The three new self-powered subwoofers from Renkus-Heinz comprise the DR18-1’s PM-1L PowerNet Module produces 128.5dB peak SPL from an 18-inch cone transducer in a vented direct-radiating enclosure: Frequency response is 32 to 120 Hz. The DR18-2’s PM-2L PowerNet Module delivers peaks of 135 dB SPL and frequency response of 32 to 120 Hz from a vented direct-radiating enclosure with dual 18-inch cone transducers. The BPS15-2 uses a high-efficiency seventh-order bandpass enclosure design to produce 135 dB peak SPL and a frequency response of 35 to 250 Hz from dual 15-inch cone transducers driven by the PM-2L PowerNet Module.
The 2,400-watt PM-2L and 1,200W PM-1L PowerNet Modules combine Class-D digital amplification and comprehensive loudspeaker management into a single unit. Loudspeaker-specific processing senses when output current or voltage are about to damage the system and limits them to safe levels.
PowerNet Modules have a high CMRR analog input as standard equipment; they are also available with a CobraNet digital input module that selects from 64 channels of digital audio delivered from Cat-5 copper or UTP optical fiber and delivers up to six separate analog outputs.
Another option, R-Control remote control and supervision, allows gain control and monitoring of amplifier and loudspeaker performance from a central computer.
All three subwoofers are also available in externally powered configurations (DRS18-1B, DRS18-2B and BPS15-2K).
