Amazing idea "Uni-Core technology"
The drivers installed in the KC62 have two 16.5 cm calibers. By arranging these two units back to back and driving them in phase, they are designed to cancel each other's reaction forces and reduce the vibration and resonance of the cabinet (force scan selling technology).
16.5 cm caliber woofers are mounted back to backHowever, if you try to accommodate two drivers, the cabinet volume will inevitably increase. But to prevent that, the KC62 has some amazing ideas.
That is the "Uni-Core dual driver" technology that drives two diaphragms by incorporating two voice coils of different diameters into one magnet system without interfering with each other. By adopting this structure, the cabinet size can be reduced to one-third or less (to obtain the same performance) compared to the case of adopting two magnet systems.
In order to realize force scan selling, it is a prerequisite that the symmetry of the operation of the two units is maintained, but the KC62 maintains that symmetry by adjusting the winding length of the voice coil. It seems that it is.
Uni-Core technologyIn addition, the two voice coils are equipped with a gyro sensor and a sound collecting microphone, which senses the operating current in real time and feeds it back to the built-in DSP to significantly reduce harmonic distortion. The function is built-in.
backNamed the "Music Integrity Engine", this DSP has a variety of features, but the "Room Placement Equalization" feature is especially useful. The transmission characteristics of long-wavelength bass vary significantly depending on the size and dimensional ratio of the room, and the performance of the subwoofer is greatly affected by the location.
For example, if a subwoofer is placed in the corner of a room or near a wall, the bass range will rise due to the reflection of the wall, and there are many cases where it "bonts". In that case, if you set the "Room Placement Equalization" of this unit to
Other features of this feature are ROOM, CABINET, and APARTMENT modes. ROOM is a mode when placed sufficiently away from the wall, and flat characteristics can be obtained. CABINET is a mode that eliminates the muffled bass, assuming that it is installed in furniture such as a rack. APARTMENT is a mode provided in an apartment building to suppress sound leakage to the neighborhood, and an equalizer is set to cut the ultra-bass in the subsonic area.
Another interesting thing about the KC62 is the edge structure of the diaphragm. A bellows-like pleated design (P-Flex edge) is used to properly control the air pressure inside the cabinet while ensuring sufficient amplitude. It has a structure that suppresses distortion and is resistant to excessive input.
As mentioned earlier, the KC62 is a very compact subwoofer, but when you hold it in your hand, it's heavy. Aluminum casting that pursues rigidity and weighs 14 kg. A loosely rounded design is preferable, and there are two types of coloring, mineral white and carbon black. Because of its small size, it can be hidden in an inconspicuous place in the room, but the finish is very beautiful and it is important not to hesitate to set up the living room.
