The challenge is how to ensure the uniformity of the speakers?

　　The biggest challenge faced by R&D engineers is how to ensure the uniformity of the speaker and eliminate resonance in the mid-high frequency. This is a compromise that has to be made in every speaker system (except for quality speakers). Other problems are cavity resonance and nonlinearity of the magnetic field.

　　Uniform motion stiffness means that acceleration from the voice coil is accurately translated into acceleration over the entire surface of the cone or dome; this results in a flat frequency response, fast impulse rise, low intermodulation distortion, and sound transparency sense.

　　Audiophiles often describe this type of sound as "fast," much to the consternation of engineers who rely on objective measurements, "How can the mid-woofer be fast? Because the crossover limits the pulse rise time, it is quite For 1/5 or even 1/10 of the tweeter, this is just like a phrase that diplomats often say "exchange opinions comprehensively and frankly", or exchange misunderstandings.

　　It can be said that both are right and both are wrong. What they actually talk about is different. What audiophiles hear is uniform cone motion; this phenomenon shows up in testing: no intermodulation distortion, flat frequency response, and clean impulse response.
