FD51-4PE (Patreon Edition)

Current Status: Complete!

Motor: Sparkler (Legacy)

In pushing my own abilities and obtaining new data of different approaches to loudspeaker design, FD51-4PE scrapped everything from 4OS and 4PM, and started from scratch. What resulted is many firsts for the driver line up and ideas which would later be picked back up. These include a screw in motor design and a custom hexagon cone profile aiding a smoother response from a full range driver.
