"Box design help"

[matt3477]

I have the materials already sheets of plywood in my attic. Only need box schematics or ideas. One 12" sounds like a good idea, for that price sounds good also, is it 2ohm? I have a 600x5 Rockford fosgate amp, 200@4ohm and 300@2ohm for the subwoofer. IF possible with the dimensions I gave in my first post, I'm trying to go for spl.

Basically sum it all up, need a nice box for the specs I gave and am open to ideas that sub and a nice box design sounds good to me.

I would take the SQ sub over the RF personally, also if you are shooting for spl you can gear towards that but I doubt 300 watts will get you there. The SQ sub is available in dual 4 which can be wired to 2 ohms. I can definitely say that we will be better able to help you if we know your budget and skill level as well.

Edited: Because I was bored.

Yes OP you can still save $3 and get a sub that's far more adequate for high output:

It will handle 800W RMS no problem, it can be placed in a 16.25x37.25x12 box

$100 budget.

Ok so that sub. Now I still need a dox design and my skill set? Gotta learn somewhere aha. This will be my first box. Just would like some schematics and sq route would be fine.

Thanks.

For that sub HDS 212 you could do this box, really made simple to build just sand to round some edges on the port as shown in the figure, free airspace in front of the port 2 1/2", subsonic filter to 28Hz, (assuming that you have a trunk car: check that the box will go through the trunk opening before cutting any wood, build a cardboard dummy box to test fit):

And there you go! And later on when you get a bigger sub amp you can boost your output considerably with a simple upgrade.

Looks good! Thanks!
