The speakers are disposed in a generally ascending arrangement with the bass speaker occupying the bottom position, the super-tweeter speaker mounted immediately above the bass speaker, the tweeter speaker mounted immediately above the super-tweeter speaker and the midrange speaker mounted above the tweeter speaker.
