The tweeter uses tapering tube loading, first used in the original Nautilus. This ensures far greater absorption of unwanted radiation away from the rear of the diaphragm and results in a cleaner, more focussed and natural high frequency sound. The bass/midrange driver uses a cone of woven glass fibre, which functions in a similar fashion to Kevlar.

The crossover components use air core inductors for lowest distortion and plastic film capacitors for minimal signal degradation.

The front baffle is moulded in inert micra filled polypropylene, which has a subtly curved outline and is dimpled to echo the theme of flowport at the back; itself elegantly combined with easy-access terminal panel that can accept all common terminations.
