[QUOTE="winkychevelle, post: 8615346, member: 611804"] it depends entirely on the sub. Some motor designs excel at dissipating heat others do not. Then there is the quality of the coil it's self. Low quality coils often use low quality adhesive to hold the windings to the former. These adhesive often time have lower failure temperatures than there more expensive counter parts. And whether it is an 18 or an 8 makes little difference 90% of the power handling comes from the motors ability to cool the coil and the suspensions ability to control the cones movement. Theoretically an 18 would have a lower mechanical ration than a 10 because the cone is heavier and thus harder to control, but designers understand that and adjust the design to perform similarly. Companies that often give bigger subs higher ratings usually do so because the coil size increases with the cone size. Others just lie for sales. And a few allow more power flow due to different basket designs changing the thermal flow of the motor itself [/QUOTE]
