Product Code: VB1X-1G Price: Check Latest VB-1X Cascade VB-1X is an air-curing, liquid damping compound.  Its combination of silca-mica, ceramics and an advanced chemical binder greatly reduces structural resonance by converting vibration into "viscous" friction or low level heat.  It is purple in color when applied and changes to matte black when dry.  VB-1X can be applied with Cascade's SG-1 spray gun.  It can also be applied with a paint brush or roller.  VB-1x works fantastic when applied to the interior of speaker and subwoofer enclosures.  While still wet, clean up is easy with soap and water. VB-1X is especially great for those "economical" pre-made sub enclosures.  Enclosure vibration reduces SPL and negatively effects frequency response.  Applying VB-1X to the inside of your woofer enclosure will seal it, reduce or eliminate cabinet vibration and increase SPL!
