ONGOKUSHIN High Spec Insulator KS-01

High density silicone insulator which is used to be used for a drum set insulation material. Kotobuki engineered this material to make a high performance audio insulator. This can be used for a base or top of a speaker box and amplifiers, and many more applications you name it!

AWRD2018_edited.png

When sandwiched your equipment or device with this insulators, the effect will be doubled. Since the insulator also en sandwiched your equipment or device with this insulators, the effect will be doubled. Since the insulator absorbs unnecessary vibration generated from speakers, pre and power amplifiers, CD player, and analog player, it will entirely shut out the vibration sources.

 

  • improve S/N and resolution

  • improve distortion by which clear audio texture will come out

  • improve audio sound density

  • low frequency range supporting stage will be set to clearly low

  • low level sound that have not been noticed will stand out

  • non slippery surface will firmly support equipment

  • withstand up to 22k lbs

Note: Discoloration may occur by heat generated from equipment when used long, which will not affect performance.
