SPL & SQ / Fabrication

Pic of specs (or really close to, but hows the design, first ever, opinons, ideas, positive feeback.... will it work?? lol thanks guys!!

hello all i have a system installed thanks to the great guys at phoenix gold and its really fricking loud which attracts the hoodrats and hence, i have no window now. So i went to go get a new window and the thing is almost 700.00. so i looked at lexan and that is way frigging cheaper. so heres the deal. How in the hell do you install this crap. i know i am supposed to be able to cut it with a jigsaw and like sand it or something but i dont really know how or what techniques to use or anything else. i need to know how to put this in or someone that does it needs to do it for me but either way i need the big fatty lexan in there. Since there is literally nothing on this su…

Hey everyone. I am not sure what the policies are with box designs are here so i thought i would ask. If I asked for a design on the forum and someone does give me one do i pay them or what?? this is just a picture of the box. Like the dimensions of the pieces of wood. I could make the box but i have no clue on how to design a port or tune a box. If this was not clear or difficult to understand than let me know or just delete it , hha Thanks, Matt Cusack

Has anyone done one of these before ? I reciently picked up a eD e8a and I wanted to try it in one. I found a formula that seems fairly simple to follow. Build a box with 2 chambers, one at 3 cuft and the other one EXACTLY half of that, ie 1.5 cuft. Next cut 3 ports all IDENTICAL in length. Put one in the face of each chamber and the third in the wall separating the two chambers. In this instance each port would be either 12.5" long for a little deeper response or 8" long for a little more SPL. Now you have a box with a big chamber with a vent in it, a small chamber with a vent in it, and a third vent in the wall between the two. The woofer also mounts in the large chambe…

hey all been looking to make a t-line for a large scale project but wanted to start off with something small in case it doesn't turn out so well. now i no the port area has to be the same as the subs cone area, and the length is the speed of sound divided by the fs of the sub then divided again by four. but ive been told some have a common chamber and some don't and also im trying to figure out how to tune it or can you only tune it to the fs of the sub? any help would be greatly appreciated and ill let you guys know how it turns out once im done thanks mike E

So Im collecting parts to do a blowthrough in my fullsize chevy regular cab. 1988 k1500. Just bought a crescendo 3500. gonna get a singer 250a alt and a couple 3100s and one up front. multiple runs of 0. okay so now for my question. i have been pondering ideas on sub/box setups. I have been set on 2 18s for a while, but got to thinking about 4 15s. and idk whether to a 4th order or just a regular ported box. i can do the rregular box tuning but would need some help designing a 4th order as i have read and have yet to wrap my brain around it. My goals: Daily, Hairtricks (move air yo) not super low. 30-32 (in regular box tuning terms) not sure where that would be in a 4th o…

Whats up guys. I am going to try to build my own box. I have only built like 2 before, but I want to give it another try. I was wondering who can I Pay to design a box for me for 2 15" Type R's... If you are interested, or have worked with these before please let me know, or send me a PM.. Thanks. Steve-o

I started to build a new enclosure today. Gross interior is 12.5 X 53.5 X 7.5 bottom and 3.5 top, so 2.5 cubic feet gross. I am recessing the amp and the panel is 22.5 X 13.5 X .75 sunk 1.5 into the enclosure. There are (4) 1 X 2 X 55 and (4) 1 X 2 X 12.5 to account for and the displacement of the sub (RL-P) I think is .18. I want to tune this thing as low as possible (28-32 Hz) so dual 3" ports probably. How long do I make them?

I'm well aware of the complexity (or so it might seem for some) involved in creating a ported enclosure built to specs. I'm also aware of situations where different subs have been dropped right in to a ported box previously housing another sub and working well. With that being the case I was wondering how bad a prefab box like this one I stumbled across on ebay could possibly be. I'm absolutely prepaired to pay for a properly made custom box but was just curious a) if anyones had any experience and b) if this is just a COMPLETELY bad idea. Heres the link to a prefab 4 cu ft ported box tuned to 32 hz (almost exactly what I'd be getting custom made): 15" CUSTOM-PORTED MDF S…

If i use a flared areo port in a 2.5^3ft box would one four inch be alright that would be 12.5 square inches port area. Box will be for 4 8" subs

alrighhtttyy guys.... i got a different build that i need some help with because i realized the two SPL15s had a slim chance of working out =[. I'm putting a ascendant audio mayhem 18" in the trunk of a 01 chrysler sebring sedan. The sub is going to be front firing and im just going to keep the back seats down (when i put them up for people to sit in them i will just cut the subs off). The trunk is pretty flat and the box should be pretty easy to load in from the car with the seats folded down. I have L29 x W34 x H18 to work with. for you who dont know a mayhem is essentially a loaded BTL.

I have 2 Assassin Series 8's I need to know how to make the port and how big. The box I have a pre made it is this http://www.millionbuy.com/hbx8antcm.html its .51 cubic feet any help would be great

Planing on tuning it to almost 42 hz. This will be a competition box for my 04 jeep liberty. Subs up port back left. My question is what type of sq foot should i use for this box. Alpine's site says use around 2.5^2 per sub in a ported enclosure. Also if it matters im planning on running these off of a Sundown SAZ 2500d

Are there any SQ comps that are regularly in NC? I see that a lot of you SQ guys are from VA, where do you usually compete? Any local organizations or the like? I have never competed before, so I would appreciate it if someone could point me in the right direction. While I'm at it, what are the different SQ classes, and their requirements?

what type box would you suggest for a sq setup i know the norm is sealed but i've heard a few ported boxes and they sound pretty nice give me some of the pros and cons of both btw subs being looked at are idqv2 12" IA LI 12" and SA-12 thanks for any heip provided

I want to check some numbers but Im not sure if there are any trustworthy sites.. Got any?

i am trying to build a box for 4 of my kicker cvx 15's. i called kicker and they recommending using separate 3.5 cub. ft chambers tuned to 38 hz. since this is gonna be my first box build is there an easier less way to build the box without having 4 separate chambers? maybe 2 subs per port or all 4 with one port. it is going inside the car. maybe even a wall design. my available space is 32x56x36.

Okay so, I got my designs, and lowes completly messed up all the cuts, so I have to take it back and complain and hope that they give me new wood or something..... So in the meantime, I just "sketched" up this box. Here is a pic here is the google sketchup file http://files.filefront.com/fibtl18skp/;13080625;/fileinfo.html for anyone who wants it Let me know what you all think! (I didn't make up the specs for this, a help from another member on this site did, I just drew it)

Anyone have the meca world finals results? Just curious on how our shop vehicles would compare..

This will be my first show in over 2 years by this time! Last event I was in was the 2002 SLAP Finals where I was 4th. My system isn't designed for dB Drag so I will be outclassed a bit, but it will be fun to get into the lanes again. Here is the link to the show if anyone cares:) http://www.termpro.com/asp/members2.asp?Who=13&MemberID=6498

ALright, I'm getting to the point of install. I am curious about the whole gain knob deal. I have always just turned it up to where it sounded good, and went on. I remember reading something about matching low level volts? So, anyway, my headunit is a whopping 2volts. - that goes to my Phoenix Gold EQ, which has a built in line driver, adjustable from 1 to 8 volts. Then, back at my Memphis amps, they are able to recieve between 1 and 4 volts. SO..gimmie a run down on how to get this stuff adjusted properly..or is there a link that could tell me and save somebody the typing?

I own the following items: http://www.kaptionaudio.com/manuals/SPLManual.pdf ( I have the 15 inch) http://www.kaptionaudio.com/manuals/KaptionD-Class.pdf (biggest amp they make) I am trying to build a loud, clean system. The dimensions and information are in the pdf for the sub. Now, I listen mostly to rap, some rock but mostly rap and otherwise a mixed back. I believe sealed is the way to go because I like the clean, clear bass... I will be leaving in the third row of seating in, but have it flipped up (or maybe I should take it out). I need to use the space above the sub for the transfer of some goods etc... Should I center the sub, put it towards the rear seats or t…

ok, so im about to start a T-line enclosure for a single 10" and im wondering if i should bother doing a double baffle, or even just double thick mounting plate. the line is only 5 inches wide and 11" tall, so its naturally pretty well braced, and it will probably only be seeing somewhere between 250 and 400 watts. so will a double baffle really help? if not, do you think that i should use a mounting plate to give the screws more wood to bite into? thanks for any input
