General

The RCF SUB 8008-AS Cardioid Groundstack consists of three dual 18-inch active SUB 8008-AS subwoofers that you can stack on top of each other for a cardioid configuration. This way, you focus your bass exactly where you want it and reduce it where you want it. For example, you can keep the bass noise away from your stage, your turntables, your neighbours, you name it. The RCF SUB 8008-AS is a rock-solid, tour-ready subwoofer with plenty of power; a total of up to 4400 Watts per subwoofer! With two 18-inch woofers, you create very powerful bass suitable for medium to large venues, for amplifying live bands, DJs and for playing electronic music in clubs. Thanks to the intelligent DSP with many settings and FiRPHASE filters, your audience will enjoy a transparent, clear sound.

Geweldige subwoofer, veel power. En een super geluid. speelt de 30hz ook nog steeds vloeiend en zonder distorsion. kan niet anders zeggen dan er zeer tevreden mee te zijn.
