The black SUB 8004-AS Professional Series Active Subwoofer from RCF features a high-power, hypervented 18" woofer with 4" inside/outside voice coils designed to deliver a serious amount of low frequency. Powered by a 2500W digital amplifier module, the SUB 8004-AS can perform in the most demanding situations. The input board includes volume control, deep/punch switch, high-pass switch, phase switch, cardioid, and time delay.

The sub is stackable and lightweight for easy set up and tear down, thanks to the ergonomic handles. A pole receptacle on top and side allows the use of the sub in various configurations. The powder coated front grille integrates a special transparent-to-sound foam backing on the inside to further protect the transducer from dust.

Powerful Class-D Amplifier

RCF's Class-D power amplifier technology packs huge performance, operating with high efficiency into a lightweight solution. RCF amplifiers deliver an ultrafast attack, realistic transient response, and impressive audio performance. The amplifier features a solid machined aluminium structure, which not only stabilises the amplifier during transportation but also helps the fan-less heat dissipation. All the amplifiers present SMPS power supply section to produce maximum output and minimum weight.

The Transducers Innovators

RCF developed advanced transducer technology including the application of high-tech materials such as neodymium, carbon fiber, pure titanium, kevlar, kapton, and mylar hybrids. RCF has been instrumental in technological inventions such as carbon fiber cone molding, double silicon spiders, inside/outside voice coil windings to edge wound voice coil manufacturing and pure titanium diaphragm forming.

Legendary Subwoofers

RCF subwoofers are the first choice of many sound engineers, thanks to the very high SPL levels at very low frequencies, small dimensions compared to the competitors, self-powered design, internal delay control, cardioid configuration options and impressive size/weight to SPL output ratio.

Cabinet & Mechanics

The RCF cabinets are made of baltic birch plywood coated with a textured black finish. The subs are stackable and lightweight, for easy set up and tear down, thanks to the ergonomic handles. A pole receptacle on top and side allows the use of the box in various configurations. The powder coated front grille integrates a special transparent-to-sound foam backing on the inside to further protect the transducers from dust.
