Active High Power 18" Subwoofer
RCF - SUB 8004-AS
'one of the most powerful 18” subwoofers in pro-sound'The SUB 8004-AS is one of the most powerful 18” subwoofers in pro-sound category. Featuring a high power, hypervented 18” woofer, with 4” inside/outside voice coils, this cabinet is designed to deliver a serious amount of low frequency. Powered by a 1250W 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, time delay.
Powerful class D amplifiersRCF's Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. RCF amplifiers deliver an ultra-fast 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.
