be aiming for…

what is the smallest sealed and ported box that i can use to put 2 ssd 18's in.
