Key Features
Professional studio monitors for music and other audio production.
Superior high-frequency reproduction: 1-inch (25 mm), ultra-low-mass, silk-dome, high-frequency transducer for crystal-clear, natural high end.
Custom-tuned 120˚(H) x 60˚(V) EBM waveguide provides a wide sweet spot for superior stereo imaging.
4.5-inch, woven-composite, low-frequency drivers produce a powerful, accurate, and smooth bass response with extended low end.
55 Hz to 20 kHz frequency response.
Front-firing acoustic port for superior bass-frequency reproduction and optimized, resonance-suppressing internal bracing.
Loud and clear: 50W, Class AB biamplification delivers up to 99 dB SPL (Peak, @ 1 meter) without sacrificing tonal balance or audio clarity.
All the connections you need: Balanced XLR, balanced ¼-inch TRS, and unbalanced RCA inputs.
Customize for your room with precise Acoustic Tuning controls: HF and Midrange, highpass filter, and Acoustic Space control (flat, -2, -4 dB) to compensate for speaker position near a wall or corner.
Protection features: RF interference, output-current limiting, over-temperature, transient, subsonic protection and amplifier “soft start” feature (eliminates popping on power-up).
