The FOSTEX FE-NV2 series continues FOSTEX's tradition of full-range regular units. While maintaining its bright and resonant sound, the series achieves a three-dimensional soundstage representation. It offers a relaxed low-frequency response and a refined, smooth reproduction of mid-to-high frequencies for a fulfilling music experience. Available in sizes ranging from 8cm to 20cm, the NV2 series uses a newly developed cone paper made from ultra-refined kenaf as the primary material. By blending non-wood pulp, chemical fibers, and minerals, it enhances propagation speed and rigidity. Additionally, it eliminates eyelets across all sizes to reduce harmonic distortion in the midrange. With changes in adhesives, the NV2 series further improves environmental compatibility compared to its predecessor.
