SPL & SQ / Fabrication

...that is all. -Nick

Hey all. I have my Fi SSD 15 in a box right now that is tuned wayyy to high. So I was crunching some numbers for a new box. Here are the specs, can you all look over them and see if everything is correct please? 28" wide 17" tall 28" deep Port: 4.5" wide 15.5" tall 41" long Sub up port back. 3.9 cubes net, @ 31hz, 17.88 sq in of port per foot Also with that box, should an SSD 15 hit the lows pretty good?

well i had the having the box where the backseats are located at, since i barley got the car and not ready for a wall i had this thoughed in my idea has it been done before? how does it sound? any mechincal noise coming from the woofer you think? idk if i worded it correctly. its ethier my recone them to 18's or recone them to 15's i currently have 2 10's dc audio xl woofers any input you guys? no idea if its done before to be honest, is my idea a complete fail or another way to feed my goal of getting louder any input will be helpful

Can someone help with ideas for a new enclosure? Wanting to figure out the port velocity and everything . Model everything right for this one. . Trying to get a new computer so I can do everything my self and learn everything but in the mean time need some help.

Has anybody had any experience with Rear-Firing in Single Cab? I plan on doing this or downfiring. The only problem with downfiring is the max bottom depth I can do is 12.5" so the 12" sub will be on the surface of the wood just barely. I'm worried it might not be enough support because that will leave about 1/2" on both sides of the Sub Hole. (Where ever the sub will be, it will at least have 2 baffles.)

which way should i do my box design for a btl 18'' with two 6 in aero ports. sub up, aero back?

Alright. Here is what I have to work with. The box will be for a 12" ICON. I want it ported to play low and deep. As you can see from the picture, the only dimensions I have play on are X and Y. I know nothing about round ports so help me out here. The ports coming out the top will be placed directly beneath my open 6x8 reardeck holes.

i have 2 18" treo ssx's my box now is 9.99cf gross with a 100sqin port port is 4x25x21.5 deep after all dissplacements im at 7.68cuft treo reconmends 8cubes after dissplacment im doing a 150.7db at 34hz burp with 1 rd audio d9 amp but can you help me with my new box i plan on keeping it 8 cubes net but what can i do with the port to get more spl but still play low notes and keep it a dailey driver here is a link to treo ssx page click on the view specifications at the bottom of this page for the specs treo web site im running the amp at .5 ohms and this is a hatchback car im doing subs up port back please help me out thanks

I am going to start on this project very soon so I thought I'd start planning right now.. Here is what I wanted to do.. I did not want to sacrifice my whole cargo area so I got my sub box made to take up only half of the whole cargo space so I can have half of the space to store things or whatever.. And then I realized that I have no place to mount my kicker 2500.1 which is a fairly large amp so I decided that I would want to build a false floor with plexiglass on the other half of the cargo space in front of my subwoofer box.. (as of now my amp is sitting on my rear seat folded down (i definitely do not like it at all and I do not want to mount my amp on the sub box as …

Anyone wants to donate some blueprint of boxes that could fit here sub is 9515 w/ strapped saz1500 amp Length - 31.5 inches Height - 18 inches Depth - 22 inches These measurements are the space left to be exact, no box yet. Assuming 1inch MDF will be used and I'm eyeing for 4.5cu.ft. or 5cubes plus port tuned to 40-42hz. Sub is facing up and port is facing the rear hatch door. With the given depth, there's a 4inch gap remaining before the box/port would hit the rear hatch. Id appreciate your suggestions. Thanks

Hi, Can anyone help me with a box for one T3 Audio TSS 15 for a 1997 Acura CL? The CL is the Acura's version of a 2 door Honda Accord. My amp is a Sundown Audio 3000D. I can use up to 4.5 cubic ft. The box needs to be for SPL. Thanks to anyone that can help me some numbers.

I wont to bild one of thes http://www.decware.com/whornok.htm for a set of 8's will the RL-i8 work in this tipe of box and what will the sield chamber be it ses to model a regular 4th order single reflex box to determine the rear (sealed) chamber but i dont have the program to do this i know the rli-8 is not out yet but i can wate for it

I'm having trouble designing a box for the two Dreadnauts I'm getting in April. I don't know if I should have both of them in the same box or have two so they take up less space? I would like to have them in separate box's that are taller and narrow so I can still put stuff in the back of the suv. But when I try to look up the Recommended Enclosure I don't understand it. if someone could give me some pointers I would be thankful. I have never made a box before so this all new to me I will put all specs I have on the subs. Recommended Enclosure Vented (Net) Port Specs …

Ok, here is are 3 chioces of a mock-up for the install. I was able to raise my air tanks up high, and now I can fit a box underneath. Here are the 3 possible ways to mount the amps. None of these ways will they actually be attached to the box. I will weld some aluminum and stand them off a 0.25" or so. Mounting the amps on top, I like the most, but one amp is slightly shorter than the other... Mounting the amps on either side, and the RL-p in the middle..though, I dont like the M's facing opposite of each other.. Mounting the amps on one side, and the RL-p on the other... Taking a vote..without a poll I guess.. Got in all my wiring today, so just waiting on the soun…

Im in the process of a biulding a new setup which will consist of a 12in FI BL fully loaded with a Hifonics Brutus BRZ1700.1d. My last setup was a 12in FI Q with a Hifonics HFI1000.1d and i had a box i built myself that was 2.5 ft cubes tuned to 33hz with a 2.5 in slot port width. I had it in a chevy blazer and i could hear the air coming out of the box? How do i limit that noise so it sounds clearer? Vehicle: 2006 Nissan Altima Location:Trunk Space Available:30x18x15 Sub: 12in FI BL Music:Rap and Dubstep Goal: I want it to have the best SQ while doing well with SPL

Is it possible to to a T shaped slot port? I'm designing a box right now with 2 woofers and no divider. I was planning on making a L shaped slot port off to one side of the woofers, but got to thinking about putting the port in between the woofers and making it shaped like a T without a divider in the middle. No clue if this would work or if the velocity of the air coming from each side would create turbulence where they meet and make the port less efficient. I would put a divider in but I'm limited on space and a divider makes the port length longer per side and cause me to increase the size of the box to stay optimum and the dimensions are larger than I have to work wit…

OK, so I've decided to try out a box using round ports for my 18" nightshade, so i can make the ports interchangeable for comps and daily. I'm using a Hifonics Brutus 1600d amp. i figure the box should be about 5 cubes since the amp isn't that powerful and i want to get a lot of output. i want to use 2 6" diameter pieces of PVC. i am going to do some testing to figure out where my port should be tuned at for spl, but my question is that if i want to keep the box at 5 cubes how big should i make it to make sure its still 5 cubes after the displacement of the ports? i have been looking all night trying to figure this out. i found that if my box is 5 cubes i should use 2 6" …

I've been playing with a port calculator and I find that 30 1/8"x3/4"(which just happens to be my wall thickness) holes will tune the box to a nice 30.5Hz. Now, is there any reason for NOT doing this??? Thought I might arrange them in the shape of an SSA logo for effect.

Alright so i posted this on an other forum but no one really had any good insignt into what they think caused the tunning of my box become so high from what I tunned it to. Alright here where Im at this is what the box looks like inside its ruffly a little over 7sq ft each side , port is 17.5 inches tall and 6" wide lenght wise its 19" then it L's with the smaller side 8.5" for a total lenght of about 28". So i was thinking i was going to be tuned to about 34hz well after I got metered turns out im at 57hz any idea where I fucked up?

I'm wanting to know if I build a box like this and would it be ok with the ports like this. It would go in a 95 honda accord 9.67ft^3 gross, 7.34ft^3 after ports, after bracing somewhere between 7 and 6.5cubes after bracing, depends on if i invert it or not thanks for any suggestions or comments

Hey everyone I've been trying to mock up an enclosure for my truck in Sketch Up for 'bout a month now. I originally wanted to do 8 DC Sound Labs Level 3 12's. I really like DC audio and I have capabilities to get them at low costs. I wanted to do a 4th order but, I've been doing different designs and punching everything in to a 4th order calculator and using WinISD. I'm sorta stuck with ideas. Here's a rapid share of the usuable airspace and how the box would be shaped...a shell in a sense. mucho grasis, thank you, danke shon! http://rapidshare.com/files/184601903/blan...ge_perfect..skp I wanna stay using DC subs but I can change things around. I have a DD Z1 to pow…

Hey guys i'm building my first my box for three fi bl 12's and want to tune it to 31-33 and was wondering which would be better? Sealed,ported, or banpass?? Any suggestions would be helpful

okay so i just finished cutting and sanding all the pieces of MDF for the new box i'm building.. i used the re audio box calculator and it is gonna be tuned to 32hz. the only problem is that i am not entirely sure if the location of the sub will affect sound quality. just wanna play it safe and get some feedback. the specs are 30'' wide x 17.5'' deep x 14'' high. if the exact calculations are needed ill put em up. thanks

Gains will be set low (to start off, i realize hifonics isn't top of the line, but it'll do the job well even if it is overrated).. so any suggestions on a good wiring kit to buy?
