SPL & SQ / Fabrication

I have one, and I believe the knob is dead, the light does not come on and I cannot control the unit from it, I dont want to send it into PG and have to pay 100 just for them to look at it, any ideas? or Dave could you take a look at it?

I just purchased a used 2007 Lexus ES350 which has a factory 10" subwoofer on the rear deck. It accomplishes some midbass, but just doesn't fill the cabin like I'd hoped. I want to install a Sundown SA-12 along with my existing Rockford 1000bd (I won't have it turned all the way up most likely). While I realize the RF Amp probably isn't best at a SQ install, I'm hoping the Sundown can fit the bill. My question is: Is it possible to make a box that can fire through the fold down armrest in the rear seat or up through the deck? How complex would something like this be in order to eliminate the loss or sludgy sound of bass firing into the trunk? My main reason is to try and…

Alright so i posted this on an other forum but no one really had any good insignt into what they think caused the tunning of my box become so high from what I tunned it to. Alright here where Im at this is what the box looks like inside its ruffly a little over 7sq ft each side , port is 17.5 inches tall and 6" wide lenght wise its 19" then it L's with the smaller side 8.5" for a total lenght of about 28". So i was thinking i was going to be tuned to about 34hz well after I got metered turns out im at 57hz any idea where I fucked up?

I might be doing an install with a clarion DRZ9255 with a active setup on the HAT L1's .. wondering how accurate the built in crossover is on the clarion if anyone here has used it in this fashion

can someone help me, im going to home deopt today, need some dimensions. can anyone help, i would greatly appreciate it

What are the advantages and downfalls of fabricating the vehicle below for a SPL vehicle. http://www.we-todd-did-racing.com/browse/g...oud/51586_mp6d9 Playing with the idea and would like some feedback. Much appreciated.

I am planning a box design in which I am using two 3" aero ports. The ports are supposed to be 7 inches long. My question is when using aero ports does the actual tube have to be seven inches or does the entire port assembly (flares included) need to be 7 inches?

Hello , I am building a box with a round port. I'll try to flare the openings to have a nice flare port It will be a 6" port or an 8", I don't know yet ! How far from the box side can I have the port ? How much "room" does it need to play correctly, safely ? I know I can use an elbow, and I will if it's necessary. Thanks in advance for your advices.

Hey everyone, i have 2 T10001's powering 4 15" cvr's and im looking into a more reliable subwoofer that will belt out the lows a little bit better. I have narrowed it down to 2 18" Bl's with the cooling option(as i heard its neccesary) Question... i have 46L 27T and 19D to work with, however i must put a divider in because i will be running 2 amps, 1 per woofer(i dont want to blow one due to mechanical errors) So if i cut that in half i get 4.679 cubes with the port 22.25x2.75 per chamber. 35hz 4.679 without woofer displacement. Is this giong to be sufficient enough because i know it says 5-10 cubes for this woofer. Im really looking to keep the same output as my cvrs bu…

I Recently Talked to Chad Kyupers Drivers Start Shipping a week from today. While talking to him i mentioned 6cuft@29Hz, he said he had a guy do 4.5 at 30Hz and its output was INSANE with only 800w. he said 6@29 with 1200w should wang hard so im down to 2 enclosure options, both with equal port area (77sqin) only one iwth 2 ports and one with one. originally i though there was going to be no way to get the ports on the same plain as the driver, so i designed a side firing enclosure and the port a straight shot. then i came up with the idea to get the port on the same plain... see image below http://i11.photobucket.com/albums/a167/CBFryman2/avatest.bmp the bottom thing…

Just a for instance: Say you have an enclosure 40" wide x 32" long x 30" high, The port is 38.5" wide (facing forward), 6.5" in height, and 24.5" in length - tuned to approximately 34Hz (I'm assuming a driver XMax of 20mm.) The Net enclosure volume is 14.40 cubes, less driver displacement. You have the option of placing (4) 15" subs on the top baffle, or (9) 10" subs. Which do YOU choose, and why? What subs would YOU do? Roughly 1.5 cubes each for the 10's, or 3.37 for the 15's. Either way, it would be possible to run whatever amp at 1 ohm Mono - Strapped SAZ3500's, anyone? I'd be VERY interested to see/hear/speculate what the XCONS would do......

i need a box build for my sa-10's

ok my friend will build me a box in his wood shop but i need to get him plans. SI 15 MAG, ported. what do you think of the aeroports? is it worth it for only $25 extra? most people use 2 of them at $12 each. power will be a hifonics ZEUS 1000D 1000@1ohm it is a lexus 2002 es300. should be the same as the new camrey. people have put 2 15 in there before with a almsot bent box. i only need 1. the red strap is what i will be using to hold the sub in place, i would also love there to be ehough room to put my trunk battey next to the box. it is 6.5 inches wide demetions are THANKS FOR ALL THE HELP I AM FINALLY BUYING A SUB TO FINISH MY AUDIO SYSTEM AFTER 2 YEARS!!!!!

I posted under another topic but calculated the wrong numbers so here is the updated version. The other post topic is misleading so that is why i posted a second time. This should answer any questions of why i posted another topic. I apologize Admin. This link shows the design outline: http://s883.photobuc...re.jpg#comments Here are the numbers: Wedge Enclosure Width: 43" Height: 27" Top Depth: 8" Bottom Depth: 20" Total Volume: 7.885 cb.ft. Port (32Hz) Internal: 20.0"H X 4.0"W X 24"L External: 20.75"H X 4.75"W X 24"L Port Displacement: 1.3689 cu.ft. Woofer Displacement: 0.38 cu.ft. (2 Fi Q 15s) Bracing Displacement: 0.1255 cu.ft. Net Volume: 7.885 - 1.3689 - 0.38 - 0.12…

Has anybody had any experience with Rear-Firing in Single Cab? I plan on doing this or downfiring. The only problem with downfiring is the max bottom depth I can do is 12.5" so the 12" sub will be on the surface of the wood just barely. I'm worried it might not be enough support because that will leave about 1/2" on both sides of the Sub Hole. (Where ever the sub will be, it will at least have 2 baffles.)

Just finished an install on my 95 probe. Put a DD 3515 in 3.5 cubic foot (after displacement) box with 2 - 4" aeroports at 17.75". Hooked to a RF 1000a2. Box is a standard CRX design. I've been toying with box placement and right now its sub up port to the side. Sounds decent, but a friend had this exact setup in his 98 Explorer and it was quite a bit better in there. So I'm assuming the problem is related to box design, tuning or placement. Any suggestions??

what tunning should i use for my box , i need it for LSQ should i do, 25-30-35 or 40 ??

I have been searching around now for a good 30 minutes on how to figure out the bass in a song. I know you use some program and play the song through it. You then select a little bit of the audio stream and analyze it somehow and it will show how low the bass gets... (I am trying to figure out the bass line in song. When it drops to the second lowest, I have never heard my car rattle so much nor my woofer get so loud. The first bass "hit" is at 34.5 seconds. And the bass hit at 37.5 seconds I need to filter out. I see the speaker move for it but cant hear anything)

hello im intrested in finding out where i can pick up ther softwear and hardwear to mesure sound on my laptop

Aight, Ive got 2 18" daily Fi BLs dual 1 ohm, with cooling and flatwind option. Then I got a sundown saz-3000d, iraggi alternator, and more 1/0 welding wire than you could shake a stick at. Now I have very limited box building experince, and I know someone that knows someone, that has some experince. But I think he is limited in proper port designing, maybe. He has a shop called 352 Kustomz, small shop, two guys, do some crazy custom stuff. Very skilled in body work. So they start grinding away on my project, Its going to be more of a show box than a performce one. But he keeps on asking me the "port size" recommendation from Fi. I told him 5-10 cubic feet @ 30-37Hz , …

I am doing box plans for free (technically). All that I request you do is sign up for my free ipod link and do an offer. I do everything by hand and I will design a rough outline, cut sheet, and assembly instructions for you. Think of it as trading my time for your time. You can do that offer for free by going through the ancestry.com site.

this is my plan. im building a box that has 4 nightshade 15s. i designed the box on a 3d program to scale. the box is 19.5 cubes. the port is 7inches wide and 38.5 inches tall. that gives me 269.5^2 inches of port area and i need 12-16^2 inches of port area for each cube of airspace. so ill make the port area requirement. the box is tuned to 30hz. i will also be having all the walls 1.5inches thick. everything will be liguid nailed and screwed together.what you guys think? i cant seem to get the pictures to upload. i dont know how to get it from google sketchup to a image hosting site. any help with this?

You can see what Josh (funny guy ) drew up, and then you can see how I tried to tie it all together so all I need to do is lay out the components just like a picture. I used circles and boxes to save time I think the only thing I am unsure of are the woofer -'s and the mid +'s (keep the reversed polarity + (2x) driver in the tower) ... I don't know where I'm supposed to tie them into the neg path - don't know if I have it close to being correct or not, as I just threw them in there. I could always move them right to the main neg lead coming from the binding post if it makes a difference.

On the Termlab im hitting a 144.3 sealed up at the dash with a sweep. its in a trunked cavalier. i just want to know if i can get that score a little bit higher? would holding the trunk lid, sunroof, or doors down during a run help? would more room for air to get into the cabin help? does subwoofer box placement help, meaning how far away from the trunk lid it is, also how about rear seat folded down half way help? how about front seat positions? kind of just trying to get as much of an edge as i can. with the 144.3 run it was all set up for daily driving, not much tuning done at all, as in i didnt play with box position, or seat position or anything like that. i just k…

can someone design me a box for two sundown audio zv.2 15's that will be going in a 04 impala here are the measurements W-35 H-17 D-30 i used the subwoofer calculator on the 12volt and i came up with 8 cubes
