It's pretty cool the more I use it the more things I find to use it for. Plus using this tool you can find out how your displacement affects tuning, I might try to take the magnet boot off and see it if slightly changes the Fb since airspace will increase.
I'm an audio nerd lol, but everyone can benefit from this tool.
Can't wait to use it at work
the more i learn about things in my EE classes the more i want this thing just to run around testing stuff lol
