Model D

The speaker the company was founded to build, and still its largest: 2.06 m and 174 kg of aluminium frame with four woofers, two midranges and an AMT hanging in open air, radiating from front and back with no cabinet to colour either wave. Each baffle is milled from solid blocks over more than 170 hours of machining. The crossover is unusual even by the brand's standards — the woofers roll off at 150 Hz while the midranges only come in at 250 Hz, both computed in the processor, with 2.5 kHz to the tweeter.
