SPL & SQ / Fabrication

I bought a x12 and have made the reccomended ported box for it. I def sounds amazing when the windows are down in my truck it gets really low. But its not really as loud as i want and most of my music just dosnt go that low.. The other thing is i have a pair of harrison soundlab external subsonic filters... And a pair of right angle adapters from radioshack.. Could these be lowering the signal to the amp and decreasing my out put? Any help would be great. Iv heard you can fill the box a little to raise the tuning frequency.. Idk the sf are at 30hzbtw

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…

I only get static when both sets of rca's are plugged into my 4 channel avionix amp. When i have ony 1 set of rca in the amp it is clear (Static-free). I tested this on both sides of the amp and the same thing happens regardless if i have the rear rca installed or front rca installed or vice versa. ANy ideas?

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.

I just got a 12" Mag from Low-Hz, and currently have it in my old sealed box that housed a JL 12w6(v1). That box has about 0.8 cubic ft. after driver displacement. Anyway, I was planning on building a ported box and got this off the net: http://www.subwoofertools.com/forum/ported...=&Vas=&Fs=&CE=0 I was all set on building it, but decided to read more, and the more I read, the more I get confused and hesitant. So I decided to ask the official SI site for input. I want the best ported box with a maximum width of 30" and max height of 13". It's going into a 95 Ford Mustang, and I would like the box to fit perfectly into the hole when you fold down the seats. …

i have a 92 s10 blazer and i want to put a single 15" sundown d2 and i want to build a spl box but i will use this as a daily driver does anyone have blueprints or pics of any boxes for this setup?

ok XTRemeasures, I think i'll deff be down next weekend for this event you where talking about, could you post up the details for me, and i'll call ya when I get there. thanks in advnace. Also, who else is gonna be in attendence?

Long story short, Everything is brand new. I have a 12 RE Sex that I built in a sealed box. The box was to big after I was done (1.66) so I packed the back wall with 2x4. Well after I had installed everything I had local shop try to tune the sub. They agreed it was missing the low and just had no balls. They suggested we use the same box and port it. Re specs for min port box is 1.5@35Hz. They said we could use the same box as it is 1.66 and they ported it using 3 inch pvc tube that was 7 inches long. It was night and day but I would like to get others opinions since I have put a lot of time and effort into redoing my entire audio setup. Here is my setup: Truck: 05 Ford F…

I am building an enclosure for my truck today. I will have 2.5^3 net before port behind my rear seat. I have a few different options available. I have a Rockford T1500.1 bd CP for power. I have already 6 Rockford P2 8"s, my plan was to do 4 ported. Would end up .5 each after port and all with a single 4" Aero Port. Would tune it around 29Hz Thoughts? Ideas?

If I drill a whole just big enough for the speaker wire to pass through what should I use to seal up the whole so no air leaks out? Thanks

Hello This is my first post here, I made a quick look ,it's interesting forum. However I want to ask about the specs of the SQ system and components? I have Car PC controlling my sound system which is: Car PC with Turtle beach and Creative Xmod USB sound cards. Rear - Infinity Reference 9613i 6"x9" 3-way car speakers Front - Infinity Kappa 63.7i 6-1/2" 3-way car speakers Amp - JBL CS60.4 4 Ch 240 Watt Full Range Amplifier what do I need to add/change to have SQ system? thanks

I have 1 06 Kicker L715 in a ported box in a 2004 Isuzu Rodeo. Im gonna build a new box first the measurments are Build the enclosure to internally measure 5.0 cubic feet. Use a port opening that measures 50 square inches (3" X 16") and a port length that measures 15" deep into the enclosure. Im looking for a little sq but mostly spl. Its goona be tuned to 33hz. Is that good for what im looking for. My amp is a KX1200.1 and its wired down to 1 ohm. Thanks for any input

Still doing my Thunderbird blowthrough build with the 2-12"BTLs but Im already looking ahead of what I can upgrade to. I know what I wanna do (no Im not telling). Soooooo I want some opinions on a enclosure I thought up. The question is really about the direction of the port. The box will be a half L and half T shape.....(removing rear seats) part of it would be in the trunk but most of the box is in the cabin. so the subs would be facing up with the port forward. reason why I want the subs up is so I can use some plexi. It'll be just above shoulder level. Leveled with the rear deck. This is what Ive drawn up. Do u think the port will be fine facing forward? note this is …

i have i box that i need to find out what it's volume is and what it is tuned at. it is made of 3/4" mdf and has a double baffle. outside dimensions are: H 23 1/4" W 20" D 45" inside port dimensions are: H 5" W 18 1/2" D this i am not sure which measurement i need if i measure from the face of the port to the back wall it is 44 1/4" deep if i am to measure the length of the wall which divides the box to form the port it is 38 3/4" deep there is a 45% in the back of the port. thanks in advance for the help. would like to learn how to do these calculations also. perhaps if some one had the extra time i would love to see it drafted up into…

In the process of designing a box for the 15 Loaded BTL. Can I design an "L" slot port box to have a tuning freq of approx 40hz for comps...and then just put 1.5" thich MDF along one side of the port? Since calc's tell me that will bring me down to 32hz. So the port will be approx 6.5 inches wide for a 40hz tune and 5 inches wide for a 32hz. I'm just wondering because only the last 14inches or so will be 5 inches...the other 14ish inches (inside the box) will still be 6.5 inches. Will this screw with tuning...and will this raise or lower my ACTUAL tuning freq?

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

Many times I have been asked: "What if I don't have a table saw, how can i still make a good box?" This video answers that question. Enjoy!

just like it says if someone has experience with a 72' bug and or a BTL 18 I am looking to redo my box and need design help. Please PM me on here. I just know I can get louder than 144 with a exile 2400.1 and a standard BTL with cooling. Thankx MC

Ok this box will be for a customer of mine and i cannot find a damb thing about these woofers.. personally i dont like PT products but if you got money imma build it.. lol so im thinging 4.5cubes 63sqin of port and tunned to like 36hrz sound good smaller bigger let me know

I am putting together a box for a single 12" xcon. It will net 2.7 ft^3 and be tuned to 30hz. My question is: how much difference will lining the inside of the box with resin make? Is it worth the extra time and money? This is a daily setup, I do not compete. Will my ears b able to tell the difference?

What has been your favorite show you have attended, not necessarily competed in? I would say the best show (besides SBN) would be the first show at Ft. Drum, NY back in July of '00. It was a smaller IASCA show hosted by Terry Floyd. There were maybe 25 or so SPL cars and about 10 or so SQ cars. I met a lot of people at that show that wound up being good friends. Highlights from the show. I had the high SPL for the day at 151.0 I caught my car on fire! 2 of my other buddy;s got 1st in their respected SQ classes Here is a buddy's truck that won one of the pro classes. He went on to IASCA Finals that year. Real sweet truck.

Can I mount the subwoofer in the port, like this? And... Would a 12"Height 1"Wide 6"Deep port be the same as a 6"Height 2"Wide 6"Deep port? Would it sound any different?

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

This will be my first wall build, I've been doing a lot of reading and looking at build logs. I should start by saying the plan is 2-3 (if I can fit 3) RE XXX 15's, on either a DC Audio 12k or Stetsom 14K. I think I'm going to go with Baltic Birch for weight and strength, I am seeing guys using 2 by 4 bracing, also seeing them use it for the back of the wall outside, what is the purpose? is it needed? what other ways would you strengthen the wall or face? the subs weigh 76lbs a piece. I was thinking 3-4 layer front face, double layer everywhere else, fully resin the box. How much bracing would you recommend? If you have pics or anything else you might recommend I'm open …

I'm trying to figure out an enclosure configuration for 3 SA-10s, just not sure which way to go. Was looking at doing a downfire enclosure with an aeroport(s) firing to the side,. Just curious if there is any drawbacks to something like this. I like the idea of it being less visible, as well being a little more protected from the elements if the top is down. If it's a terrible idea, I'm all ears for better options. Thanks
