This audio system is a model specially developed by our company for KTV venues. Equipped with an aerospace magnet bass unit and imported Celestion treble unit, it balances low-frequency power and high-frequency clarity, with a wide frequency response (50Hz–18kHz), making it suitable for various musical scenarios.
The high-frequency sound spreads evenly without howling, reducing interference with human voices and ensuring high clarity. The low-frequency sound is flexible, soft yet powerful, while the high-frequency sound is delicate and clear, with ample dynamics and a refined timbre that reveals musical details, offers precise control, and creates a unique dynamic vibe. One set is suitable for spaces of approximately 30 square meters.
