The SPM-435 is built with 4 drivers working in separate frequency ranges to minimize distorsion. The result is a pure balanced sound which covers the whole spectrum of human hearing. 2 dynamic drivers are used for bass and low-medium frequencies for a rich bass reproduction. The balanced armature drivers provide precise high and smooth hi-mid frequencies.
