Does anybody know a simple to way to calculate or estimate the roll off of a slot load? I feel like I have seen this mentioned before but I can't find the information.

Basically I am looking to use a slot load on an 8" midbass. The midbass will play from 80-300hz. How deep can I make the slot before I run into issues at 300hz? Any other considerations that will impact the desired frequency range?

Thanks for the replies.

The reason I am asking this is because I have an application where I need my output to come from a certain position. But, the drivers cannot fit there. So the idea was to use a slot to create a phantom source of sorts.

This is for midbass. I figured out how to model this in Hornresp. The interesting aspect is that it seems to add to group delay, if the sims are correct.
