RCF Presents New Active TT25/TT22 PA Speakers

The development team at RCF (Radio Cine Forniture) certainly hasn't been resting on its laurels. Since 1949, the Italian manufacturer has been treating us to high-grade audio systems, and from the looks of their new TT22-A II and TT25-A II speakers and TT25-CXA stage monitor, they're not about to quit any time soon.
