So I was told to build a box with 3 2.75" x 2.75" x 20"(deep) ports...

I ended up making one wiiide deep one. ****, right? I think so.

Here she is, in all of her hot and unsandedness and unholiness.

When I get the sub I'll cut the 13.98" hole with a jig and paint it black.

;-D

Soliddddddd. And... my port is going to work beautifully, thanks.

ahah ;-P

that port is WAY too skinny :( nor does it look like its enough port area for that box.

Who the hell told you to do that?

i know the ports like wat 1" wide? you will get MUCHO MUCHO port noise.

He wanted me to ask what port noise is?

For a box that size, I would gather a lot more port area will be needed. What sub is going in? Also having a port with a larger ratio of 1:8 is a bad Idea. There will be increased port noise about 90% of the time.

From my experience, you're going to need to do it over.

Okay, seriously, what is port noise?

And I'm putting a 15" RL-p in it on 850 watts.

My cousin and I did this in about 30 minutes. I'm sure we could remove the front piece and cut an extra inch to make the port wider if need be.

im confused as to y you build a ported enclosure without knowing anything about port tuning...

Are you serious? Noise that comes from the port...

When you have a lot of air being pushed threw a small space, turbulence is created and you will get a rushing flop/whistle sound. Basically it sounds like chit.

And the port is way to small for an RL-p 15"

You need at least 35 square inches of port area in a 1:8 ratio or smaller.

Also what is it tuned to?

I had someone set me up with ports for THIS box that would tune my port(s) to 28 hz.

He told me to make three 2.75" x 2.75" ports that were 20" long.

I made one 18.75" x 1.8" port that was 20" long.

Same volume.

I'm still proud, if it whistles then I can be special.

"You need at least 35 square inches of port area in a 1:8 ratio or smaller."

How do I go about making 35 SQUARE inches of port area?

I feel bad for the man.

Maybe you should pm one of the people on here and ask if they can design you a ported box for a small fee. If you dont know much about ported boxes i wouldnt suggest just throwing the wood together and hoping it sounds good, because they can be tricky if you dont know what your doing.

10 inches tall, 3.5" wide, 10 x 3.5 = 35 in^2. it is the cross sectional area of the port. I would go for a port 15" x 3" at least and flare the port on both ends and round the bend in it.

I'm sorry, but what do you mean by 'flare the port on both ends'? I do understand how to round the bend.

did he even make the port boards on the inside??...or did he just cut the last board short and call it a "port"???

flakko
08-23-2005, 02:16 AM
what I would do is just seal off the port, take the internal volume again and stick some aero ports in there....

drzenitram
08-23-2005, 02:32 AM
Yes I made port boards.


What are aero ports?

kuijo

PVC pipe. Round ports. 35sq inches of port area might be difficult to get though.

flakko
08-23-2005, 02:35 AM
ya thats wat basically a "round ported" box is. a sealed box with ports in it much eisier to calculate than a slotted port

Let me ask this first, Do you even want our help to fix it? If not enjoy I guess...

trigger, I want your help to fix it, but when people try to make me look like an idiot I don't appreciate it.

I'm here to learn, I never claimed to be an expert, much less GOOD.

I have never built a box before in my life. I just don't want to pay 200 dollars for one that's tuned correctly.

tRiGgEr

You can build a proper one with one sheet of MDF. Give me the dimmensions of that box and I can give you proper slot port dimmensions. If you still wish to give it a try to see what we are talking about, go ahead. I'm sure after hearing the port noise you will be willing to give the box a new build.

PVC pipe. Round ports. 35sq inches of port area might be difficult to get though.with aeroports, he won't need all of that port area because of the flare. He could just use 2 of them.

drzenitram
08-23-2005, 11:01 PM
Okay, I don't think I'm understanding this port area thing. How will I flare PVC? I mean, do I just sand the ends?

Alright... and will I need two 4 inch ports to tune my box to 28 hz(ish)?

I doubt them aeroports are long enough to tune your box that low with 2 of em.

flakko
08-24-2005, 10:45 PM
ya just use one. the more ports you add the longer they get. SOmething which i find odd.

the box you built looks nice, the port does seem kind of small in higth, altho its is wide, the hight might give you that air rushing in and out noise.

here are 3 nice link to help you calculate the box and port dimensions.
there are like a billion of these links on how to build ported, sealed, blah, blah enclosures.

remember Google (http://www.google.com/search?hl=en&q=how+to+build+a+subwoofer+enclosure%3F) is your friend use it wisely.

I like em better than my slot ported box.

he would have to run them on the side I think to get 28hz and would need to buy an extra 4" pvc pipe to run the length.


What made you decide on 28hz? just out of curiosity.

Reccomended by the RL-p website.

tRiGgEr
08-25-2005, 01:08 PM
It's already taken care of. He is going to try the box out and if he gets port noise, He will build a better suited box.

Reccomended by the RL-p website. IF you listen to rap at all you might want to consider 35hz tuning.

"You need at least 35 square inches of port area in a 1:8 ratio or smaller."

How do I go about making 35 SQUARE inches of port area?

Tuning is determined by NET Volume, Cross-sectional AREA of the port, and Length of the port.

If you are interested, send me a PM with the max Dimensions you can fit in your vehicle. Also what type of vehicle.

I'll design you a perfect ported enclosure, with the needed volume, port area, and tuning. I include all specs, a detailed cut-sheet listing the exact size of all pieces needed to build the box, and a sketch. It's $10 via paypal, I've got plenty of references as well. :)

28 hz would be a nice tuning for the RL-p. :)
