Active high powered 18" subwoofer

Order Code: SUB8004AS
Our Price: $4,725.00

With more power on board than RCF's already monster 4PRO8003A, the all new single 18" SUB8004AS kicks hard where it feels good.

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.

Mono input only - no crossover output. Run this sub as part of an externally crossed and controlled speaker system.

For even bigger grunt and with massive power, check out the thunderous 2 x 18" version - SUB8006-AS
