The entire range is way to bass heavy, it's not sub bass either.
Voicing refers to the way a speaker or system sounds, most companies have a particular voicing style, like JBL. A few years ago LG had MartinLogan co voice a system for them. A current example is "beats" they voice headphones and now laptops etc, it's not like they make the drivers but they do "voice" them to give their signature sound
