A speaker that succeeds with bass-driven electronica requires greater dynamic range, sub bass extension and mid bass slam than a design intended for music made exclusively by acoustic instruments. Many speakers that are perfectly adequate for other genres are incapable of playing hip hop or electronica in a way that is as satisfying as a well implemented car audio installation. Klipsch la Scala are a prime example of a fundamentally flawed design that censors any sub bass. Such a speaker may meet the audiophile definition of dynamic, but this fails to capture the need for fast, weighty and extended bass capable speakers that can do justice to bass-driven electronica and hip hop. For me dynamic is also a descriptor of whether a speaker can energise a room into the sub 20hz zone without ’one note’ colourations.
My personal system goal is to recreate the effect of a powerful dance pa of the Richard Long variety, playing in a large warehouse to a thousand plus people.
That’s why i use Focal speakers and Boulder power amps. Ime no valve power amp can achieve the necessary ’fear factor’ you get from plumbing the depths with a big rig in a big room.
If you strictly adhere to a definition of dynamics that excludes this, i submit that most punters would disagree.
