JBL LSR6328P

The LSR6328P is the choice for stereo and multi-channel music and post audio applications where accuracy and high SPL are required. With ruler-flat +1 dB/-1.5 dB response from 50 Hz to 20 kHz, low frequency extension to 36 Hz, boundary compensation and JBL's new RMC™ system, the LSR6328P gives you exceptional low frequency performance in any room. The system is bi-amped with a 250 Watt LF amplifier and a 120 Watt HF amplifier. Wall mounting provisions make the LSR6328P perfect for installation in multi-channel editorial rooms.

• Advanced Linear Spatial Reference design ensures flatter-off-axis response for greater clarity at the mix position
• RMC™ Room Mode Correction provides electronic control of room modes. User measurement and calibration kit available.
• Differential Drive® technology with dynamic braking for extended low frequency response and minimal power compression.
