RCF HDL 12-AS Active Subwoofer
The HDL 12-AS is the active subwoofer built to anchor RCF's HDL line array modules, housing a single 12-inch woofer on a 3.0-inch voice coil in a compact enclosure with an integrated digital amplifier. It delivers 1400W peak (700W RMS) and 131 dB SPL, covering 40 to 120 Hz as the low-end foundation under an HDL 6-A or HDL 10-A array.
A built-in stereo crossover with adjustable frequencies routes the array's low end into the sub, and array mechanics on top let the HDL modules stack and fly directly from the enclosure. A heavy-duty grille protects the driver on the road, and Powercon in/out plus XLR audio connectors keep the rig wiring simple.
