Description
The Fostex NF04R Compact 4" 2-Way Active Studio Monitor - 50 W is built for accurate and balanced sound reproduction in near-field environments, whether at home or in the studio. Featuring a 4" HR-shaped woofer and a 0.75" UFLC soft-dome tweeter, each powered by dedicated Class-D amplifiers (30W and 20W), it delivers detailed sound with tight, surprisingly deep bass for its size. Advanced technologies like UDR Tangential Edge and Push-Pull Damper minimize unwanted resonance, ensuring clear mids and lows, while the UFLC tweeter provides faithful high-frequency response with long-term stability.
Designed with flexibility in mind, the NF04R offers adjustable woofer and tweeter levels, a gain switch for input matching, and versatile connectivity through both balanced XLR and unbalanced 1/4" TS inputs. Its lightweight, resin-molded enclosure with internal cushioning ensures durability and stability while preventing rattling. Compact enough for desktop setups yet powerful for critical mixing tasks, the NF04R is an excellent choice for producers and engineers seeking reliable near-field monitoring in smaller spaces.
