Due to extensive research and development, we now lift our classic RPM design to an even higher level. The RPM 9 Carbon uses a new extra heavy chassis which features a special CNC machined MDF plate that incorporates hard resin coated steel pellets to form an extra heavy precise sandwich construction. A special complex heat treatment and a carbon surface coating ensures superior low resonance levels. The mass-loaded chassis is effectively decoupled from its surface using magnetic feet.
