Turbosound M-15B – 2200W 15" Active Subwoofer
Overview:
The Turbosound M-15B 2200W 15" Active Subwoofer delivers powerful low-frequency reinforcement for portable PA and installation systems. Its 2,200-watt Class-D amplifier uses Klark Teknik technology for efficient performance. The high-excursion 15" LF driver and 4" voice coil produce tight, articulate bass. Meanwhile, the advanced DSP module provides dynamic equalisation and limiting functions. The bandpass enclosure further enhances bass output while helping minimise distortion.
Key Features:
• Efficient Class-D Amplification: Klark Teknik Class-D technology delivers 2,200 watts while reducing bulky power supplies and heavy heat sinks.
• Advanced DSP Processing: The advanced DSP module provides dynamic equalisation and limiting functions for controlled system performance.
• Powerful 4-Inch Voice Coil: The 4" voice coil supports high power handling while providing effective heat dissipation during demanding operation.
• Optimised Bandpass Enclosure: The bandpass design enhances bass output while minimising distortion and providing steep cut-off slopes.
