SUB 718-AS Active Subwoofer
The SUB 718-AS is a compact and powerful subwoofer that delivers uncompromising performance for its class.

Thanks to the powerful 18" woofer, 4" voice coil and 700W Digipro amplifier, the RCF SUB 718-AS is the perfect tool to increase the low end performance of a portable PA system both in terms of output and frequency extension.
The RCF SUB 718-AS integrates a completely new high power 700 Watt digital amplifier coupled with a high performance electronic processor section. These components ensure exceptional output and low distortion via the precision 18" neodymium woofer. The result is a compact, light weight and high powered subwoofer unlike anything else in its class in terms of power, efficiency and low distortion.
The system re-defines subwoofer performance standards in more ways than one. The next generation 700 Watt Digital Amplifier produces an incredibly natural sound, very high output and extremely low distortion. The amplifier also features an innovative solid mechanical aluminum casing which not only stabilizes the amplifier during transportation but also assists in the heat dissipation.
