The product is a set of 6 white units, the second from the right in the first photo. Mr. Mai Denchu and those who have used 5 million yen worth of sound tuning materials were astonished by just two units. For those who have tried audio boards, sound-absorbing materials, etc., and are not satisfied with the results, this will put an end to sound absorption. It reduces the muddiness and standing waves of low frequencies, and has an amazing sound quality improvement effect. Audio manufacturers and retailers sell expensive products that make you expect results, with the goal of increasing sales and profits. If problems are solved with such inexpensive sound tuning boxes, it won't be good for business. Therefore, they recommend trying something, such as products with uneven, fluffy sound absorption/reflection, products with sound-absorbing materials in the holes of the board, or fiber-based sound-absorbing materials. Then, it's a done deal. Only the mid-high frequencies are reduced, and the sound localization deteriorates, and the problem is not solved. Then they recommend another product, and if that doesn't improve things, they recommend yet another product. Before you know it, you're covered in 3-5 types of sound-absorbing and sound-tuning materials. You want to listen to the recorded sound, but you can't absorb the mid-low frequencies, and the more you install sound-absorbing materials that only absorb mid-high frequencies, the more it's like listening to the TV with a blanket over your head. You get more and more muddy, hazy, and rumbling low frequencies. Then you get sucked into the quagmire, thinking you have to change cables, amplifiers, or even speakers. The problem is that the standing waves and echoes of the low-mid frequencies, which have low directivity, are modulating the high-mid frequencies, which have high directivity. If you don't improve this, you won't get close to the recorded sound for life, no matter how expensive the equipment or how much you spend on sound-absorbing materials. It's like taking stomach medicine when you have a bad liver; the problem won't be solved. New In HIBIKI, with a porous patented sound-absorbing material with a surface area of 360,000 m2 per unit, solves these sound problems all at once. 12 x 12 x 52 cm, approx. 1100g It can be easily installed on walls. "It's like bringing a concert hall right in front of you." "It's like being able to go between the instruments on stage." "It's frightening to think about not having met In HIBIKI." Thousands of units sold promise to dramatically change the value of your musical life. From the left in the photo: brick, beige, white, and chocolate, each with 6 units, and a set of 4 units for 170,000 yen are also available.
