SPL & SQ / Fabrication

since I own a scion, I frequesnt the scion bbs. Well, this guy (works for or at eDesigns) is putting 32 7.5" eDesigns woofers in the back of his TC. I guess the project just started today...but here are some pics he posted.... This reminda me of the Bose 901 series home speakers... any thoughts on this set up? I imagine it would get pretty loud. aside from being overly rediculous..what are the advantages of using 32 7.5" woofers, as opposed to 2-12's..? ...hhhmmmm....maybe I could do, like 16 rl-i 8's in my scion....hmm....

Hey guys, I was messing around with some box plans, and for the recommended box for two rl-i 8's (.6 CF @35 hz) the port has to be over 106 inches long. That is almost a 3 CF port! Anyone know how I can get the length down some? Check my math, but I'm pretty sure this is right.

Want to learn how to fiberglass? check this tutorial out, he knows what he is doing. http://www.automotiveforums.com/vbulletin/...ad.php?t=416484

it didnt hit me how big it was until i started cutting the pieces, seriusly, its like a mini dog house... I gotta go buy another sheet of mdf, dam thats 44bux...22$ each I have my friends lil d-snap camera, but he didnt giv me the usb connector to get the pics off of the camera hopefully i'll get it 2ma.. and hopefully i'll be finished wt the box by then also. now i still gotta order the subs

Who has any experience with CF? such as: http://www.fibreglast.com/category.php?cat...src=HelpfulProd

basiclly the lower i tune my box, it seems the higher DB i get on the graph. @32 =138 @26 = 139.4 @20 = 141 That can't be correct can it?

well i was expecting a db drag. and i get there and there is like 4 judges that sat in the car to judge on overall sound. they said that my rl-p's were by far the best subs they've ever heard!!! needless to say i took first place and a $500 gift certificate to extreme motorsports. i was really wanting cash, cause i don't wanna spend any money on my car so i'll probably just end up selling it.... but either way i took first

Is it possible to wire in multiple computer case ball bearing fans in my car? Is it a matter of taking the black wire and grounding it, but the red power wire, can i just wire it to my distribution block? How will i deal with the voltage? Thinking about mounting amps in a long thin enclosure with plexiglass top and have the fans suck in air on the right side and have the fans suck out air on the right side for ventilation. Maybe ill throw in some neon lights to make it look good. Is this just a pipe dream or can it be done? Any help would be appreciated. TIA

18in Sx btw . Ok, I got 17.31cuft to mess wt here 43.5x27.5x25. The box is gonna be ported to idk 32 sounds like a good number. Suggestions? It will probably be dual chambered, wt the port on the end. Is that to big or not big enough is my question. It says it only needs 6cuft for sql, so i guess 8cuft for one sub isn't that bad.

For those with hatchbacks and/or hatchback experience. Folding rear seats, so large enclosures will work. What enclosure has worked best for you? CRX style? Sub up, back, forward, or angled towards glass? Port up, back, forwatd, or angled towards glass? Daily driver. I'm tempted to try something in the Mazda for the uberwoofer. Can be pretty large, so uncommon enclosures can work as well. It'll boil down to having the sub and port firing forward between the seats or any of the above ways.

what would you guys prefer to use to smooth out the corners inside a box, putty or bondo, (and which brand) I might grab some resin and hardener for my RL-p box, I want it perfect before the RL-p goes in, I shold probably do some more internal bracing to make it as stiff as possible to preserve as mush SQ as possible

If someone was going to build a sealed enclosure, and the woofer in question listed a box size of, say 0.75^3 to 1.5^3, how do you determine what size ^3 would best suit the woofer? Is that something that the tsparameter would tell you? Or, just build something in that size range and get equal results??? Just curious...

I am just wondering a little about amplifers and competition...... this makes me think because the wattage output of amplifers on the normal consumer market, is growing exponentially fast, for example a few years ago the Earthquake D2 was one of only a few amplifers that could be had for a not so bad price and was doing well over 2000 watts.... I am curious more about this in the purpose of street classes where 12volts and only one battery is allowed now Orion, Kicker, Hifonics, MMATS, PowerBass, American Bass, SPL Dynamics, Harrison Labs, Tru Technologies, Phoenix Gold, Zapco, Cadence, Rockford Fosgate, US Amps (the list goes way on) all make or sell a amplifer model tha…

i am trying my hand at some horn's for the mids from my re6.5 comp set, the tweeters blew so i got new comps coming, and desided to put these in the living room. so how does this look? anything you see wrong or horn tips would be greatly appreciated

Sorry for the long post. I just bought a pair of Beals Bros 8" midbass drivers. I have no specs on them. I know you are probably saying to yourself, why would he buy them if he doesnt know anything about them. Well they were cheap and in great shape. Now on the the questions. As many of you know I am currently running a set of CDT HD-62 pushed by a Memphis 16-mc300 ~150x2@4ohm (depending on voltage) ~240x2@2ohm ( " " " ) Here is where the questions start. The Beals is 2 ohm nominal and the HDs are 4ohm. that would make the final load 6ohm for series ( not enough) or 1.3ohm for parallel ( too low). I have heard that lower impedance=more distorti…

I was playing around i bbp6 and this is what i came up with, is this right or wrong? Optimum Square Prism Box Parts 1 Top, 1 Bottom: 13.27

Any competitors with a trunk here? So far I am at 147.4 legal on the term with no testing and a box with the wrong tuning. Anyone have an tips/hints?

is there anyone in the Dallas area that could help me build a box?

Ok, here is are 3 chioces of a mock-up for the install. I was able to raise my air tanks up high, and now I can fit a box underneath. Here are the 3 possible ways to mount the amps. None of these ways will they actually be attached to the box. I will weld some aluminum and stand them off a 0.25" or so. Mounting the amps on top, I like the most, but one amp is slightly shorter than the other... Mounting the amps on either side, and the RL-p in the middle..though, I dont like the M's facing opposite of each other.. Mounting the amps on one side, and the RL-p on the other... Taking a vote..without a poll I guess.. Got in all my wiring today, so just waiting on the soun…

Ok... In the process of building a new sub enclosure, fibreglass of course. And I am porting it (RL-p 12). Now, I do not want to use a slot port, what options do I have for nice flared ports? What dia should I go with, is 4" large enough? I saw a couple options on partsexpress, wondering if it is possible to use normal plumbing PVC instead of the supplied stuff so that I can get lengths longer than say 17"? I'll try to get pics up on the build, but, me being digicam poor, may not be able to get any up until it is completed (or I go through a complete film on the old-fashioned cam-era).

Ok my buddy has 2 Audiobahn Flame Series AW1251T 12

I was wondering, I am trying to figure out how to not make a box but find out measurments ... well what should i look for when I am lookin at the sub specs and what just what do i look for to make sure everything is perfect

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?

Hey guys. Its time to try something new. Not sure what will happen to the sound if i tune my box higher or make it larger. I'm 1.5^3 tuned to 28hz now. love the flat response curve and helps the sub sound really low. What would happen to sq if I make the enclosure larger like 2.0^3 and/or tune higher? TIA
