I AM
Is there any good sites which give you a step by step process about how to build a box? I know the dimensions(sorta) but like the exact stuff...like screw sizes and sealing process? and what not...
anywho, if i give an RE8 .75cu ft is that good? with about 140rms??

I dunno about the box size and power for the RE8's...
but as far as screws, it should be about 1" in length, so that the screw will go through 0.75" MDF.
As for sealing, make clean straight cuts, use a LOT of wood glue and when the glue dries (give it a few hours or so) use silicone (any kind, color doesn't matter ) at the seams for good measure.
I told someone to do this a long time back and it works.
When trying to smoothen silicone, apply saliva to your fingertips and work. It does wonders. Water doesn't work, saliva does.

ahh...ok these are the types of things i would like to know! i sorta thought that but never actually seen someone come out and say it....the boxes for the RE8's are trials before the XXX

how come winisd doesn't have RE subs there??

a bummer, ain't it?
search the internet for T/S parameters. The ones given are the essential numbers that winISD requires for calculations. Fill whatever you can and start seeing some amazing graph lines

This should help you get a basic understanding of begining box building...

****, wrote one in, but got erased...****...
ok, here I go again...
I presume you know how to make a new project, change box size and port frequency ( if you don't, just open new project, select pre-entered driver, number of drivers, ported or sealed)
Once you get your graph open, try opening a competitive sub, such as the e8A.44 to make direct comparisons. A lot of veterans will tell you that graphs don't mean squat, but to a newbie whodoesn't know how to read the graphs too, it does give me a rough idea of where the subs place in the field of so many different brands and models.
Assuming you're going ported, look at how different each drivers will respond at different frequencies. It is with this that you can choose on what frequency you would like to tune your ports to.
you got to input signal strength to see SPL curves and cone excursion. I pay a lot of attention to cone excursion and rear port velocity.
multiply xmax number by 2 to get peak to peak figures, then see where the point is reached. thereabouts would be your settings for a subsonic filter.
As for rear port velocity, some say 35m/s is the max, some say 40m/s. SOme even say that 25m/s is still audible. Whatever it is, if you try to have too large a port and minimize port noise, you will have to make very long ports. SOme of it can go up to numbers like 1000"!
That said, I don't really read (or can't read) the lines much. I look more at the peaks, compared to the same driver in a sealed box, as well as a similar driver in similar sized boxes to make judgements on how large my box will have to be and what frequency I want it to peak at.
I hope that has helped out somewhat

Any chance you can tell me what the "Pe" figure stands for, and if it would be screwing things up to not have it in the specs of my driver on a project? My port lengths are coming up longer than any side of the box, and i'm trying to figure out what I screwed up. This is for a slot port on a 2 cube (after displacement) single 12" box tuned to 29Hz.
Any help would be appreciated.
