FD52-4OS (Legacy)

This is now a legacy design and it is strongly advised you look at the Elemental or Fidelity series

FD52-4OS is a revision from last years FD51-4OS. It is a full range driver, still based on the 15mm 'Sparkler' magnet motor. Unlike the original FD51 series, the entire FD52 series have the exact same assembly guide which is attached here as well as a detailed breakdown on how to make FD52.

FD52 takes new developments in the project that happened after FD51 and introduces it and also attempts to improve across the board as well. The design is changed from PLA for the chassis, back cap and cone to PETG to help aid in power handling.

FD52 not only supports the same motor but also complies to the dimensions of FD51 so all previous cabinets are compatible including a new one, Valiant 5 which incorporates the first passive radiator to be released as well, PR61

V1.1 Assembly Guide is now up along with a ‘spacer’ stl. This is the replace the 3 back washers in the magnet motor if required. Performance effects are very minimal
