[QUOTE="ciaonzo, post: 8654796, member: 607015"] You can't bottom out a tweeter voice coil because of how thick the magnet is below the top plate. I put a picture below to help with this. Most tweeters have a voice coil that is the same height or slightly less than the height of the top plate. The top plate and the coil are not very tall, only a few millimeters. The voice coil former is usually much taller by comparison and on top of that is where the dome and surround junction occurs. The allowable stroke would be limited by the former height and surround width so if there's any amount of width, you can actually produce a pretty impressive physical stroke. The stroke is not always clean but if it is, you can choose between playing low frequencies (800Hz to 1500Hz) at low power levels, or playing normal frequencies (2kHz and above) with higher output and better dynamics. There are a few tweeters that can actually do both with very impressive freedom from thermal compression or IM distortion being generated from the dome moving back and forth. The ones pictured above and below are in that category. It's all in the motor and suspension, just like any other driver. [ATTACH]845._xfImport[/ATTACH] [/QUOTE]
