Dynamics In A Speaker

Another key, more practical, and sometimes overlooked, design aspect when it comes to dynamics are the crossovers. Passive crossovers typically rob considerable amp power - most especially in the dynamic peaks which can be rather blunted and compressed. Removing passive crossovers and going active can be an ear-opening experience. Another option would be to either look at speakers that are known to employ rather high quality passive parts (perhaps the majority actually don't), or consider investigating how to upgrade with better quality parts. 

besides what Duke (audiokinesis) wrote about the importance of not putting the drivers into mechanical compression, I think that ivan_nosnibor brings up an important point - cross-overs.
For me the most dynamic speakers are time-coherent speakers that use a 1st-order internal x-over. Not saying that an external x-over would have been better but I’ve not heard a time-coherent speaker w/ an external x-over so I cannot comment.
Assuming that the speaker designer chooses the drivers correctly so as to not induce mechanical compression, dynamics in speaker comes from its actual design....

How about in an electrostatic speaker, same question? Cheers,

Spencer, did you manage to get in contact with somebody for your ESLs? sorry i realize it's off-topic.....  

Isn't sensitivity/efficiency a huge factor in a speaker's perceived dynamicism (is that a word ;-?)?
