KRIPTON spike receiver insulator IS-HR3. Thank you. High-performance insulator with a hybrid construction of "Neophaed" carbon matrix three-layer material and stainless steel material, which is highly regarded for its high sound quality. The "Neophaed" carbon matrix three-layer material speeds up the sound velocity of vibrations with carbon materials attached to the top and bottom, propagates them at high speed as surface waves (transverse waves), exchanges the energy with Neophaed for heat, and smoothly absorbs the vibrations. This damping characteristic shows a clear difference when measured compared to conventional materials. ● Compatible with spike receivers Can also be used with large floor-standing speakers with spike legs ● Uses the ultimate non-slip "O-ring" Special silicone rubber O-rings are embedded in the top and bottom to achieve the ultimate non-slip effect, especially the adhesion to the bottom is outstanding. Surface panel "Neophaed" carbon matrix three-layer material Body stainless steel Non-slip special silicone rubber O-ring Size (outer diameter) 40.0Φ x (height) 11mm Weight 95g/piece Set of 4 HR hybrid insulators that realize high-resolution sound quality improvement. - Brand: KRIPTON - Model name: IS-HR3 - Type: HR hybrid insulator - Country of manufacture: Japan - Quantity: Set of 4 Thank you for viewing.
