Interestingly, while the bass/mid amps provide 200 Watts of Class-D power, the tweeter amps provide 30 Watts of Class A/B. The discrepancy between bass/mid and tweeter amplifier power ratings arises partly because the tweeter is more sensitive than the bass/mid driver (so needs less power), and partly because headroom is required on the bass/mid amplifier to enable LF equalisation to be applied. The decision to use Class A/B for the tweeter was taken on sound quality grounds.
