SPL & SQ / Fabrication

Wassup y'all, I'm about to start a box for a 21 in death penalty. I'm going for 9 cubes at 30hz with 3 8in aero ports which equals 150in of port area. Is that too much? I've heard the sub will not handle much power? Someone help me out haha

Can anybody tell me how much of the port length I need to get rid of in order for this box to be tuned to 32hz? Sound Solutions Audio - 15" XCON Optimal Ported Enclosure Please and thanks!

I have been reading on t-line boxes for a good 2-3 hours now and am just not understanding the design part 100%. Only one that I have read and felt like I somewhat understood was the "u-shape" style design. I have always done slot ported boxes and was always happy. I think it is time for me to learn a little more about boxes. So far, this is what I have grasped Say I wanted a box tuned to 34hz. I would take 1130 (the speed of sound,) divide that by 34. Which would lead me to 32.25ft (rounded a tad). I would multiply that by .25 because I am looking for the 1/4 wave length. I would need a port 8.0625ft long. And SD equals port area? Also I am aware this is not a full t-l…

Right now my enclosure is 6.5 cubes tuned about 33. Port area is only about 82 . . Was wondering what kind of changes you think I could see by lowering the volume more to increase the port area to cubic foot ratio

so me and my buddy decided to make the box for my 15 thats on the way and here are some pics gonna carpet it soon! tell me what you think, and be honest!

Hello all, I am building a budget spl system an need help with the enclosuer.I have one Sundown audio saz-1500d an two audiobahn aw1206t 12" subwoofers. The enclosure has to be under 7 cu ft outside. My car is a acura cl 1997 I have two Orbital 950ca batteries ,1/0 wire a fusion preamp with 8 vols outs. I know the flame q is not the best sub for spl but I can get them for $130.00 per set.

i'm new to car audio, but would really like to learn to custom build and fabricate (amongst other things), so i was wondering where i could go to learn to do those things. i know there are tutorials, but i learn better with hands-on experience, so are there any places anyone could suggest. thanks for your suggestions

Okay, Elderado told me that in my car, i have a gas tank between the trunk and the back seat. I actually think that the tank wall is my trunk wall. Anyways, Odds are good that I cant get wire back through any cracks there.. So, where do I put it? <pics tomorrow when its daylight> So, I was thinking maybe right behind the drivers seat in a nice sealed box with some plexy glass over the top so it doesnt get stepped on. Either that *not behind the passenger seat becaues its always moved* or I can stick it in the rear deck. Like, I could be able to drop it inbetween the two rear speakers? But I would need to check the space between the deck and the gas tank. Als find ou…

I am going to my 2nd comp. this weekend---state finals of WV---I will be competing in the Stock SQ class and I am nervous hoping I do well---I think I have tuned my car so much it is starting to sound unnatural---I need to leave well enough alone but if anyone here knows me knows I can't leave anything as is.----sorry I had to rant alittle.

Has anyone ever built, seen, or heard a deathbox enclosure? I would like to build one myself but have only heard about deathbox and I never found the build plans. I would like to test the enclosure with a 10" mtx woofer and see what the enclosure is capable of. I stuffed the mtx in a sealed enclosure and it produces tight bass but nothing fantastic about it at 300watts. So if anyone knows where I can find the build info for the deathbox, I'd really appreciate it! Or let me know if you have ever heard one in person!

Crazy, stupid, or cool? Thinking about doing wall with 2 18's. Not for spl, just daily pounding.

Hi everyone I am about to try my hand at making a box of a different type for the first time. Mainly I'm doing this because it is very interesting to me and also because I can stick this speaker in my girl's car and if it sounds awesome I;m hoping she allows it to take up that valuable "grocery getting" real estate in her trunk. So I'll start here. Vehicle : 2002 Lexus GS300 Location in the vehicle: Trunk Space available (Length x Width x Height): 36" x 24" x 22" Subwoofer make and model: Ampere Audio 2.0 8" (spec's below) Subwoofer Size: 8" 300 Watts RMS Number of Subwoofers: 1 Type of Port (Kerfed, Slot, Aero, etc.): slot (T-L…

Hey all.Is it true that you can build a wall and then slide it in your car?Ive heard of people doing this but wasn't sure if it was real or what.If its real how would I go about doing it?I want to build a wall but I dont want to spend 1200 bux to have some one build it so I was going to attempt to do it myself.I have a 2007 Dodge caliber and was wanting 4 15's if it helps any.

Hey guys, got a huge favor to ask, i'm doing my first build for a customer, for a neighbor, for an Icon 15d2 in about 4cubes @ 28hz forward firing in a 01 deville What should I shoot for for port area, and have any of you done forward firing setups in a deville before? I'm tryna make a good impression lol. We're going to carpet it to match the trunk for a stealthy look, well, as stealthy as a ported fifteen can be lol. It'll fire through the ski pass. I guess I'm super anxious about it since building for yourself you never have to worry about an upset customer, you just rebuild. Thanks in advance. Edit: It's for a blend of all types of music, and the mids and highs are t…

I recently opened up a tint shop and have had a lot of customers wanting audio, so I just picked up the Sundown line. I've been an installer for 14 yrs now, but all the shops I've worked at did cookie cutter systems with pre-fab boxes so I never really learned how to make a box and match it to the subs. I've built plenty of boxes, so the actual building is not what I'm looking for it's just getting the correct size and port length I need. I see a lot of threads recommending box calculators like torres ect. which I've downloaded, but I don't see how you're converting the sub specs to box design. I found the AJ vented designer program which does this (I'm looking to built m…

Current setup is Mach 5 MLI and Seas H1396 amplified by an Eclipse EA4000 and all the processing is done by my Alpine 9813. I'm very satisfied with the midbass output and the top end, it's just that midrange isn't cutting it After seeing Ryan2's idea with the Fostex FF85k's I thought trying a pair and ditching the tweeters. I don't want to invest in the H701 at this time and try 3-way (would require some sort of controller too and another 2 channel amp, not to mention the extra room ) The problem is placement. I have no room in the dash to mount them. Pics of the "locations" : One idea is to use the kicks. Passenger side is ok, driver's side could work but there's v…

i sold my crx i coudnt keep fixing it anymore my transmission went out i have bought the 18 xcon when they were on sale used for $300 and i now financed a 2003 acura cl!!! i miss my rex and now i cant use my 18 xcon i need help deciding new system i dont wanna tear my new car up but i want it to be loud and have some sq without tearin it up

Hey guys! I did a bit of reasearch but couldn't find a good topic about this. What do you guys reccomend for some good box building tips for the best box possible? Not like designs so much (Although if you wanted to post set-ups such as like...Explorer, sub up port back (as an example) that might be helpful to some), but things to do in the box. Things like: Rounding the port edges to flairs 45 degree angles in the corners for standing waves placing the subwoofer so its at the back of the port length where to add braces so that turbulence is minimized (or using rod threads or your favorites) those were a few I could think of as example and I'm not even sure if they're al…

Do you guys think I can get 4 dcon 10s in a 36"w x 16"h x20"d ported

I have a gmc Sierra ext cab and I have a half wall box. How could I secure it so if I crash it doesn't kill me?!

I have never done a wall before, and i am really interested in them. If its not too much trouble i was wondering if i could get schooled on them -- how to prep a truck for a wall, the do's and dont's, bracing, etc. etc. etc. I would like to become confident before going balls deep into this build and I don't want to be slapped in the face by how little i know half way into the build, ALSO i want to know what i am getting myself into before i start cutting. (ported, 10-20 cubes) i seen the build a wall build and it had a SHIT load of 2x4s.. would i have to do this to my truck? The truck will be a 1986 GMC Sonoma (S15) ext cab and the equipment is 2 or 3 (depending on how …

Here is the quick rundown: 4 Soundqubed HDS300 FS 33.65 hz QMS 6.912 QES .769 QTS .692 VAS .782 Ft3 Outside dimmensions of box: 16.3"x41"x27" = 10.44 all setup in a common chamber Port size: 8"x40"x65.88" @ 30 hz I believe this is all correct but what a double check before I build this box. Thanks

Hi i've had my fi btl in now for over two months and although im fine with it i've noticed its not hitting the highs quite as well as i want it too....but the lows are exremely awesome i have the box tuned to 33hz could that be the problem...any help is appreciated.

Ok so i have been doing a lot of research for the past 3 months on my plans for a setup. i decided that i am going to go with 4 18"Fi SSD in a blowthrough enclosure designed by peter kulicki (still designing) with a Sundown 3000D (still saving up for it). but my dad told me my subs are going to kill my highs. currently have 4 kicker 6x9s doing the work but i am looking for some suggestions on an extreme setup for some highs in my single cab. by extreme i mean i want way more than a set of comps and tweeters. any help will be appreciated if you wanna check out some pics of my truck you can check it out here!! http://www.cardomain.com/ride/797852

ok ok so i had a lil show today.... and i heard some stupid ass shit come out of peoples mouth... . and some shit that made me prove my point of running 15's IE "yeah fam thats why i like 12's you can hear them hoes from far away!. "yeah you cant make 10's loud " "i like 15's cause them hoes hit low you cant get that sound from a 10" " so you can make 12's loud like your 15's?? nah nah nah i dont belive that " but the good out of what i run.. "damn thats only 2 15s!!?? " " i thought it was 2 18s" i got two 15's but they dont hit like that " so anyway im thinking in the black town car i can do anything... and i was thinking 2 or 3 18's ... then i was think…
