It’s obvious that a few here have never really listened to Rock, otherwise they would not be recommending Vandersteen, Volti and other speakers that were voiced with Classical and Jazz.
This is nonsense. Speakers are not 'voiced' using a certain form of music, not if there is a competent designer involved! They may prefer a certain genre, but that won't influence the design for the reasons I presented earlier.
Inefficient speakers struggle because the have thermal compression associated with the voice coil of the drivers involved. It hurts them with any form of music so isn't rock specific.
