Very VERY entertaining and informative. I actually have a storage closet in my theater that is under the stairwell so it has an irregular shape like you're describing and I was VERY curious as to how to measure internal volume for "tuning" of it if I decided to turn it into an Infinite Baffle setup! So thank you so so much for posting this! I'm looking forward to your slot port video as I'm thinking about porting Project Smol Boi and tuning it to 15Hz and I want to do that with a slot port. So before I do something that requires a "rebuild", I'll wait for your video to drop so I can take all of your tips, tricks, and information, and use THAT to perfect the tuning! Epic video series, I love it!
