华尔代尔水晶4.C，3年保修

Crystal 4 series has been engineered for excitement — particularly for movies and music, a Crystal 4 system demonstrates coverage and depth usually associated with much more expensive home cinema systems. Intoxicating high frequencies, powerful bass — it’s mostly thanks to our tried and tested driver technology.TheCrystal 4.C centre channel loudspeaker. Possibly the most important speaker in a home cinema system, responsible for approximately 80% of the dialogue, special attention has been paid for an immediate, ‘in the room’ sound with a natural balance. The soft dome tweeter, as seen in all Crystal 4 models ensures a wide dispersion, allowing multiple listeners to experience the same, rich sound-field.
