1.75 x what? area requires two dimensions.

port area has nothing to do with the sub. the cubic ft. of the box determines port area. for a slot port, in 1.75, you need 18-24 sq. inches. 1/2 that if you use aero ports.

Port area does need to be figured in relation to the x-max of the sub though, if you dont consider it, port noise could become an issue.

1.75 width by 24 inches long..tuned to 36 is the current set-up..my question is is the enclosure to small along with port lenght and width

1.75 x ? x 24, a port has a width, height, and a length.

you have plenty of port area.

x 2 And your tuning is closer to 32-34Hz, being a slot port.

would widening the slot width tune higher or lower?wondering if it would make a deeper bass note

you'll change tuning in a big way, and would have too much port area. leave it alone.
