SPL & SQ / Fabrication

Do crx boxes work in a trunk with the subs up an ports faceing the back?

Knuconceptz 'Knucar' This guy might have an ssa membership, idk, but has anyone seen this? Everyone says 45 degree angles help airflow, so what would a perfectly round one do? It'd be near impossible to tune if you wanted to port, but if you could, would it actually work? Trust me, i'm not thinking of doing this because i can't make a sphere out of play-dough, just curiousity here.

i've posted this in other forums too, im just trying to get as much input as possible. this is for tc3000 12"dvc. several experienced people have recommended around 2 cu, but i've done some more reading and it seems that they recommended for SPL purposes, you want to use a large enclosure and port. But im not going all out SPL, i just want a REALLY LOUD daily setup, so im just going to experiment and try something in between. I've decided to go ahead and try 2.75 @ 33. i chose to use 15.5 sq in per cu ft since 15 and 16 seems to be the commonly recommended multiplier; the port area comes out to about 42.62 sq in. my max height is 13.5 so my width is about 3.157. i used th…

can the single of a L-ported box be divided into two? instead of one port on one side and the sub on the otherside, it will look like ports on both end of the box with the sub in the center? if its possible, is there a calculator online for that? thanks...

I am getting two Maw-15's and I was wanting to put them in a Ported Enclosure tuned to 30hz. But I drive a 1996 Ford Taurus and I'm worried I will come up a little short on Trunk Space. Any Ideas for the box Or do those subs sound good enough in a Sealed Enclosure? Thanks In Advance Guys. ~MadroX

Ok, so this weekend I plan on pulling out my box and putting the zcon's in. 2 12" 1 ohm z's goin in. Gettin the diehard platinum marine sat nite and puttin the saz2500 in. Rt now my box is 4.75^3. Its an angled box to fit behind the seats of my 3 door s-10. I have another 4" of room I can go up. That would be about another 1.4 cubic feet or so. Rt now the port is on the side and has about 78 inches of area. 19.5 wide by 4 tall. Is that enough or should I make it bigger while I have it out? Or should I leave it alone? Also what would be a good gauge of wire to run for the subs? I cannot wait to hear these z's rumble!!!!¡¡¡¡¡

Lets just say I'm building a ported box. And the port is 6"x13" (Round port) How far away should the end of the port be from any wall? For example, the port is on the front wall. How far does the end inside the box need to be from the back wall? I think i remember it being 1/2 the diameter, but i could be wrong. If anyone could help shed some light on this one, it would be a great help.

I checked their forum and it seems to have died off.

Has anyone ever used it? How does it work? Is it worth $17. I want to spray the inside and possibly outside of my sub box with it but I don't know if it is worth it. Should I just get some spray on bedliner in a can and use that instead? I was hoping it would created a better seal and add strength to the box.

Alright, I know how all you guys are happy to help people with set-ups and stuff. So I got one for ya. MY brother was paralyzed sometime around birth. So he is confined to a wheel-chair. He rides around in a big-honkin van. He loves car audio and has always been interested in what other people have. Anyway his birthday is coming up soon and I was wondering if you guys could just put your heads together and help me figure out how and where to put a system in his van. I will have pictures soon. Later Today. It's a '91 Chevy Van with the back seat cut out so he can drive his wheel-chair into it. Anyway I have to go put a water pump in. Thanks in advance for all your help and…

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.

07 toyota tacoma doublecab RE SL 10 Pioneer avic f700bt HU JL 6.5 components up fron and JL 6.5 coax in back Preferd matrial is mdf i've got a ton of it. But I am no strager to working with glass and dont mind it if will yield the best results. Im going for SQ im over the bckseat box thing. My goal is a very responsive package that will hit a wide variety of HZ. with ought ruining the sub or the amp. Have not purchased the amp yet but I am looking at Rockford Fosgate Punch P325.1 mono The space we're working with is tight Do I attempt to make an enclosure that will fit the exixting cavity in the starage area or do we pull it out and go for somthing bigger?

I would like to get a few different tones on a CD or something to play around with, where can I find some? Thanks, Mike B.

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…

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…

Hey quick question: if im looking for say 33hz from an areo port in a box 3 cubes how do i calculate it if i need two ports? heres the situation, i have box 3 cubes, want to run 4 inch ports. if i make one port its 7.4 inches long but i need more area than that.

Alright so iv made my box and everything and I would love to use body filler to smooth t all out and cover allscrew holes. I don't really want to spend any more money for this box... What's the cheapest way to obtain the perfect box?

I need help with a box design for a 15" Mach5Audio MAW sub. The recommended sealed box size for this sub is 62 litres (2.2 cu.ft.) 30hz tuning. I would like an enclosure designed exactly to these specs if possible. Thanks in advance!

Pic 1 this is the front of the box that will be facing the front seats Pic 2 this is a view of the back/underside of the box. Pic 3 This is a back/side view of where the 4" diameter aeroports will go Pic 4 this is the other side The sub will be downfiring towards the back of the cab at an angle and im curious of how this will sound. im thinking that since the ports will be loading off of the door as well as the sub it should be a pretty loud design but i would like some opinions since im new to box building. i wasnt able to insert the actual image

Hey everyone, been a member here ever since I bought my saz1500D last summer, and I Love it! been running it at 2 ohms to a pair of the older type r 12's in a sealed box since then. Around the time I bought the amp I got 2 of the new R 12's and now its come time to try and build a box for them, this is the first box I'll ever attempt so I dont really know how to get proper dimensions, ive tried the re calculator, but im still unsure if im right....so I figured I'd ask. but anyway vehicle is 98 gmc jimmy so space isnt a huge factor if need be, i can take some measurments of max size subs Type R 12 dual 4's x2 amp sundown saz1500D@ 1 ohm I'd like to have subs firing up slot…

Anyone know of any good Upstate NY Box builders, I was going to build my box myself but the Panel Saw that I was going to use is no longer available and I'm god awful with a circular saw. I'm in the Utica area to be specific willing to travel up to 1.5 hours for a good box, already have the designs courtesy of Alton. I'd also be open to out of state box builders but would have to be rather cheap due to the cost of shipping

So here's the deal. I have a Sundown 1200D, a Sundown 125.2 powering my setup. I will breeze over the 125.2 which will be hooked up to 2 sets of Polk db6501 components (2 ohm load) on each channel giving me a net of 100 watts to each speaker. I am building a CUSTOM box for a12" TC Sounds LMS-R sub. This sub can handle 1k watts continuos and 4k peak. I can wire this sub to be a 1 ohm load which is a load my 1200D can handle (giving out 1200 watts). I am trying to decide if I should port the box I am planning on building needs a port or not, and if so how long, size, ect I need it to be. I believe I correctly modeled the Treo TE sub I have now (in a ported probox) in t…

This is what happens when you get wood cut at home depot. I got all my cuts at home depot and some are 1/16 to short. they wasnt using the regular saw. i was wondering can i use some sealer tape for the cracks?

website specs say they like 2.5-2.75ft^3 do they like larger than 2.75 or should i keep it there?

I was wondering if the calculator here ; http://www.psp-inc.com/tools.html calculated it's tuning including displacement of the tube or without displacement. Thanks.
