The T501 has an excitation type compression driver mounted on the vibration system.The front panel designed horn road short, suppressing exciting sounds on the auditory sense. Furthermore, in order to maximize the efficiency of the compression driver, Threefold's gunmetal equalizer and a teardrop type equalizer are adopted, and a high-frequency regeneration with a high efficiency of 20000 gauss and excitation type unique high-frequency characteristics It is realized.
