KOTOBUKI Onkaisoku KP-01 (Plum color) / 1 sheet [Pre-order item]

Acoustic panels that absorb low frequencies - Realizing the original brilliance of sound clearly - "Sound Quick"

■The diamond-shaped opening makes use of the same material used in the soundproofing walls of Shinkansen bullet trains and spacecraft, and the aluminum sintered plate efficiently absorbs low frequencies.This eliminates the muddy sound used in spacecraft, and produces clear bass tones.
■Audio-like To bring out the true essence of music, the surface area of the sound-absorbing adjustment part is not increased in the mid-to-high range in order to make the most of the natural materials as much as possible, but the low range is given a surface structure that allows for full sound absorption adjustment. As a result, an edge is created in the low range, and by controlling the low range, information in the mid-to-high range comes out clearly. Beyond that, the sound field space is also reproduced.
■Infinitely wide range of sound creation possibilities (the sound changes depending on the orientation and placement of the two diamonds)
Placing two of them on the bottom lowers the center of gravity of the low frequencies, while placing two on the top provides a balanced sound from low to mid- and high frequencies. The back of the speaker creates space. The sides of the speaker allow you to adjust the distance from the speaker to process the low frequencies or balance the mid- and high-frequency ranges.

・"Calm" is the ultimate sound-absorbing material, also used in the soundproof walls of Shinkansen bullet trains.
The material we use, Calm, has the highest sound absorption rate and durability, eliminating reflected sound that degrades sound quality in the room.
Aluminum is known for being easy to process and install, environmentally friendly and recyclable.

・Calm is a porous plate made by molding aluminum powder using a unique sintering method, which allows us to produce a porous plate with a high porosity that was previously unthinkable. This is NDC Calm, the world's only revolutionary sound-absorbing material.
By changing the air thickness behind the Calm (the gap between the Calm and the insulating plate), sound absorption at the target frequency can be controlled from low to high frequencies. Surface painting and curved surface processing are possible without weakening the sound absorption effect, making it suitable for a variety of applications that were difficult with conventional sound-absorbing materials.

- Faithfully reproduces the resonance and sense of speed of the sound!!
By using a sheet with the same purity as the 99.99999% pure aluminum material used as heat shielding material in spacecraft and space suits, the natural vibration coefficient of aluminum and sound work well together to create a sense of resonance and speed in the sound.
