SPL & SQ / Fabrication

i talked to my cousin earlier and he was explaining different box designs to me, he said that he had a box that was a cross between a t-line and a horn design box, he sent me an attatchment w/ pictures of the different types but i cant find formulas anywhere, i used the search but none of the links for formulas worked so i was hopign someone could help me out... thanks

so ive been looking around for ideas how to get mach5 mli 6.5s and tweets in my doors, but the mounting depth is kicking my a$$. the magnet will hit the window when its rolled down if i put it in the stock location. im wanting to do minimal modification to my doors to keep it as stock as possible*. i saw this and figured it would be perfect for me, if it wont hurt the speaker at all. i cant think of any reason it would, but im just making sure. should i seal behind it with something, or just use some deadening on the door itself? any input would be nice, thanks! hope this works, and if it does work i hope it comes out cleaner than that one

I know I've seen plenty of people use spray/roll on bed linings for the outside of their enclosures and such. I am wondering two things though, was it applied to the bare MDF or with a primer on the MDF first and how well is it holding up after "x" amount of time? I'm about to start on the enclosure and amp rack for my Jimmy. I had planned to paint the port to match the truck and use standard charcoal colored cabinet carpet to cover the box and amp rack with. Though upon thinking about possible liquid damage to the MDF on the floor/amp rack I'll be building I thought perhaps the liquid bed liner may be the better route. I have no experience with it though so I was ho…

Okay so I went to Home Depot to get some MDF, Glue, & Screws. So I see the 3/4" MDF and grab a sheet. Then I get home, take it off the truck and find out it's 5/8" instead. Would it be okay to use 5/8" instead of 3/4"? Its going to be for a Single Cab, Downfiring Enclosure, With a Double Baffle. Sub will be AQ HDC3 12"

I'm gonna build a new box for two 12's and was thinkin about porting it through the rear deck with two 4" ports with the subs at an angle to the back.What do yall think about that?

I've got two of these but temporarily I want to see what one can do, I'll be running it off of 900wrms. Anyone want to design me a nice efficient box, tuned anywhere from 27-32 hz? Sub will have to be facing forward, aero ports preferred, 6" PVC pipe is what I'd like to use. Max dimensions (to keep it under window line) would be 54" length x 22" height x 15" depth.

I am currently waiting on my 1st xcon and want to run 2 eventually but don't know if I can. I can slide a 31W x 12 3/4H x 29D through the rear seat opening. That is about the max size i can do through the seat opening i could go an extra half inch in the sides and maybe an inch on height but would be tight squeeze. Also i want ported if possible. Thanks for any help.

I was cleaning out my room, and found some literature that came with my DLS components. I didn't notice this bit of info when I was doing the install. But DLS recommends a chamfered baffle for the midbass. I simply made 1/2" birch rings with no chamfer. My question is, will I notice a big difference in midbass response by going the chamfered route? The rings are fairly thin being only 1/2", I don't think the backwaves are really hitting it. But I want to get some second opinions before I take my doors apart to redo the rings. http://www.dls.se/files/701/2/baffle_installation.pdf Pics of my baffles: passenger side driver side

I have a friend that wants a box built for a 8" sub. I have some 1/2" MDF that I could make it out of. The box will be sealed and not have a lot of flat surface (maybe even some glassing involved to make it fit). Would this be a good idea? I'm not sure about the thickness of the MDF. The sub will only be seeing about 200rms or so.

Hey guys, I have been modeling different alignments for my Dayton RSS265-4 HO woofers. I like the look of 1.2-1.4 cu.ft after displacement for both of the tens, tuned around 30 hz. My question to you guys is how much port area I should shoot for? Would two 3" aeros be adequate? According to the modeling program, I would exceed 25m/s vent velocity using 2 3" aeros, but not by much. This install isn't meant to shatter spl records and each woofer will probably never see more than 300 watts, so taking this into account I don't really think I need such large port area. Looking for suggestions, Thanks

Does anyone know any online dealers that build fiberglass boxes anymore for a decent price? I emailed Fisher Audio but they no longer make FG ones. I would do it locally but they charge an arm and a leg for them.

Hello, im building a box for a loaded 12 btl. i have an odd shaped box i made to fit under my silverado back seat. my question is how should i run my port/s. the box is wedge shaped with 3.6 cubes gross. the box dimentions are 11.25 high in front 8.5h in back 53.5 long and 16 deep. any idea on port location? trying to get 14 sq/in of port per cube seems hard. thanks steve height1 11.25" height 2 8.5" length 53.5" depth 16" the sub will be facing up on the drivers side

After doing the math i come up with a .825 cubic foot enclosure which doesn't seem to leave me with room for ports. Can someone help me out here please? What should my internal volume be? I used the box calculator at the12volt.com, is there a different calculator I should be using? Thank You to anyone who can help me.

This goes out to Team Defj/Team Xtreme's Jeremy Smithers. He just posted a 157.8 at the IdbL Event in Fort Drum which gets him 2nd loudest in the WORLD in that class!!! Awesome job dude!!! You definitely deserve it!! It's been a long road that's gonna pay off in the end!! for the good guuys!!!

Hello all! I am looking to reconfigure my trunk set-up in my Mazda 3 and am looking for some feedback on my idea to see if this would give me my desired result. Currently, I have the subwoofer firing straight to the back of the car, with the port opened up to the rear deck ( I use a flared round port). The problem is that the rear deck is completely solid and this causes quite a bit of rattling, even after deadening the whole trunk. What I am considering doing is rebuilding the box to have the sub firing straight to the back of the car, with the port opened up on the back of the box. In order to do this, I would need to put an elbow on the PVC port because the box will…

I know I never start these topics, but I am wanting to build a really cheap fun Street B install for my truck once it is out of the shop, the most cone surface for Street B competition is 3 10's ok so I have narrowed it down to Options: 1 - the RFD 2210 (HX2 single 4 ohm 10") $109 2 - the Kicker S10D (round solo baric singl 2 ohm 10") $109 3 - the Cerwin Vega Vega 10" single 4 ohm $109 4 - dont sell my 2 eclipse aluminums and buy one more svc 4 ohm aluminum and compete with them (cheapest would be the 4th option, but I am hesitant to por them, warbleed really helped me out with figureing out a ported box design despite eclipse's lack of info for porting the Aluminums…

Sorry for another question (just taking advantage of my day off). I just finished up damping my door panels, the sheet metal, framing, and plastic panels,as well as the rear hatch with eDead 120 and Damplifier Pro. Probably have used about >80 ft^3 so far. I am doing my entire roof and going to do the floor soon too but I am having trouble deciding what to do next. I keep reading very different theories about what to do, whether to use closed cell foams or open cell foams and where to use them. Some of you have recommended websites to buy different products but just need to know how much and what to buy. I have a lot of room in my doors between the interior plast…

Does port/woofer aiming really matter that much in an SUV? I'm looking at placing the box in the passenger rear corner with the woofer firing cross cabin and port forward.

ok, i'm gonna risk one hell of a flamming here and ask you guys. i was nomeened R-tard of the month on CA.com for saying this so chances are it's gonna happen here too, but what the hell K my question is can you guys hear the difference between a 4 ohm and 1 ohm load? now im not talking about sitting in someone else's car and knowing it, but if you have a 2x2 sub and wiring it to 1 and 4 ohm load. i have tried it with a two different amps(a 2 channel in 2 ohm bridge) and my current RF bd 1000.1. although on a 1 ohm load and lower it ponds like a bastard it just sounds too off, sort of muddy... this all applies if the amp is stable on those loads of course just curious...

Hi guys, I will be building the pre cut enclosures I calculated under RE enclosure calculator but there are a few things I would like to verify. I would like to tune the box between 33-35Hz @ 1.8-2.0 cubic ft. However, I just read that the RE calculator is not accurate. So I searched and found this website Enclosure Volume Calculator (EVC) and made the following calculations: Box Width 23 Inches Box Height 15 Inches Box Depth 15 Inches Material Thickness 0.75 Inches Number of Drivers 1 Total Total Port Volume 258.188 Inches3 -----> see calculations below: Port Width 13.5 Inches Port Height 1.5 Inches Port Depth 12.5 Inches Driver Volume …

Hi folks. I just picked up a pair of L7 10's to go in my single cab 06 Sierra. I would like to go ported if I can make it play loud and hard enough over a sealed setup to be worth while, however I am not sure as to what my best bet would be in terms of porting for this. The enclosure dimentions will be18"Hx57"Wx7D which is good for 2.91 cubes if my math is right. I've been running 1 12" powerbass L12 in a 2 cubic ft ported enclosure with the sub behind the pasenger seat and one 4" port firing up from the top on the oposite end and it has sounded pretty decent, but I want to run more power and get louder and due to mounting depth issues a more substantial higher power ha…

Went out to a Texas Bass Productions event today with the Sebring wit 1 12" Soundstream SPLX Quad 1 ohm.. All 3 runs it did a 151.3 Got 1st place in my class(no one was close to me). Brian(Lord Baccus) did a 151.2 with a set of bad RCA's with a Pierce Audio Products 1 off(specially made for him) 15" MOAB subwoofer, ...sorry bout that Brian..we'll et em' next time! Every ones asking about the Sundown Audio amps that me and Brian are kicking butt with....most people haven't heard of them...they are getting a ton of attention... Hoping to get higher on this single 12"...

how does it measure the frequncy of the port if it does not know the displacement of the sub?

My car audio team is holding a Car Audio competition in the town of Lodi. Here is the link http://www.team-bio.com/2nd_Annual_USACi_Sound_Off.htm This would be a nice little meet, for some people who want to come out and have a good ole' time. There will be a ton of cars, a ton of extremely nice cars, and its just alot of fun. Last year we held this event, we have around 50 cars.
