FD51-4PM (Polymaker Edition)

Current Status: Complete!

Motor: Sparkler (Legacy)

Coming in just after FD51-4OS, FD51-4PM utilises a evolution on the motor used in 4OS and also uses Polymakers light weight material, Polywood. This combination results in a sensitivity matching 2 FD51-4OS drivers at the same power. Add to this a softer suspension and it also allows it to reproduce slightly lower bass response as well.
