The SPM-435 is built with 4 drivers working in separate frequency ranges to minimize distortion. The result is a pure, balanced sound that covers the whole spectrum of human hearing. Two dynamic drivers handle bass and low-mid frequencies for rich bass reproduction, while balanced armature drivers provide precise high and smooth hi-mid frequencies.
