Simple bass guitar speaker cabinet tuning

In this video, I demonstrate a simple technique for checking the tuning of a bass guitar speaker cabinet, and adjusting port or slot size to optimize your speaker's performance to be as efficient as possible on your lowest note. I can't guarantee the accuracy of the information in this video nor your results, but I have done this more than once successfully. Of course if your cabinet is under warranty, I would not suggest you modify it in any way, or you will likely be voiding the warranty. Please add any additional information that is relevant in the comments below, and feel free to ask questions if you have any. Thanks, and I wish for a very happy 2023 for all of you!
