Trust JBL Cinema Series speakers and subs to provide peak performance throughout the life of your investment: Systems are designed for superior overall efficiency; transducer-protection circuitry ensures long-term stability.

The Cinema Series is designed for streamlined system setup and operation in a range of configurations. 4281F subwoofers operate in 4-ohm mode, enabling them to be driven with Crown XLC Series amps. The 4281F's 4-pin connectors allow driving the two transducers separately (discrete mode) or together (parallel mode). Hardware is engineered for maximum versatility, with enclosure-top input terminals and binding-post connectors.

Accurate diagnostics help keep your system running at peak performance. Crown XLC amplifiers (available separately) monitor the status of amplification and speaker loads through third-party control and TMS systems when used with the JBL CPi2000 processor (also available separately). Front-panel indicators monitor key statistics such as signal, clip, bridged operation, power standby and fault.

Complete your JBL cinema sound system with the JBL CPi2000 cinema processor, which provides audio enhancement including DSP, room EQ tuning, volume control, and system-fault detection. The JBL CPi2000 processor includes Cinema Series speaker presets for better sound and performance and easier deployment, and can send amplifier and speaker status to a central TMS (Theater Management System) control system.

Q: 7. What's the difference between this DRM 18S cab and the SRM 1850 cab? Why is there no specific sub for the SRM215-V-Flex cabs? I want to get the latter but your Mackie sub lines are confusing.

A: There are several differences between the two models and the best option would be based on your system and the type of application you would be using the subwoofer for. The DRM18S-P is a passive subwoofer capable of handling 500W RMS and 2000W peak power from a separate power amp. The SRM1850 is an active subwoofer which has a built-in power amp capable of producing 800W RMS and 1600W peak. The frequency response range and threshold for SPL are the same for both models. The DRM18S-P can be mounted on a pole or suspended while the SRM1850 is designed to be placed on the floor or stage and should not be pole mounted or suspended. I hope this information is helpful.
