CS Series
//
Passive Cardioid Subwoofers
The CS Series combines high-output performance with Fulcrum’s Passive Cardioid Technology™ to reduce rear LF energy, without requiring additional drivers, amplifiers, or DSP. TQ™ Processing optimizes phase response and voicing, allowing the CS Series to deliver focused clarity and control from a compact footprint, making it ideal for challenging acoustic environments.
