SPL & SQ / Fabrication

Does anybody run bandpass boxes and if so, what subs are good to run in that type of enclosure? I quit running bandpass boxes awhile back because I thought they hold in wayyyy to much sound....

Ok I am getting ready to build my wall and was wondering what size bandpass box and port would be required for 3 solox 12's running off of 3 crunch GP3000dpros? Its going in a smaller car so that is why I am using 12's. tuning would be for everyday listening.

Does anyone know anything about designing a bandpass box. I have a pair of 12 w6s in a ported box w 2 6 inch areo ports tuned to 44 hz and a jl 1000/1. I can do 143.4 db at a 48-50 hz tone. Im trying to get in the uper 140s without reaching the 2500-4000 watt amplifier range. Any help on design principals or general advise on how to get louder would be greatly appreciated.

So, unfortunately i don't think i will be able to get the hight i need for 15s in a regular blow through. i have been looking in doing some sort of bandpass blow through with the chamber firing into the truck from the bed. i have read other posts and things but there seem to be too many different opinions and not facts. Any information for me would be greatly appreciated. I have seemed to be more focused of a 6th order. i like the way its ported inside a port but i do NOT have much knowledge on this so i'm looking forward to learning more about it. Would a bandpass be my best option, if so which one and why? i was looking to do something like this.

Aight guys, I have 10" american xfl sub a ported box tuned to 30hz in my sedan and I was thinking about switching it up and doing a 4th order bandpass box with a flared port tube shooting thru the rear deck. Also the rear deck will custom fiberglassed and molded to securely mount the port and speakers. Or should I just leave the ported box and fiberglass the rear deck with a vent for the bass to come thru. I'm just trying to eliminate having to keep the armrest down or having the seats folded down so that the bass isn't trapped in the trunk. Here's a video of a lexus with a 4th order bandpass box ported thru the rear deck thru the factory sub location http://www.caraudio.…

Ok I've been doing a lot of research on standard 6th order bandpass boxes, and haven't found enough information to decide if its better than standard ported for spl. If I tune a 6th order with a very narrow high output passband, such as 39hz rear and 44hz front, or in this general region, will it be louder than a ported box with a similar tuning? From what I've seen the 6th order will boost output higher, but it strains the subwoofer more and lowers power handling, so it has more output but you can put less power to it so they balance out... I want to try one out but if you guys think it wont be louder than just ported for spl use only then it's not worth trying. Also I…

just wanted to get some thoughts on bass box 6 pro..is it user friendly for a noob box builder like me and if so does n e one have it avail for a small fee

basiclly the lower i tune my box, it seems the higher DB i get on the graph. @32 =138 @26 = 139.4 @20 = 141 That can't be correct can it?

Any use this program to model stuff? If so, im too broke to pay for it

Where can I get Bassorcist tracks? I see people playing them all over youtube but I cannot find anything!

what is the best battery for street A. 650cubic in or less. from what ive found the nsb75 kinetik hc2000 and powermaster d2700 seem to be at the top. what bettery is the best and how much better is it than the others. if anyone knows of another incredible battery im missing let me know.

What is the minimum number of yellowtops needed to run a Sundown 3000d? I've still got the stock alternator in the Frontier and want to see what I can do. BTW the Opti 50C is up for sale.

I need some tips on doing a bed cut. This guy has 3 digital design 1500 12s. I cant remember the year or model but its a dodge single cab. The diminsions i got were 15" tall, 40" wide, and around 40" deep. He has them on a kicker zx 1000.1. I just need some tips on how i should go about doing this, since i have never done one before.

hey whats up guys i have seen on the internet and on a few forums people using bedliner as a sound deadener does it work and has anyone had any good or bad experiences from it

Sorry for all the questions lately, but i'm getting very close to having my box complete, and want everything to be right. So, has anyone used bed liner for their boxes? I really like the look of it, and i really dont like the look of carpet (it's allright i guess, it just seems like everyone has it). Does anyone have suggestions on what kind i should buy and maybe a lil info on how to apply it and make it look good? Thanks to everyone thats replied to my questions.

I just got done discussing with someone what i am doin with my wall in the car and have found a solution, a very cheap solution. I need to have my wall flared on the inside and outside to try and achieve higher pressure levels. My port area is 16.5" wide x 11.25" tall. Look at the bottom pic to see what a Bellmouth port looks like- for my application - There is a guy around town that can make me ANY custom size, flare, etc for my wall so i told him to hold off for a couple weeks while i test other things before i venture in flare port testing. I have some questions though so i can get him to make the proper size. The outside flare can stick out of the box a MAXIMUM of 5…

Im about to start building a tube out of MDF for a sub box, but before I needed to test things out to see if I could. I also decided to take pics of it for a little tutorial if other people are wondering how to do this. I started of by finding the inner diameter I need. Im going to use this for an 8" sub with a 7" cut out. so my inner diameter is 7" Now outer diameter: I'm using 3/4 MDF so my outer diameter is 1.5 + the inner diameter' 7+ 1.5=8.5" Now I can find out how long I need to cut my board: take the outer diameter multiply times pi to get the circumference, which will equal the board length: 8.5 * 3.14 = 26.7" Board length is 26.7" Now I need the inner circumfere…

Got a quick question. What does multiple runs of power cable front to back do? Does it increase voltage or help handle the amount of power being pulled from your rear battery back? I ask because I’ve had the fuse holder near the front battery melt a while back. Everything has been good for the past few months. And this just happened. So I cut off the melted part of the wire and put a new fuse holder in. And recently it’s done it again. Ive read that maybe the wire can’t handle the heat or whatever so it starts to melt. Will multiple runs of 1/0 awg help with this problem or would it be wise to just run a 2/0. My my system consists of a second battl…

Just wanted to share this incredible build with you guys. 83 pages and still not finished. Attention to every detail. BERYLLIUM BMW 323ci. - CARSOUND.COM Forum Some pics so you know what you are going to find in the thread: And many many more beautiful stuff. Enjoy.

I've had some crappy 12's (MTX RoadThunder) and a 500 watt Bazooka amp since I was 16. I just got a new job and wanna go big. I have a friend who has a DD 10" (2510 I think) hitting 139 db on music with 700 watts. Even though I have more money to work with, I need to keep it as cheap as possible. I really want a 15 and however many watts it takes to get loud as fuck without blowing the sub. -I was looking at FI Btl but its a little high -I know DD is good -I don't know anything about Incriminator. -people have mentioned RE the only ones of these I've seen in action is DD. This is not an SPL build, just a daily driver that I want to be louder than the crap I have now. …

I was wondering if you could send me the exact dimensions, that would be the best for the 12" BTL that I just bought from you tuned to 32HZ? The biggest size box that fits in the trunk of my Chrysler 300 is 32"wide by 35"long by 15"tall, that is the biggest size box that we can fit in there. If you could help me out that would be great.

Got a pair of MTX 8500 10"s that I am trying to sell (brand new in boxes still) but if they do not sell I am just going to use them. I am wondering what the best box style would be for a pair of these? I have pretty much unlimited space (Astro van) so that isn't an issue and they will be run on a XXX-6500D @ 2ohms so like 1500 each for burps, 700~ daily...

Alright, there has been a lot of discussion and I want your opinion! For an Integra, which is the best box for an all out SPL build? (and gets low) Wall behind the driver/passenger seatsSub up, port backSub up, port frontSub back, port backSub front, port front

Im new to building enclosures and would like to know the correct type/brand of screws and glue that i should be using. Thanks for the help!

Hey, this is what i got: 1x pioneer sub ts-w3002d4 @2ohms=1000rms QCA3500D amp; 2ohm=1750watts rms enclosure: 20"x16"x13" port size: 2"x11.5" everything on my car is stock and i think my amp is putting out a little less than what is rated performance wise, i dont think that my sub is performing like it should, my excursion is nothing compared to what I see on you tube and im not sure if it is because of my enclosure. I know that I can get better power if i upgrade wiring but I think I should be getting more out of what I already have. I want to try a different box, does anyone have any suggestions on sizez and I dont know much about tuning but im not getting high end …
