Although a 594A driver tells delicately, without leaving expression of a delicate sound, the speed of the feeling of energy and sound is not an ordinary thing. All woofer does not catch up. It will use up to the cutoff frequency of a phon. If it is likely to become a problem about reflective generating, it will adjust by the extract tension later. Since the frequency characteristic near 200Hz crossing is already surveyed, the characteristic of woofer is united with this. I want to obtain with reference to the clause of this frequency characteristic measurement of HP about the survey characteristic. The network circuit diagram was as follows.
However, this method using a reactor is not common. 200Hz or less and 12 dB/Oct -- it is effective only when cutting steeply on low frequency called the above. 300Hz goes wrong. A reason is in the characteristic of man's ear. Since man's ear still identifies sound fairly sharply in nearly 300Hz, deception is difficult. If it becomes the crossing of 200Hz or less and 12 dB/Oct or more truly, an ear will become the peculiarity of the sound of a iron core reactor unable to be able to identify a difference easily. If it becomes like this, it will be called the influence of a difference of the difference of the material of in DAKUTA, or this discernment will become sweet. Compared with this, discernment of the difference of the corssover characteristic by the difference of direct-current resistance is fully severe. It is the strategy using the characteristic of this human being's nonlinear ear. It is better for 10u of C4 to be indispensable when hearing the vocal which cleared up although the slope was determined, but to remove, when asking for the reality of a piano. It has changed into the state where it attached usually. Refer to the item of other networks of Book HP for other details. A lower figure is a survey frequency characteristic including the characteristic of the room at the time of performing a -6dB ATTE nation to 594A. The level of woofer and a compression driver is correct in general.
