SPL & SQ / Fabrication

i need to build a box around 2 cubic feet tuned at 33 htz with a maximum height of 17 inches, does this look right? also, sub up/port back or sub/port both back?

Lets just say I'm building a ported box. And the port is 6"x13" (Round port) How far away should the end of the port be from any wall? For example, the port is on the front wall. How far does the end inside the box need to be from the back wall? I think i remember it being 1/2 the diameter, but i could be wrong. If anyone could help shed some light on this one, it would be a great help.

Whats the best way to mount an amp on a sub box and not have an issue of the vibrations messing up the internals of the amp?

Okay so, I got my designs, and lowes completly messed up all the cuts, so I have to take it back and complain and hope that they give me new wood or something..... So in the meantime, I just "sketched" up this box. Here is a pic here is the google sketchup file http://files.filefront.com/fibtl18skp/;13080625;/fileinfo.html for anyone who wants it Let me know what you all think! (I didn't make up the specs for this, a help from another member on this site did, I just drew it)

Right now this is my setup and trying to see what class I would be in in db drag and others.. Subs:Mass destruction napalm 12"s x 2 Sub amp: Sound Stream xxx-6500d 1 ohms Front and Rear Speakers: PG zx-450 Also what DB range should I be looking at with this setup or DB class. I don't have a TL and have not tested it as I just got it all installed today.. I plan to go to my first comp here in the next month or so would just like to know what to expect.. Thanks

Aight, Ive got 2 18" daily Fi BLs dual 1 ohm, with cooling and flatwind option. Then I got a sundown saz-3000d, iraggi alternator, and more 1/0 welding wire than you could shake a stick at. Now I have very limited box building experince, and I know someone that knows someone, that has some experince. But I think he is limited in proper port designing, maybe. He has a shop called 352 Kustomz, small shop, two guys, do some crazy custom stuff. Very skilled in body work. So they start grinding away on my project, Its going to be more of a show box than a performce one. But he keeps on asking me the "port size" recommendation from Fi. I told him 5-10 cubic feet @ 30-37Hz , …

Where should i put the port? This is going to be in a blazer, and if back how much room should I leave between the port and tailgate?

alrite i started a thread on here not to long ago abou tthe elastomeric coating that steve meade used on the inside of the his box and didntt get many replys. i am pretty much done with glassin the inside of my box but i havent started sanding yet. i read about painting the inside with 2 stage paint making it alot louder becasue the waves travel better across a smooth hard surface. but the only problem is i would have to sand the inside to no end. i was plannin on sanding it to an extent and then sprayin it with spray filler primer and going from there. but i have a deadline in a few months and i dont know if this is going to be possible. another factor is that i will bea…

Im designing a new box for my FiQ for my blazer. I was was wondering where the sub and port should go? Sub up firing, port rear firing? Also if one or both rear fire how far from the tail gate should it be? Thanks

is there any disadvantage to having an extremely large port? lets say 20+ inches per cube?

My buddy had talked to me about building a box for his F-150 for 2 12" Xplods. Looking around I think it may be possibly to get 5 Cuft. (or very close) for the 2 12s. behind the seat I was curious what is the best way to face the ports and sub. I think the only way to face the the ports is up, but I do have the option of either down facing them down or foward. What is generally best practices for SPL?

Ive got a sundown 3000 amp and a 300amp circuit breaker. ive been to a few comps and my circuit breaker has blown in some of my runs. Is it ok to run the system without the circuit breaker just for comps?

okay guys, i am lookin to build a new box for my 2 12" kicker cvr's, i am wanting around 34hz for tuning and here are the dimensions i have to work with, 39"w x 17"h x 17.5"d and plans would be great i am either looking for the port and subs facing the same direction or subs foward firing and port side firing, any plans would be nice, and i am looking for a slot port, i am not going to mess with a pipe since i dont have a hole saw, thanks in advance.

i have a 93 nissan sentra and i purchased a bl18 how should i build the box to fit into the trunck withough compromising sound quality

If i use a flared areo port in a 2.5^3ft box would one four inch be alright that would be 12.5 square inches port area. Box will be for 4 8" subs

What would be the best way to wire into the box. Best as in the most secure, and most current flow. A friend of mine just drilled holes and fed the wire through, then just siliconed around to seal it up. I have also heard of people driving bolts through and wiring to them. If this will work, what type/metal bolt would be best. My last setup used actual terminals that I got from Sound Advice. I siliconed the back of them in, but not sure if they were secure enough. All advice is appreciated.

I am starting my wall build soon; I think I have a general idea on how to go about it. I

Hey guys i was just wondering do you have to break in subwoofers?

I decided to temporarily put in one of my SE12's in at 2ohms on my T3002 in mono mode. Giving it approx. 800 watts. The box is 2 cubes after all displacement. For the port I doulble up a pc of 3/4" MDF and glued a pc of 4" pvc pipe through 1 layer and router a 1/2" radius on the top layer to make a homemade aeroport. The length overall of this port is 13". I don't believe I am right in thinking the tuning is at 32. Can someone double check me on this. Also am thinking about shortening the lenght of the port to get about a 35 hz tuning. This is just a temporary daily box for me to have something till it warms up. But I listen to all kinds of music so I needed some beat in …

I just received a phone call from Matt Borgardt at ID. Due to the fact that he is seriously ill, we will be unable to have the IASCA event on Jan 24th. The event will be rescheduled for some time in April. The next IASCA show will be February 15th at Beach Autosound in Huntington Beach, Ca. I apologize for any inconvenience this may cause any of you. Please try to spread the word so we don't have people driving in from out of town to show up at an empty parking lot. -Todd Woodworth

currently running a huge box with a fi q18 takes up the entire back seat of my truck. i love the output for the power i have and the low tuning, but it needs to come out for a carseat. i have a pair of tangband w8-740p's, single 4ohm 150wrms 8's. im thinking about building a box 1.75cu tuned to 39hz with 26.25sq of port , trying to get the most output possible. not sure how to design the box was thinking about trying a loaded horn thing like thumpper did with the icons. anyone with exsperience with these speakers or small truck boxes any imput of how i can get the most out of these 8's would be great. vehicle is 99 dakota x-cab.

I came across a thread on here where a guy cut slices into one side of a sheet of MDF and then he bent it into a tube! I can no longer find it and i wanted to get a better look at it because i was thinking of using this technique! Does anyone remember where this is? or does anyone remember seeing this? Please post a link to this thread! It would be greatly appreciated!!!!!!!!!! <<<<HAHAHA
