View Full Version : When is a box TOO big?

10-17-2005, 11:10 PM
Ok, story. I'm buying a 10" Dual XS10 or something from BB for $13 new. I want to build a big box for it and make it as loud as i possibly can, before then blowing it in an insane way.

I have WinISD (anyone got a place to get BBP?), how do i figure out on my own what figures to look at on the box to see where it would be the loudest? I'm talking cu ft.

Obviously it doesnt need a HUGE box, but what goes wrong when the box is too big? Over excursion? Is that it? I just want to be able to go into WinISD and make a box on there that'll be loud as hell for this sub, without having to look at reccomended airspace and all that.

a $13 dual cant get loud!!!

please dont get a dual

oh, im getting one.

I guess I'm trying to say maybe not specifically BIG, but say going from the reccomended airspace, when does it stop sounding good and what computed figure tells you that?

too big=bottoming out?

Not necesarily, IB can be done with certain drivers

Thanks guys, I'm well aware that Dual is crap. You guys are really providing some useful information in telling me that a $13 subwoofer is crap.

I'm doing it for fun. And if I blow a $13 sub? Who the hell cares about it.

It depends on how much power you will be feeding it. If its too big, it can reach over-excursion too quickly if you have enough power.

Come on guys, it's fun to destroy things. I'm with ya brother man. As was said before over excursion will become a problem at some point ( I'm no enlcosure expert, never claimed to be either ) It's even more fun to try and destroy something that just won't die :D Did the same thing many moons ago with some good old Dr. Crankenstein's. The d@mn things wouldn't die....... :)

i'm building a 5 cu ft box (after displacement) tuned to 29 with 95 sq in of port.

it should be fun, not expecting much, just something to do

I had the same idea before, Sort of. I aquired 10 inch volfehag I dont know which one but it was shiny red. It was rated at 350 watts I think. I put it in a huge box somwhere around 3.5 cubes.It was a box for a 15 but i old schooled it and screwed a piece of 3/4 over the holes then cut a new ones on the back it was an old box. I hooked a jl 1000/1 to it turned it a lilttle over 1/2 way and it got about 15 seconds into the bass line of Triple 6 late nite tip and pop. It melted the shiny red sub you couldnt even move it anymore.
