SPL & SQ / Fabrication

well..just got back... took second in the local class with a 144.4 outlaw on the new tl using my orion. lost to a box i built,lol, in a grandprix..two eclipse ti 12's (one blown), two memphis 1500d's, two optima's and iraggi alt..145.6. the local class was a run what u brung sorta thing...so my stock electrical system (save the big three and redtop optima) was my downfall mostly i believe as my voltage drops are huge! but at least i lost to my own enclosure..lol! and helped a friend to a 147.6 with 4 memphis pr 12's and an american bass amp...and a first in his class, 0-300 stock. time for a new system... wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Is the opening of a slot port supposed to be on the face of the enclosure, same direction as the sub is facing? All the boxes I have seen have them there...is that the requirement, or, just common way to build it?

Well i got my RE comps from the SIN group buy a while back and it has just been these past 4 weekends that i have been working on making some tweeter pods....well actually like 2hrs of work total each day. i am finally up to paint...well here is a look back. Well here is the 2 molds. im not going to go into how to do this because there is already a thread filled with Fiberglass Tutorial Links Stickied. ya i know, the mat wasnt 100% saturated...old resin doesnt like to soak. Streching the fleece glassing the fleece a hole cut i know, not a good mounting andle by any means but we alerady discussed this for like 3 pages in a thread and the RE's have swivle mounts so …

Info: 2-10" Alpine Type-R's in a sealed enclosure made from 3/4" MDF Volume: .882 ft^3/sub Inside dimensions: 10"x10"x15.25"/sub Outside dimensions: 11"x11"x32" Cut pieces: 2-32"x10" top & bottom 2-32"x11" front (subs will be mounted here) & back 3-10"x10" 2-sides and center divider How does this look? I assumed that 3/4" MDF is like 3/4" plywood in that the actual thickness is 1/2", or am I wrong? Thanks, Ed

Any use this program to model stuff? If so, im too broke to pay for it

NEED SOME HELP DESIGNING SYSTEM FOR 99 DODGE QUAD CAB, HAVE A FRIEND WITH CHEVY EXTENDED CAB WITH 2 ROCKFORD 10'S UNDER THE BACK SEAT AND SOME OTHER SPEAKERS IN THE FRONT DOOR PANELS. HE HAS 2 ROCKFORD 1200 AMPS, THIS THING ROCKS BETTER THAN ANY I HAVE EVER HEARD. I WANT MINE TO BE AS GOOD. DONT LIKE RAP OR BOOM BOOM MUSIC, WONT TO ROCK WITH LOTS OF BASS AND MID RANGE, METAL MUSIC COUNTRY AND CLASSIC ROCK. WANT TO USE ALL ROCKFORD FOSGATE STUFF, ANY SUGGESTIONS??? PLEASE HELP, THIS STUFF IS DIFFERENT THAN A SUPERTUNER 3 WITH 200 WATT EQ.

Here is an idea i am throwing around for my 99 neon... 5.25 component set up front for the hi/hi-mids have 6x9 holes in the rear deck, but will enlarge them slightly to encompass 8"(7.25 cutout) midbass drivers 50-200 hz response.. then have 2 12's in aported box in the trunk Is this a sound design to put the midbass on the rear deck?? I have read numerous things about running mono for the rears/keep away from highs back there cuz it moves the center image backwards types of things... Also is this going to be terrible placement for the "free air" midbass speakers on the rear deck having their back wave interfering with the sub output... (really the rear deck is the only p…

I have read alot on building ported boxes in the past couple of days but here is what i was planning on.... Putting two kicker 12" L7's in a ported box. Here is my ? When porting the box is it more efficent to put one port out the middle where both chambers connect to, or to port each individual enclosure on either side/ or in the middle just separated!? If using just one port is there a need to separated the two chambers before the port?? THanks!@

I know that ports are most efficent when they are facing on the same plane as the driver, and that you loose any gains form the port if it fires 180 degrees from the driver. but, how much SPL will be lost by aiming the por just under 90 degrees from the driver? In a (hopefully) up comming enclosure construction for an XXX18 in a Mazda B3000 ext cab putting the port on the same plane as the driver will be very hard, so i am thinking of having hte port firing up and the woofer on a slanf facing forward.... how will this compare tothe woofer and the port being on the same plane? im not concerned with not being loud, i am concerned with not beating a friends 4 JL w1v2's with…

Just starting an install journal here. Ive made most of the progress so far only having the trunk left to do after finishing up the install of the kicks/horns. Feel free to ask any questions. See sig. for other components in install. thats all fer now folks

I've got ~13 cubes net - up to the window line in the cargo area of my truck, while still fitting (3) batts. I've got power on tap upto 6kw nominal. All ported, nothing tuned higher then 38hz for music and daily wangage - preferably more like 28-30hz. Take Your Pick... will build on Wednesday. Thanks gent's -Nick

This is for 2-10" Alpine Type-R subs (SWR-1022D), and will be powered by an Alpine MRD-M501 amplifier rated at 550W into 2 ohm mono. These are my inside dimensions: Height 10" Depth 10" Width 15.25" Total is .88 ft^3/sub Total outside box dimensions are: 11"x11"x32" I need to put this box underneath a rear strut bar and from the bottom of the bar to the trunk floor is 11 1/2". Will this work or should I scrap the strut bar and build a taller box? Any help or suggestions are appreciated. Ed

Here is a link from CDT that has basic knowedge on staging, also includes many install guides and specs for their products. http://www.cdtaudio.com/downloads.htm

Steve got me interested in the idea of building a console that I could put a decent SQ sub in. My thoughts were to have something like this, Box will be fabric matched and coushioned <SP bolt to surrent center seat/console location, have brackets that fit stock storage box on it. Each end of the box will extend behind each seat for added volume, passenger side extention will be the port. OR Plastic or vinal covered glassing to look similar to the current console on the LS & LT extended cab with basically the same layout. OR But an existing color matched console and modify it to incorporate the box design. Ideas and suggestions definatly welcome. I will make a b…

I'd like a box cabinet plan drawn up I don't know if I'm going with this design yet or not, but if I do I'd like to have a plan for it. I'm basically doing a homebrew version of this: http://www.omegaloudspeakers.com/ts33.htm Using these drivers: http://www.madisound.com/pdf/fostexcabs/fe126e_encl.pdf If it models well, I wouldn't mind going with a tower speaker instead of a bookshelf - although I don't know exactly how it would react. Thanks...

i'm almost done. i didn't use any glue, cause if it won't fit threw the hatch, then i'm gonna have to put it togother in the car:( it is ~5.9ft^3@25Hz for my 2 RL-p 15's. it has to stay in the hatch(backseat has to stay functional), and with the side windows in the way, this is as close as a wall as i could get. enjoy! more tommorow

i just traded my one 12" MTX 8000 series for 2 10" MTX 6000 series (4 ohm). sounds like i got screwed but the 10 sounds so much better. now i want to get an enclosure for both because the guy i traded with only had an enclosure for one. the enclosure it is in now is about 1.1 cu. ft. it sounds pretty good, gets decently low and decently loud, but doesnt really exceed in either category. i listen to all kinds of rock and some rap occasionally. so i want an LSQ setup. i cant decide whether i want to go ported yet or not. i'd love to but not sure i have the money because i dont have the knowledge to build my own. i am just wondering what the perfect size sealed and port…

How do you guys carpet your boxes? I am going to be carpeting on saturday and was wondering what you guys think is the best/easiest way to do it.

BEFORE AFTER! do you like it?

So i was a little bored today and had an hour to kill. I figure, all the equipent I have laying around... I might as well put something in the truck and play around. Dropped in my old CRX-stlye box, pair of RE SX 15"s, and an Orion 2500D. Setup for 2kw before Imp. Rise. Ran a sweep, found the boxes peak with these woofers. Burped a couple of times. Then went back to a sweep to get a good reading before the batt drained too much. Stock Delco batt (3 years old). So far for this season in Street C, this would've put me 6th place. http://www.termpro.com/asp/leaderboard3.asp Not bad for dropping in and not testing anything. -Nick

i have two idq12's in a 1.7 cubic sealed box powered by one dls A6(875@2ohm-1200@1ohm). i listen to mostly metal so i need the sub to be able to keep up with the fast double kick-drum. the problem with my set-up is i can keep up with the beat but lack lowend. i took out my xtant 1000/1 think it was the subsonic filter frequency blocking low notes. it must be the box- what is the best application for a truck

Im getting some nice port noise with those 3" 90* PVC elbows in the SE enclosure. I was wandering if it would be worth it to swap out the face and put in a slot port instead of thse 2 3" Aeros ? If so, would anybody be willing to help me with the port. Only things i suck at are ports and alarms external is 29(w)x17(h)x9(d) Id like to do an L style, but if thats not possible labrynth is just fine. SE depth is 6 3/4" Tuning: low 30's ( if possible)

I'm just wondering, being new to this forum. Who on here competes & who doesn't. Also, what sanctioning bodies are you all in? Also, any1 on here also on the CS&P forums?
