With their asymmetrical design, the Estelon Model YB speakers are a prime example of a functional design approach. The cabinets were moulded from a composite material and shaped to optimise sound quality. The placement of the drivers in the cabinet is also well thought out: the mid-woofer is positioned above the beryllium driver to minimise sonic reflections from the floor. The wider speaker base accommodates the bass driver with aluminium diaphragm. Since the woofers are angled towards each other, they can be placed close to a wall even in smaller rooms without having to cope with overlapping sound.
