It is hard to follow your post there. So far this is what I got out of it.

You want more lowerend bass.

Your enclosure is

15 high

40 wide

20 deep

Your port I'm not sure on. Perhaps pictures would help better understand? It sounds like your saying it is 15 x 4 and around 13" long. However if the enclosure is 15 high how is your port that high?

How are your amp filters. Subsonic?

Assuming that is all correct your tuned in the mid 40s. Is it just a basic slot port design? Odds are you need to rebuild the enclosure based on your application and needs.

[kramer_212 10+ year member]

that could be one problem i also have the 13.5s though so maybe around 34hz should whats your port length?.....could also be a number of things like amp settings stereo settings wire gauge etc.
