Knocks pictures off walls.. lol. It's honestly just a design theory I had. I'm infatuated with high output low distortion drivers. Just want to build something ****** that's musical. I'm sure adding some shorting rings would lower the le more(stabilize the curve abit) but it's already a expensive driver to build as is. Although the mag id rings aren't expensive and apparently they help stabilize le I need to test if it is worth it. I've never tested this theory before so I started off with a more typical build with no shorting rings. Although I really want to do a full copper sleve but that's going to cost a good deal more..
