XL Series: Shelf: Like CSR and ASRIII shelves with built-in honeycomb core, the XL shelf board also provides high vibration dampening effects like an audio board. The internal vibration sheet converts vibrating energy into thermal energy for a dampening effect, creating rich sound and core sounds that are close to top class ■ Adopts the new vibration function "FC separation system". Developed in a variety of research and development of the flagship model CSR, this is a dampening approach that is ideal for audio in two types of cast iron parts. ■ The leg part CSR is the first time in TAOC middle-class audio rack. Performance beyond its class. When both the spikes and spikes are made of cast iron, the combination of vibration dampening properties of cast iron combined with vibration insulation from the spike ground will dramatically increase the resolution and high range of S/N from low to medium to low range.
