Features
A) Reflected waves inside box
The inside of the box is treated with a special coating to regulate reflected sound inside the box, and this enables faithful reproduction by canceling unnecessary distortion of box vibration.
B) Resonance of unit body
The magnetic circuit is fastened to control unnecessary vibration from the heavy field coil speaker when mounting the speaker to the box, and this suppresses normal mode vibration and ensures outstanding response.
C) Baffle and back plate resonance
A side bar is provided to curb vibration of the baffle and vibration of the side plate due to speaker back pressure, and normal mode vibration sound is completely suppressed. Also, a steel plate is provided on the box baffle back side to minimize the effect of woofer vibration on the box, and this reduces distortion due to vibration and ensures outstanding response.
D) Box bottom vibration
A steel plate is provided on the bottom side in the box to suppress vibration transmitted from the box to the speaker stand, ensuring faithful sound of the speaker system.
E) Duct resonance
Damping material (special damping resin) is provided at ducts to suppress duct vibration due to speaker back pressure, ensuring faithful sound of the speaker system.
F) Front baffle plate
A 42 mm thick baffle is used to ensure no effects even with large vibration amplitude of the woofer, and this enables high-fidelity reproduction.
