STP CRYSTAL two hexagonal acoustic panels for door, dimensions: 19cm x 22cm

Elastic hexagonal-shaped material with triple layer based on polyurethane foam saturated with bitumen with a pressed aluminum sheet. The CRYSTAL acoustic panel effectively disperses and absorbs the return wave produced by a speaker in the opposite direction as well as the metallic resonances of the car door.

STP CRYSTAL Features

• absorbs wave distortion
• guarantees high quality sound
• absorbs speaker waves and metallic resonances of car doors
• easy to apply (self-adhesive)

STP CRYSTAL - Elastic hexagonal-shaped material with triple layer based on polyurethane foam saturated with bitumen with a pressed aluminum sheet.
The CRYSTAL acoustic panel effectively disperses and absorbs the return wave produced by a speaker in the opposite direction as well as the metallic resonances of the car door.


The effectiveness of the CRYSTAL panel is defined by the following three acoustic effects:
1) Absorption of vibrations of the acoustic volume of a car door i.e. elimination of resonances.

2) The absorption of sound in the acoustic volume of a door provides a softening of the sound field in terms of frequency depending on the sound absorption index from the frequency.

3) The fact of finding an average of the sound pressure in the acoustic volume of the
door provides the elimination of acoustic resonances - interference of sound waves. The effect is achieved thanks to the special embossing of the material.
