SPL & SQ / Fabrication

i had a thread a while ago that had a download to a box tuning calculator that i made. i've since upgraded it hardcore and would like to repost it. i cant edit my original post in the other thread which is why i'm making a new one. also since i cant edit my original post to update it, i'm linking it to SMD where the original thread is to download from. that way i can update that one which will in turn update the link to the download from here and still allow comments and questions on this forum (i hope that's all ok). if a mod would like, the other thread can be deleted if they find it to prevent any confusion. that one is pretty old tho, so probably buried tho i found it…

i got a kicker l7 15 dual 4 wired to 2ohms into a hifonics brutus 1200. i just got my box built by one of my buddies who owns a shop. the box is roughly 5 cubes tuned to about 35hz pretty sure. i got everything together last night and spent all day today playing around and trying to tune it and it just does not want to put out those real lows in some songs. sounds like its just blowing air. None the less it tears apart the mid to high bass. i dont know what i could do to change it up maybe rebuild the port or something. not to good with this stuff thats why im asking you guys. inside of box dimensions: width 39 height 13.5 depth 18.5 its got 3 in wide slot port its just…

Okay, So to find out what Hz my car peaks at, do I try out different test tones to see which one is the loudest in my car? If so, then what do I do from there? Say my car peaks at 37hz...do I tuned my port to 37hz? Reason asking is because I built a 2.5cuft. net @ 32hz enclosure with a 4" aeroport. I can take it out and cut it down for SPL. I just want to do it right since I only have one tube insert left. I'm aiming for SPL, not a fartbox. Thanks!

I ordered my First 18in. btl on tuesday and i am ordering my second on friday. In anticipation I got to playing around with some designs. I am going with a wall build in my trailblazer and i got the front template all cut out perfectly today and threw it into sketchup. Double baffled 3/4in. mdf on the front and double baffle all around for the actual enclosure also " even though it is not shown in sketchup" After sub displacement it sits at 21.07cf. and no i am not counting the sub braces since i just put those in to see how i would set them since i dont have the actual subs yet. also i will be throwing in a couple of 45's to help so am i missing anything big/gettin…

BEFORE AFTER! do you like it?

So I only have bought pre fabbed boxes... Yes I know I am a lame person. The boxes are probably not to spec. And the boxes I usually get are cheap and are usually sealed. So I have been doing a lot of research and I think that the next box I want to BUILD is going to be a ported box. I know this scares me because of how hard it is going to be but I think I can handle it... If not it is a learning process. I am getting a Icon 12 dual 2ohm sub. My uncle who lives here does flooring and has tools/experience with wood working and stuff. Also what he does have experience with is fiberglassing and also doing carbon fiber in the hull inside his jet ski to make it stronger. I …

Hey guys, got a huge favor to ask, i'm doing my first build for a customer, for a neighbor, for an Icon 15d2 in about 4cubes @ 28hz forward firing in a 01 deville What should I shoot for for port area, and have any of you done forward firing setups in a deville before? I'm tryna make a good impression lol. We're going to carpet it to match the trunk for a stealthy look, well, as stealthy as a ported fifteen can be lol. It'll fire through the ski pass. I guess I'm super anxious about it since building for yourself you never have to worry about an upset customer, you just rebuild. Thanks in advance. Edit: It's for a blend of all types of music, and the mids and highs are t…

i finished putting this togethre right now... LMK what you think. I'm uneasy about the tuning freq because i was unfamiliar with the calc. i used. since the box is wider, i can now have a good 26" of port area. anything wrong with what you see? the sub itself is .3 cubic ft but i will add more baffle to compensate

i need to finish out the boxx and wall off the open side where the batterys go

I cannot decide on what to do. 4 SA-15"s in a standard ported wall, or 4 SA-15"s in a 4th order bandpass. What are the positives and negatives of both? I've helped build a 4 15"s wall in the 60's and an 8 12"s 4th in 60's. I like them both, both sound good, both played well. I just cannot decide on what type of enclosure to build.

This is my most recent sub enclosure, I designed and painted it. Looks way better in person too. Tell me what you guys think of it. Thanks.

Just found out my old Eagle Talon holds the record in Stock 2 class in IASCA. Hmmm, How come I couldn't do that with the car? LOL. After several owners and some modificatins it is now loud!

Ok, I got my first 15" sub today. All I've ever dealt with before are 10's and 12's. At the moment I have a pair of 12's in the back of my 97 Grand am, each one seeing 1.25 cubes sealed. The box is easy to work with, I can have the whole thing pulled out in a matter of minutes. I would like to have something similar with this 15. One problem....the clearance through the backseat is only 13.5 inches, I believe. The space to go in through the back isn't very easy to work with either. If I build a box that has the sub laying on it's back with the cone up, I really think I'll lose a lot of the potential from the sub that I would normally get from rear-firing it. Also, I …

think this is a good stasrt for a moderate sq set up i have a kenwood 6019 indash focal 165 6.5 v2 pollyglass componants focal 6.5 pollyglass 2 way coax. kicker zx1000.1 kicker 350.4 an 2 re se 12's subs. im thinking of swaping amps out to something more powerful but is this a good start?

just like to say that my little boy will be in the lanes this year. he's 5 yrs old and going to compete in the mini SPL cars. so hopefully we'll be finish with it in about a month or so. wish him luck jamie
