New Box
 

I finally get shop class, and we are making our projects. We are going to be starting towards the end of next week. I want to make my box 2ft deep, 14.5 inches high, and 37.5 across. Im going to put my 2 10" pyle woofers in it( i know they are crappy), but i dont know if i should slot the box or make it a sealed box. And if its slotted or sealed if i should separate the subs from each other. I also got some plexiglass for peices on the back so that you can see the rear of the subs. Im gonna put neon lights inside of it too.
Ne sugestions???

its really up to you and your preference for music. Do you know the difference between the two? are you ready to tune the box for the subs? The box should be designed with the driver in mind, is it?

I like all kinds of music and since we have like 3 weeks to do our projects i could definately take the time to tune it. I've really been wanting to try a slotted box, but i don't know how to tune it. Would there b a calculator or something that i use to help me?
What do you mean when you say "The box should be designed with the driver in mind, is it?" do you mean like the power or what?

He means Tunign frequency of your sub, fs, and did you look at what your sub likes in terms of boxes ?.. and what size to build them.. you just can't stat building a box and tune it after.. you need to integrate this into your box design

ok, would i need to make 2 diff boxes or could i just have 1 port for both of the subs?

The tuning frequency of my sub is 26.9
And i couldnt find many boxes that had my subs in them.
would the Vas (cuft) help at all? cause that is 2.394 cuft.
http://www.pyleaudio.com/manuals/PL1090BL-1290BL-1590BL.pdf ---Thats the link to the manual its the 10 in subs. So would i need 2.394 per sub or if i put the 2 together could i use that or would i have to double it?

ok i found out a bunch of calculations for the box.
what is a good frequency for rock music?
I worked out that The box in the pic/diagram thing would work out to 26.9 htz, but i don't know if thats a good tuning frequency for rock

Well someone tell me im wrong but i can tell you that tuning it to 26 would be too low, a typical daily driver is typically between 30-35. If your sub suggests 2.394cu per sub then it would be best to build it to that/start testing the driver from there. If you want to get more complex (meaning you need to know the Thiele/Small specs of the sub) you could try and use some free programs such as WinISD to see how the sub will sound at that volume and tuning frequency. These program will not provide the exact results as real life, but you can see your loses and gains at each tuning freq. Try downloading it and read the help file it will guide you through the process of getting the results you want. If you listen to alot of rock I think sealed would be a good choice.

To get my subs in the 30-35 frequency range i would have to go with 7cubic feet on the inside, but would that be too much for my subs to handle? they are recomended liek 2.3 ft per sub:dunno:

You build to the size that you want (what the sub works best in) and tune it to that... your port size affects your tuning

i decided to build a sealed box. So would too many cubic feet inside the box hurt the subs?

It wont hurt your subs but it you will loose bass in certain frequencys, check this site out: http://www.diysubwoofers.org/faq.htm this will explain it for you, you should build the box to what the manufacture suggests.

haha pyle is soo shitty i cant find ne thing on what size to build it

all i can suggest it try winisd, like i previously posted.. the only other option is to build a generic box..

ya i have been using it and it came out with 7cubic feet to tune it to 35hz so the box's demensions would have to be 37.5X 15X 26 inches

Interesting driver....the Fs of 26.9hz is pretty low for a 10" sub...having said that.....

Tried it in a couple of different box programs and the verdict seems to be to stay sealed. That figure of 2.394cuft is the VAS of the driver, not a recommended enclosure size. The peak in the response curve for the sealed box at 1 to 2 cuft/sub is bigger than some I've seen in ported models for other subs. In the interest of keeping it listenable (and having it fit in something smaller than my van.....:laugh: ) I would stick to a sealed 6cuft box. The curve is still there, but it's a lot flatter than the smaller box, and the -3db down point of 28hz is very low.

It sounds like you have lots of space in the trunk, so.....36"w X 14"h X 22"d gets you close and a couple of braces to stop any panel flex will fill in the rest.

Watch your power, with that much air behind them it will be relatively easy to over-drive the subs.

Let us know what you decide to do, I'm curious to hear what your results are like......nothing like cutting up some MDF for an over-the-top box for some off-brand subs......:smilie_da

HTH

Get one good 10", throw the Piles of crap off a cliff.

Well i finally got time to work on my box and an amp rack so here are the pics. I shortened the box so it would fit better. and made the amp rack so i could get the spare out if i need to. I still need to put the bamboo on the front and hook everything up + i want to put a light behind the amp and on shining onto the front of it im thinking red. I already have blue ones on the inside.

Does ne one have ne ideas for lighting? i want a different color than blue since i have blue on the inside of my box. I was thinking red. and then when i get another amp for the other side i was thinking green for it.Ne Suggestions?

dont put lights in it
