[QUOTE="mat3833, post: 8800604, member: 587645"] Inductance is something I've had experience with outside the audio world. The drive motors(40hp servo motors) for the CNC bridge have to be measured yearly. Inductance, resistance, holding current, etc all get measured. If inductance gets too high Fanuc will no longer stand behind their accuracy claims for that particular axis. The rest of the metrics are mainly a health check on the windings. Speakers are complicated by nature. You have an electromagnetic suspension, a mechanical suspension and an air suspension all working together/against each other. The inductance value is only a small part of the equation. From my experience, the subs I've ran with lower inductance (TC-1000 15's, pro 5100 18's) always felt more accurate. The best way I can explain it is violently accurate. Even at lower volumes, kick drums Smack you in the chest, low frequency notes just move you, and pitch changes feel instant. The JBL W15 GTIs I ran were awesome, but they weren't snappy and accurate until I threw tons of power to them. I've ran a ton of different subs infinite baffle. That is pretty much the most demanding environment from a critical listening perspective. There isn't a box to help control the cone or alter the subs parameters. The suspension and motor do all the work and until now I haven't wanted to run anything else. If the sealed enclosure doesn't sound like I expect it too, I'm going to remove the back panel and run these subs in 31 cubic feet of "trunk baffle". Matt [/QUOTE]
