The RPD is an offshoot of the original RMD design.  It uses a Seas Excel paper midrange driver, paired with a paper cone Peerless XXLS woofer. All available configurations are possible, including active bass and DEQX digital crossover. 

The RPD offers slightly higher sensitivity and a slightly warmer sound than the RMD.  The RMD can be taken as the ultimate in resolution and sensation.  The paper version can be taken as the ultimate compromise that the music loving audiophile seeks, striking the balance between detail and listen-ability.
