SPL & SQ / Fabrication

ok so my bro has a 15" l7.... seems to be alot of these mentioned in the forum lol. right now its in a sealed 1.5 cube box. a kenwood kac something something powering it with 900rms. car is a mercury sable with the mach audio system. currently the amp is using a loc to get single but my bro will be geting a mtx req or similar device later this year. theres no deading in the car and it rattles like crazy as is.... sorry to anyone who has heard and affended by the rattle... hes geting like 2 rolls of raammat for xmas from my parents we picked up some mdf and liquid nail today and plan to do a new box for the sub. im hoping to do a ported box with a pretty spl oriented de…

Looking for a box design for my 12" GCON. Can anyone point me in the right direction? Any help will be greatly appreciated.

Right now, Im running an audioque hdc3 12 in a 2.2 cubic ft box ported at 30 hz. Im losing alot of sound quality with this box and I was wondering if there are any specific box types (other than sealed) in which I may be able to retain a bit more quality. Im aware that the hdc3 is known for poor sound quality but Id rather not purchase a new driver at this time. I know anybody could tell me that it varies from car to car or something general like that but Im just looking for anyone with some experience who may be able to help me out. Open to any suggestions! Thanks

Hey fellas, After being away for a while from the car audio scene, a friends prototype actually grabbed my attention and I decided to get one. The only downside to this is it is super long (around 17 inches). If any of you guys remember CoDrive, then you know pretty much about this sub. For those of you who do not, it is a double motor, double vc design for one sub. It uses 10" spiders, custom machined sundown motors for 8 layer flat wound 3" voicecoils. This beast will have a good amount of excursion and kill the lows. With that said, it will weigh in at about 100lbs (doh). I was looking at designs, messing around with some myself, playing with bbp (that thing doesn't l…

Has anyone put a xcon in a 4th order? If so how did it sound will the sq be just ass good?

So Ive got what looked like a decent box on paper (BBP6) but once built is quite depressing and seems to be choking the sub. It sounds decent but just leaves the thought that so much more could be gotten from it, but Im not all that great with designing boxes, every now and then a good one pops up. Another member gave me the idea to build the box in a way that the sub would angle some to fire more towards the rear glass and have the port fire back, if anyone is willing to toss in some input or maybe help with a design that would be greatly appreciated. Space to work with is 17.5" tall, 24" deep, and if possible 28" wide but could get up to 36" wide if I relocate the spare…

Ok well I'm building my new box for one SA-12 it's gonna be 2.48 cu. before port and sub displacement.I'm gonna use one 4" aeroport.It's gonna be sub back port side going in a trunk car tell me what ya'll think?

So, i am HOPING this is the final box design for my SPL-15 as I am going ot buy some MDF here in a couple hours. HOWEVER i just thought since this is my very first box design done by myself I would throw it up here for you'all to check out and let me know what you think. Nothing Fancy, just a simple ported box....

I've got a 2.4 cube box tuned to 30 hz with a 3" aero port. The sub is a Fi Bl 12 getting about 750 watts off a Powerbass ASA1500.1. I went to comp last sunday and did a 136.8 at 44hz. If I made the port tuned to 35 hz, or even 38 hz, would my score go up? I'm not too worried about the competition in my class since I am sitting in 2nd place in the circuit, but it's always nice to be louder.

If I do my setup the way I'm thinkin, looks like I can only fit tens. Max diemensions is 34 w X 15 h, I'm pretty certain. I've got the rest of my truck bed in regards to length. I've got a few ideas.. Lemme explain this. First off, these are overhead view of how the box would be. There not to spec or anything, just some ideas. Its not the right diemensions or anythin.. just some ideas how I could fit a few 10s. Would fire into my window. The first one, top left, is a sealed box, kinda based on a clamshell on its side. second one has four subs, and a port in the middle. Bottom is just a ported box with two tens firing into the window (not sure if you could fit two tens an…

Looking for some help with an enclosure for a 15" xcon... I could go sealed but I need the help of you gurus to figure out how to get it ported Currently I have the Xcon in an enclosure that is roughly: 32" w x 17" h x 15" deep ... I have a 2016 Mazda3 hatch. My max dimensions for depth is 19.5" but that's only keeping a flat wall, I'm wondering what can be done about having the enclosure sort of follow the back of seats at the present angle. Like so but less aggressive of an angle obviously...: So my hopes for the enclosure are: 1. Ported - 6" PSP port 2. Max dimesnions would be W-26" H-20" D1(top side)-19" D2(bottom side)- about 2…

I have a number of questions that I was hoping someone with experience can answer. I'm currently running a 15" BTL off 1600 in a 4 cube enclosure at 33hz. I feel like I don't have enough port area- i'm using one 6" aero which gives me 28" of port and 7" per cube. Do you think i'd have a noticeable difference by switching to a larger 8" port? I already bought the port, but don't want to destoy my old box if there wont' even be a noticeable difference. I'm hoping to achieve better lows...I figure that my larger port will give more output/peak at my tuning frequency of 33hz, hence giving me a better low end. In doing so, i'll also gain slightly more volume in my box (…

I've had this sub for about a year and I want to build a new box for it. The first time, I built the port a little small (port area wise), so this time I'm going to make it bigger as well as increase the box volume. My plan is to make a box that is 32" wide, 22" tall, and 28" deep with a port that will be 20.5" tall, 6" wide and 35.6" deep. According to bassbox pro, that will give me a 29hz tuning. Does this sound right? Those are the maximum dimensions I can fit in the back of my Jeep while still keeping the port about 5-6" away from the hatch. Any suggestions? BTW, it'll be sub up, port back and it's powered off of a sundown SAZ-1000d. Also, do you think I'll need a…

if you got a question just ask more than happy to help and if i can't i find the answer for you

So i've read on numerous threads that the RE box calculator tunes a tad bit high. Personally, i'm a noob when it comes to making boxes so this RE calculator is just a great tool!! I use it mixed with Win Isd to make my box! i just really wish win isd had a slot port option So for people like me, and many other box designing noobs the RE calculator is awesome!! Its free, easy to use, you can see what changing port dimensions do to your tuning. So, does the Re calculator ALWAYS tune high? is it the same everytime? I'm curious because i'm desiging, or trying to, a box for my friend for his first gen 15" icon which i purchased for him. Also, on a side note, when designing…

Hey! I´m new here Just ordered a Warden 18 2x2 ohms thats going to sit in my SAAB 9000 coupé in the trunk. It will get about 4500 rms from a Soundstream Goliath Tarantula XXX 6500D. How big box do I need? I want to play loud (ofc) but loud to music, not to pure sinewaves. The music I´m playing is Lil Jon, Ludacris, Young Jeezy... that kind so tuned to 30 hz would be really nice Depending on what the FS is. Cant find it *If I´m spelling something wrong its because I´m Swedish *

Ok,so far a lot of testing and tweaking I cannot get my 187s to sound right or get nearly as loud as two 15s should. So I am doing a swap out, I have narrowed it down to 2-3 subs. The Fi BL d1 12, the DC sound labs level 3 D1 or this is a huge "maybe" I was recommended to try the lanzar opti drive 12..........? just trying to get some feedback and if anyone has personally used/tested any of these subs going to run it off my AQ 1200d

alright calm down.. i know the SQ guys are all worked up with sand in thair clams right about now.... i want better sound in my car.. i have some highs and mids but not enough.. i wanna get a cleaner sound. i have 2 bl 15's on a saz 3000d. and then i have 2 sets of 5x7 alpine typr R comps in the doors and in the rear deck. it sounds good at mid to low volume, but when i turn it up to higher volumes the tweeters are steal sounding and the word are ran over a bit by the subs.. its not THAT bad.. if you watch some of my vids you can see that some songs are better then others ...... some sound good.. and then other songs are just blah... i know 5x7s are junk..…

I have 4 DP21"s and 2 SAZ-3000d's that I'm stuffing in my 03 Expedition. I'm looking for ways to get enough port area with the subs...The box will be at the B-pillars sealed from the back. It will be about 40 cubes tuned to between 30 and 32 hz. So I'm wandering if I could port through the diamond itself without any problems. Or would this be bad?...Any other ways to get sufficient port area would be appreciated also.

hello ssa and people with grand prixs lol. i wanna but a 15 fi bl in the trunk of my 97 gp. but idk how i can make a big enough box but still fit in in through the trunk. people with gbs can i get some box dimentions please that would be great. thanks for veiwing.

skip to about 9:30 to see them take apart the speaker box, or watch the entire video if you want a good laugh. I've never seen anything like this in my life. And I thought the chevelle that Meade fixed was bad LOL it does not compare to this http://www.youtube.com/watch?v=AKH23bamIKU

Just purchased a couple of eclipse 88120s in a custom enclosure. I threw it in today and, similar to my hdc3, I am lacking in low end output. The box is dual chambered,tuned to 34 hz, and each driver has about 1.6 cubes. I thought that I did not need to build a new box because the tuning of 34 hz is low enough to achieve the lows Im looking for. However, like i previously stated, Im lacking low end output. It seems like Im never going to be able to get the flat response Im looking for. Thanks for the help guys! edit: The custom enclosure has two seperate ports, one for each driver. I could remove the divider between the two ports if that would help. But, as far as I know…
