Unlike conventional loudspeakers, all Mach models are completely free from crossovers or any equalization/correction elements. Each driver is a full-range unit, carefully engineered to deliver an unadulterated sound. The only exception is a subtle cut for the super tweeter, which cannot be called a crossover in the traditional sense, as it does not divide the audio signal into separate frequency ranges. By eliminating capacitive, inductive, or resistive components, the Mach 4 maintains a system impedance that closely matches the natural impedance of the free-air drivers. This ensures exceptional damping, stability, and a coherent, linear response.

Traditional crossovers often reduce the system’s minimal impedance dramatically—sometimes to a fraction of the nominal value—placing heavy demands on the amplifier. By contrast, the Mach 4 preserves an impedance extremely close to the driver’s own coil “Re,” providing an ideal environment for the amplifier to perform at its best. The result is a system with superior damping, minimal time distortion, and the absence of phase shifts, all of which contribute to extraordinary detail, speed, coherence, and spatiality.
