The Neon 4 is for the lover of smooth, creamy sounds. Which it achieves without sacrificing resolution. The Neon 4’s highlight lies in its lush, upper mids and trebles. As well as a stellar sense of space and positioning from its ATOM XS module. Place these characteristics on a snappy, speedy bass foundation for an immersive, detail-oriented listen.
The Neon 4 features a machined aluminum shell, a sapphire glass faceplate, equipped with 3 balanced armature drivers, a 10mm dynamic driver for lows, fed into FiR Audio’s Kinetic Bass port.
Along with the rest of the Frontier Series, the Neon 4 comes in Universal-Fit and Custom-Fit models.
1x 10mm Kinetic Bass Dynamic Driver
1x OpenDriver Balanced Armature Driver for bass
1x OpenDriver Balanced Armature Driver for mids
1x OpenDriver Balanced Armature Driver for highs (with Sound Reflector)
