SPL & SQ / Fabrication

Hey all... got another question here . If you use aero ports, is it possible to build the box smaller in relation to a box with slot ports, or is the port displacement the same for both types? Thanks

Getting ready to do a little sound deadening this weekend. This is going into an 07 Altima. Do I need to remove any factory deadener that is glued to the floorboard or any other place. I'm not talking about any jute carpet or material that can be easily removed with my hands. I know that some cars have factory carpet/rubber like padding on the floorboards, does this need to get removed or can I just deaden around it? Thanks. Thanks!!! :drink40:

does someone have any box designs for a 6.5inch sub (on computer,links,...) ... any type of enclosure designs r welcome the sub used will be a http://www.tb-speaker.com/detail/1230_04/w6-1139si.htm

I wasn't sure where to post this so it will probably be moved.. But im planning a new box and im debating what frequency to tune to.. The thing is that i have a box in my truck now that is tuned to 40Hz and I want to play sine wave tracks (30hz, 31hz, 32hz.. and so on) to determine where my box peaks at with cabin gain. I believe this will help me make my decision because I don't really know what hz is playing in a song and say my setup starts dropping of around 45hz now.. I may want it to drop off around 35hz.. Also i will use the tracks to compete if i ever build a loud setup. I buddy of mine used to have a cd with tracks like this so I know they're out there.. Could…

Alright, well, for a build I am going to be doing I can choose between 2 4" aeroports, or 1 6" aeroport. When I put the 6" into WinISD it tells me a length of 23.25" is needed for my tune. And when I enter 2 4" ports it tells me I need a port length of 21.5". Now, is that a combined length between the two ports? Or does each one need to be 21.5" ?? Thanks for your help.

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

hi, i have been doing so searching and i see that some people use clay as a spacer and i am wondering 2 things. how well they work and the other being how do you do it. cuz i need 2" spacers on the cheap side and all i could think of on how to get the clay to work for me is use something like these http://www.homedepot.com/webapp/wcs/stores...03+501959+90025 to give the clearance and then just fill in the space with clay and more then likely us fiberglass resin to make sure it is seal.

Alright, I want to switch to Aeros from my slot port to give my subs some more airpsace (2 15s with 5.5cubes is a little small for me).. anyways could anyone help me out here, I know how to design a slot port but not a aero port. How many would I need to get proper port area and the length for say 31-32hz? Box is 38.25wx16hx24.5d

I want to design a ported enclosure with one DD9512g to put in my single cab chevy 1500. I want it to be loud, but also as musical as possible. I have about 3.3 cuft to work with. The enclosure is going to be a center console enclosure. If I find the frequency which my vehicle peaks at, will this help me choose my tuning frequency of my enclosure?

Alrighty, so I've got a few question. I'm building a ported box in my G35 Coupe and I'm using a round port instead of a slotted port. I'm planning on using these ports. I've been using this calculator to do it. Right now I've got a 2.0 cuft box, I plan on using 2 ports, and I'm tuning it to 29hz. After clicking calculate, it gives me the vent length of 9.13 inches. Does this mean I'll cut both of the cylinders to that length? Or where exactly does that measurement start and end? Also, any tips on doing a flared port box? Slotted was easy, but I wasn't sure if this is any more complicated. Also, what panel of the box should I have the ports for the best results? If it matt…

I am almost done putting together the box, and someone pointed out that the opening looks a smaller than the other opening. I went out and measured it and realized that I made it 20.5 width from side to side of the port, and 22 length. It was supposed to be the other way around tuned at 33hz. Will this mess it up too much? Is there anything I can do to fix it? What would the tuning be at? Will this lower or higher the tuning? will it mess with the sound too much? I knew I fudgeed it up... I'm so pissed Btw, The length is of the top of the port. If you need, the sides go back 25.5, and height of 5.75

I don't want to keep bugging Jacob if other people here can help. I am building a ported enclosure for 2 Sundown SA 12's . A few questions , would it be good to tune them at 36hz? They will be on a Sundown 1500. Also, What i really need to know more then anything is the port dimensions. The max dimensions for my trunk is 22 Depth, 33 length, 16 Height. A sketch up would be really appreciated with the port calculated and what not! I will return the favor in some way *Shizzon are you around?*

If you run the port externally, does it take up space or add to space inside the enclosure. Same idea as inverting your subs, they still take up space inside the enclosure, correct? Thanks

so I just took everything out of my trunk. which also includes the rug and spare tire. I'm not putting the tire back since I can't get it out when everything is in. so my question is should I put the rug back in? I thought I read somewhere rugs are bad for spl. thanks.

so, im currently redesigning yet another enclosure for my home theater mains. was wondering what the effects, pros, cons are on port placement. using a 3 inch round port. a 6.5 and a 1 inch tweeter. so top near tweeter or on bottom below mid or just rear firing? pros cons? im thinking port on bottom with about 2 inches of separation between port and mid.

I need help making a 2 4in port box enclosure tuned to about 33hz. can anyone help?

im wanting to do a build using a mach 5 audio spl 12,sundown audio saz-3000d combo the question is ,will this be a good candidate for a mass loaded enclosure,or t box on the street. im very impressed with what peter w. kulicki has done with two soundsplinter rl-i 8s but i want to understand the enclosure more because id much rather build myself.

I got everything ready to cut untill I forgot... What tall is the mayhem 12". I have it ordered but don't have it yet. On site says mounting depth of 7.75 inches. I don't know what that means.. Help pleaseeee

I've got some ideas for a speaker project...but need someone local to do the fabrication. Anyone either in NC or VA have the time? Let me know...thanks

i have a sony hu,a dual amp for 6x9's,and a punch 401s running 2 15''memphis pr.when i turn it up where the bass is really starting to hit they go off and i turn it down a little they come back on,however if i fade all the way to subs i can hit them as hard as i want to.any ideas?thanks!!

Will using 2 ports work or will my tuning be off? I'm going to be running a Fi BTL 18 in a 6 cube box and want to run 2 ports, one firing left, and one firing right. as long as I have the same area and length would I be OK?

I'm thinking about making a box for some older Rockford RFP1408's that I have, they are 200 watts RMS each, the only wood I have is a 30"x60" sheet of 1" MDF and another smaller sheet of 3/4" MDF. So, I'm gonna use the 1" sheet for most of the box, and the small 3/4" sheet for the front. 1.25 Cubic feet 1" x 11" port tuned to 33hz What do you think?

what are some tips to get good bass response into cabin of a big trunk car that the seats dont fold down? car is a 02 caddy deville.dont want to break the bank in electrical upgrades and equipment. want to run around 1500w or so. and spend 350-400 on subs not including box

Hope this is the right section. Anyone in the Myrtle Beach/Conway area we are having a metering session Dec 8 at Carolina Audio in Conway. Call 843-455-9121 for info/directions. It's not a show or competition per-say because we won't have trophies or classes, and it's not really a show because there's no forms to fill out etc. Just stop by if you want to get metered on a Termlab for a good price. I hope I posted this in the right place because it was originally meant to be a competition, but we didn't get things really together in time and it's just not going to be big enough to have classes or trophies. Should be fun though, and get a nice offical T/L score without the l…

Just looking for some help I guess. Mostly with the stock classes. The organization i was preparing for is looking like its just about dead (dbdrag). So im thinking it may be beneficial to build towards the rules of iasca. Anyone with experience competing in this format, I wouldnt mind a bit of help.
