[QUOTE="djdilliodon!, post: 8870290, member: 684299"] That is mechanical movement, not linear. The mathematical calculation is the best way, that is the coil still in the gap (some may add 10-15%). Mechanical movement is when it comes to damage (coil hitting the backplate). Many use this spec along with peak to peak to make a sub appear to have a lot of xmax. The data sheet that shows xmax at 10.4mm may be accurate depending on how thick the top plate is. Looking at the coil again, the 2.25” is the actual full length of coil, not the windings so that spec is probably accurate. The 10.4mm is also mentioned on partsexpress as well. [/QUOTE]
