"A supreme acoustic experience that combines the rigidity of metal and the tone of plywood."

[Brass copper plywood coating inner baffle + PCD-1]
Cutting edge audio upgrade that combines sound quality and durability.

Brass copper plywood coated inner baffle + PCD-1 is an audio part that thoroughly pursues both improved sound quality and durability.
The high density and rigidity of brass-copper plywood minimizes sound distortion and clearly reproduces the sound waves emitted from the speakers. In addition, PCD-1 provides an optimal acoustic space by adding its vibration suppression ability and improved acoustic properties.

PCD-1 effectively suppresses unnecessary resonance in the speaker and vehicle installation, increasing the purity of sound quality and highlighting the original details of music. This maximizes the speaker's performance, delivering deep bass and delicate, sharp treble.
