Capable of delivering 3600W RMS—and 7200W peak—the RCF SUB 9006-AS is an active subwoofer with two 18" neodymium woofers and 4.0" inside-out voice coils. As such, it can deliver plenty of heft and weight in the low frequencies, making it suitable for live sound applications, from clubs to ballrooms to houses of worship.

The unit puts out sound between 30 and 400 Hz, giving you a DSP-controlled input section. Here you'll find the ability to choose among presets and manipulate delay settings. The subwoofer can handle a maximum SPL of 142 dB, rendering it suitable for reasonably loud environs. XLR connections are provided, and input signals can be either balanced or unbalanced, further expanding the unit's versatility. To interface with RCF's RDnet monitor and control system, the SUB 9006-AS sports Ethercon ports.

Controls are offered for Gain, EQ, Preset, Phase Switch, and Output Delay. The SUB 9006-AS' cabinet is fashioned out of Baltic birch and capped with a steel grille. This unit pairs well with RCF D-Line HDL50-A and HDL-10A array systems.
