SPL & SQ / Fabrication

Hey guys I was wondering if I could get some help for a box design. I messed up my first design as my box fits inside my car but I FORGOT to measure the opening of my trunk to put the box in which doesn't allow it to slide right in. I am coming to you guys for a design for the Fi 15" BTL. And the car I have is a 95 Honda Accord. Max width I will go is 35" and the height will 16.5". Was looking for maybe 4 cubes of space @ 35Hz. I would really appreciate the help and thanks in advance! -Curt

Im looking for a box design for 2 15" Mtx 9500's for my 07 civic si 2dr,(H16xW40xD26 Roughly) Im looking for ported,trying to do subs facing inside the cabin with port the same. Any help will be much appreciated....... Mtx recommends 2.48 net enclosure per sub(from there website)(W 24xD 17xH 16)Port 2"x14.5. Now my trunk dimensions are 40w x 26d x 16h so i think i can make this work in my trunk...Right?just by taking 4" off the width and adding it to the depth and then make a 4" port........Can someone help me out with this....PLEASE??lol I listen to mostly rap and rock(for port tuning) Which of the following is the sub displacement?That would have to be minused off the…

I have read a lot on the subject, but I can't get a final answer. Like a lot of people in my country (we have small cars), I have limited space in my trunk, but still want to use a ported box. I've read that round ports can make me save space. But I don't understand how. The same rules should apply : 12-16 sq inch of port area per ch ft. What can I expect for a 3.5 cu ft box ? I would like to make a smaller box so that my amps can breathe Thanks

I remember playing around with making boxes and stuff and had some different software. I had somebody guide me through it before, I had a box deign for my other truck. But with it, I have to make some decent modifications to it to put a box in it. With my Jeep I can just design a box, go pick up the stuff, make it and drop it in. I think now that I can do that, I will actually pay more attention to how to do a box, have more interest in it. I was recommended subs up port up on the drivers side, not sure if it will fit or not. The max exterior size the box can be is 41.5"w, 16.5"d,21"t... I'd like to design a box myself but obliviously get some help with it. I think if I …

Are 45*s needed with in boxes that use PVC tubing as ports? Also I designed my box using Win ISD and was told to make the box roughly 2.0 @36hz and use 10" of 4" pvc. Now does WIN ISD take in to account for the space taken up by the PVC or do I have to make the box larger?

I designed Shogen a box, I just want him to see what it should look like when he's done. And I SUCK at Sketch Up. Who's good?

So I've been reading a ton about aeroports and I've heard they reduce port noise and take up less space therefor reducing box size. I want to do two SA10's in 3 cubic feet tuned to 33 hz. I've been trying to use all sorts of different calculators and such trying to figure out port sizes and what not but its not coming together for me. Basically I want to know how you figure out port length and diameter as well as port displacement in the box. Also where is a good place to get these ports from. I'm going for a really nice sounding setup that can get loud if I wanna show off a tad . Any info I didn't include just ask and I'll do my best to fill in the gaps. Thanks BumpinAl…

I've got one of the few remaining 18" Inhumans that I desperately want to hook up and listen too before I get rid of it. I designed up a quick box in WinISD and came up with these numbers. How do they look to everyone? 8ft^3 tuned to 34Hz 98" of port, 20.31" in length Nothin special, just a good daily driver box.

so i used the re calculator and designed a new box for my r.f. power hx2 15. now what im wondering is when i add bracing will that affect my tuning? and how should i do the bracing?

It's about 7.4 ft^3 with a 13x6.5" port. Two 12" type r's are going in and will be running at 1000wrms. EDIT: What would be best to tune this box at? I'm doing daily and want it to sound good, not just loud. EDIT 2: Listen to mainly rap.

my box is going to be 7 cubes after displacemets. box is 20 inces deep (so one port side can be 18.5") 112 inches of port area, 33hz my question is, can i do two ports, each 18.5"x3" at 12" long for ~33hz would that yield a net port area of 112 and keep the 33 hz tuning? if not, how do i go about calculating this? im going to try to do a drawing real quick to help you see what im doing

hey guys i got a question for ya. im building a box for 4 15 fi ssd's and i was wondering if a box built at 15.5 cu ft. net and tuned to 32 hz with 200 sq in. of port. its going into a blazer. think this box will work? any info would help thanks.

Wood Thickness 0.75 Height 30 Width 38.5 Depth 15 Sub Displacement 0.42 Port Height 28.5 Port Width 3 Tuning Frequency 32 Port Length 29 3/16 I get Around 6 Cubes at around 32 hz, after sub and port displacement...i just want to be sure they are correct. thanks.

considering doing a box with aero's wanna tune it lower also around 30 hz right now its in 3.4-3.5 cube at 34 hz on 3k rms to get the tune i want and my depth issues guided me here, i hear you need to have roughly the diameter of the pipe distance from flare to back of box for it to be right? so final figure would be 4.25 cubes at 30 hz with 1 6" Aero at 16.5" for that tuning and thats from flare to flare. Should i just go to 2 3" aero's or what do i do hear, because i will be going 16.5"+6"+1.5" for the MDF im too close to the rear hatch, it would be like 3-5" from it

just started my new build for my fiance's brother the box will be for 2 jl 10w3v3's

I'm trying to figure out my next box. The program I'm using is tells me that my port will be 5Tx10Wx17.5D. Now how much of an effect will it have if I was to change the opening to 3.5Tx11.5Wx17.5D?? I'm looking to tune it to 34Hz. Thx from the help.

So I have two 21" dp's and I am wondering, what is a good rule of thumb for port area on a spl box? As far as square inches per cubic ft? I have never done a spl setup. And I am planing on doing two slot ports for spl and plugging one for daily use. And would 10 square inches per cube too small for daily beating? Also may try something like four areos to keep down on internal space.

When doing a blowthrough setup in a pickup, will it really make a difference as to whether the truck is extended cab or standard?

Working on some fiberglass corner enclosures on an upcoming build for someone and i noticed that the corners that they will be installed in are slightly different. since i was going to begin by making the backs to rest perfectly flush i am wondering if having slightly different airspace for each side, say .1 of a cubic foot. would cause problems. I would say the left box will be about .9 sealed and the right would be about 1.0 if anything. should i add an extra piece of MDF to the bottom to compensate? i didn't know is the different Fs would cause some type of clash in the response

Time for a new box and im gonna need alittle help. Not really good at box design so thats where yall come in handy. I have two of the new 15" BTLs and i know the box from my x-cons are holding me back at this point. Im figuring i wanna go with 8-9cuft tuned to 34 or 35hz. Port area is whatever it needs to be for a good mix of daily and spl. Im assuming 100-125 for port area will do the trick. Needless to say if you can design me a box and the cut sheets id much appreciate it.

Would it be better to but 45's here or would it be bad? The pics will explain it better. Option A. Option B. There are two, one on each side of the port. The box is 48" wide and the port is at the bottom in the middle, and is 30" wide. There is a 45 on the back opposite of these.
