slot port

[bkolfo4]

There are multiple suggestions above - choose one.

Multiple ports - example: 2 ports that give a 45 Hz tuning, seal one up and the tuning changes to 35.

Build a smaller port that will insert inside the larger port (less port area with the same length = lower tuning)

Building a price to decrease the width of the slot port (Same idea as an insert).

These are the best options.

As far as the frequencies, 32-35 is good for daily, and the SPL should be a few Hz below the cars peak. You will have to figure that one out.

ya but my ? is do i build the box to the 33 hz port or the 45hz for spl? im new to box building but i know that the different ports will change the box volume. so what am i posed to do?

Port area 1 x length 1 = Port area 2 x length 2 you can do two ports that tune differently but have the same volume, in any case probably you want less net volume in the SPL setup.
