[QUOTE="sundownz, post: 3428382, member: 549523"] Indeed, all true at rest by T/S specs. I am wondering about dynamic parameters w/ power applied. My thought is that XBL^2 would be more efficient with greater greater power applied vs, lets say, a sub with a higher at rest BL -- something like a DD 9500 series. Say... we used the same magnet stack and changed the top plate around to keep the same coil, only made it XBL^2. Maybe I'll fool around with that a bit later and see what happens! Any predictions? My initial thought is that the XBL^2 design would likely handle itself much better at 15mm+ of travel, likely having much higher BL than the "regular" motor (I'll use something big like the DD 9500 motor) at levels of travel that high. It's "dynamic sensitivity" so to speak, or if you measured T/S with the cone sitting @ 15mm of x-max and calculated sensitivity... would probably be higher. What do you think?
