Do you think I will get any port noise from a port that is about 1"x13"x10" deep?

lol, it would help if you told us more about the box...like what's the net volume?

The net volume is around 2.25 tuned to 35hz. With a ia 187 12". Need to know anything else?

Who designed it? That's nowhere near enough port area...without knowing what your specific woofer needs, the general rule of thumb is about 14-16 square inches of port area per cubic foot net. You have 13 square inches of port for 2.25 cubes. Port needs to be bigger and more proportional.

Ok that is not exact, it is roughly 13 9/16x1 3/16, or something like that I remember it was 15.89 for the port area. I have all the nesurements at home, I am at work right now and I was trying to get an idea if there would be any port noise? And I was told by zierbox that the shape of the port didn't matter just the area, but I know if you have alot of air moving thru a small space you get noise.

Right now it really doesn't matter what the exact dimensions of the port are because it's not even close to being big enough. You need 14-16 square inches PER CUBE. You hace 2.5 cubes so you need a minimum of 35 square inches of port area.
