C4 4 inch monitor speakers get a lot of specific products and high-end recording studio HIFI audio industry. Using the bass and treble drive unit designed specifically optimized polypropylene material with special treatment of yellow fiberglass cone diaphragm diaphragm and low damping rubber surround material can produce more precise smooth frequency response. Low reflection high hardness die-cast magnesium frames, you can maximize mechanical precision while minimizing speaker output staining possible. 1 "tweeter using a soft ball fiber membrane roof, both light has a certain rigidity, high-precision sound reproduction. Tweeter also has a powerful magnetic circuit, fast response, in order to obtain a more thorough, natural instantaneous response. Voice frequency Self-designed electronic crossover through the completion of the separation before the amplifier input, with a steep decline curve 30db/oct in woofer and tweeter are true. Such a steep decline curve crossover frequency bands modulation down to the lowest point in the frequency range of demanding performance lets divide more thorough clean, while the line-level electronic design divider, completely eliminating the lost sound, distortion, and sometimes severe self-modulation function, to provide users with a very clear and thorough and very smooth over 40KHz frequency response, and to reproduce high-fidelity restore sound effects. Additionally, the configuration of the XLR balanced XLR input jack, 1/4 inch TRS 6.35 TRS input jack, Lotus unbalanced RCA input jack. level master knob and dedicated to different occasions according to low, medium, high frequency corresponding processing "HF ADJUST" knob. box with MDF material from repression, to maximize reduce resonance effects, it has high efficiency, wide dynamic, low distortion, bit reduction does not leak music, gorgeous sense of sweet and modest charm and exciting, it is a professional listener-class standards, pan positioning accuracy, bass Chunhou lively and flexible, low-frequency deep dive capability, a high level of musical expression is impressive, sound and relaxed, dynamic sense and balance is excellent. pursuit of high-quality sound, the sound quality demanding The Hi-Fi enthusiasts dream boutique! appearance with piano perfect combination!
