I'm not opposed to it I'd actually prefer it I just don't have the space for it lol.

Thanks for the input man! I might be able to get the port area up to about 140 idk about 160 I'll play with it tonight when I get off work. I think with the 120 it's about 13.8 port area per cubic foot. In your experience would it be louder to have a port going across the bottom of the box or up and down on the passanger side?

It's the same brand..

I have not built the box for the xs yet I have the box designed for them however. It's about 8.5 cubic foot net. Tuned at 33hertz with 120 sq in of port

I currently have 4 sundown x 12s and have the opportunity of switching them out for 2 zv4 12s. The zv4s would be a little bit better for space.. Either would be ran on a crescendo 5500 @.5. What would you go with?
