Hey what's up everyone? I know that I had said that I would have a pair of Brahmas for this spring but I have yet to hear anyhting about them comming off backorder. I got a sweet deal on 2 RE SX 15's. I will be using these subs for both daily driving and SPL competition so I want to tune it to about 38-40hz. I think the box should be 7.0ft^3 but I'm just not sure about the port size. I would like to put the port in the center of the box in between the two subs rather than on the side. The box will be rear- firing. If someone could help me out with this I'd really appreciate it.

i think the box should be a little bigger, like 8 cubes, 4 for each sub. ( did you rember to add volume for port and woofer displacement) i know for a 4 cube box for one 15"sx the port is:
26.5 x 4 =45 hz
26.5 x 13 = 32 hz
that was from a RE dealer, using Bass box pro 6 (or something like that)
