I have 2 AudioBahn AW120Q Excursion 12's (500 RMS each) I was wondering what kind of box I need to build to get the most out of my subs?? (Sealed,Ported,or Bandpass)?? And how big??or what size?

If you want primarily sound quality go sealed. If you want them to be loud go ported. If you want them to basically sound like crap go bandpass. They should have the box specs in the manual somewhere, just look for something that says "recommended box size" or something like that. The smaller figure should be for sealed and the larger for ported. Once you do that, figure up the dimensions of the box you want, find the total area (length x width x height) and divide it that number by 1728. The final number will be how many ft^3 the box is...roughly...there is a lot more to building ported boxes.

For example...if your box measures 14" tall, 14" wide and 15" deep, figure it like this...

14x14x15=2940.......then divide 2940 by 1728.....

2940/1728=1.701388...

therefore your box would be 1.7 ft^3

hope that made at least a little sense.

1.7 ft^3 before speaker and port displacement ... have to take those into account, too.

yeah thats why i said ...roughly... at the end of the paragaph.
