Like all the speaker drivers in the K2 Power M range, 3 KM is fitted with Focal's iconic aramid fibre K2 sandwich cone. And for an even bigger performance, Focal's engineers have combined it with their famous ‘M’-profile. This shape of cone offers better frequency response and better sound dispersion, and reduces speaker driver depth. Attributes that go hand-in-hand with the power and dynamics delivered by the K2 cone. Thanks to this 3 inch (80mm) speaker driver, your system delivers faultless musical and pure, high-fidelity sound to provide the ultimate listening pleasure.
