RCF SUB 9019-AS Active 4000 W 19-Inch High-Powered Subwoofer - Black

The RCF SUB 9019-AS (SUB9019-AS, SUB 9019AS) is a single 19-inch active touring subwoofer for live sound, DJ and rental systems that need deep, controlled bass from one cabinet. A 4000 W peak Class-D amplifier drives a 19-inch neodymium woofer with a 4-inch voice coil for up to 138 dB max SPL and a 30 Hz to 200 Hz frequency response, in a weatherproof plywood cabinet that weighs 117.73 lb (53.4 kg).

It is set up two ways. RDNet networked control gives full remote access to EQ, delay, cardioid and Bass Motion Control (BMC) settings over etherCON. RDTap lets you tap a smartphone running the RDTap app on the rear-panel RDTap logo to load or read a configuration, even when the subwoofer is unpowered, so a whole system can be set before it is rigged. Factory ACE (Advanced Crossover Engine) presets match time delay and phase with RCF FiRPHASE full-range speakers.

SUB 9019-AS specifications

Can I set it up without powering it on?

Yes. With the RDTap app, you tap your phone on the RDTap logo on the back panel to transfer presets, EQ, delay and time alignment, or to read the subwoofer's current status, while it is unpowered. The transfer only works at close range, so changes go only to the unit you tap.

Which RCF speakers does it pair with?

RCF FiRPHASE full-range speakers with a factory ACE preset. Connect the speaker to the subwoofer, then select its preset in RDNet or RDTap. RCF names the HDL 20-A and HDL 6-A as upgrade pairings, and shows four HDL 28-A modules over three SUB 9019-AS in a cardioid setup.

How do I move it?

Add the CRT60657 front cart, a detachable wheel board with four 100 mm (3.94 in) wheels that attaches to the cart connections on the cabinet. The cart is sold separately. The cabinet also has one handle on each side.

Can it be flown?

Yes, with RCF's modular Subwoofer Suspension Kit, which uses high-strength steel parts and also supports cardioid configurations. The FLB60676 universal subwoofer flybar is part of that system; RCF's Subwoofer Suspension Kit guide lists the exact parts and limits for each configuration.

SUB 9019-AS, SUB 9029-AS or SUB 8006-AS?

The SUB 9019-AS is the single 19-inch model: 4000 W peak, 138 dB, 30 Hz to 200 Hz, 29.72 in wide and 117.73 lb. The SUB 9029-AS doubles it to two 19-inch woofers with 8000 W peak, 142 dB and 25 Hz to 200 Hz, in a 51.57 in wide cabinet that weighs 205.03 lb. The SUB 8006-AS uses two 18-inch woofers with 5000 W peak, 141 dB and 30 Hz to 120 Hz, and weighs 212.53 lb. Pick the SUB 9019-AS for the lightest and most compact of the three.

What are the transducer and cabinet built from?

The woofer uses lightweight aluminum core coils, a high-damping cellulose cone, composite spiders and a 4-layer inside-outside voice coil, with a neodymium magnet RCF rates 20% stronger than typical neodymium grades. The cabinet is weatherproof plywood with a polyurea finish, and the magnetic rain cover protects the connection panel from rain and dust.
