Klein & Hummel O300R
Active Triamped Studio Monitor (Right)

O300R

FEATURES:

Sophisticated 3-way system

• The most important frequency spectrum lies in the ideal broadcast zone of the loudspeaker
• Extremely low-distortion reproduction
• Exceptionally neutral sound stage from 40 Hz to 20 kHz
• No standing waves in enclosure
• No partial coloration
• No comb-filter effect

Unconventional enclosure concept

• Very compact enclosure constructed of advanced materials
• Avoidance of resonance via combination of MDF and LRIM (Low Resonance Integral Moulding)
• Very accurate bass reproduction via sealed enclosure
• Precision centers of loudspeaker are on one plane
• Homogenous baffle with no diffraction or fastening elements and with excellent self-damping properties
• Extremely wide effective listening area for main monitor via horizontal installation
• Numerous installation possibilities
• Optional baffle cover/grill
• Magnetically shielded

Functional waveguide

• Dispersion is horizontally wide
• Increased freedom of movement at mixing console
• Vertically narrow sound dispersion reducing early reflections off console surface
• Perfect dispersion pattern

Advanced electronics

• Integrated electronic limiter for each driver
• Active crossover equalizer with 24 dB/oct.
• AF-input equipped with minimal distortion input circuit
• Power and overload/limiter-display integrated into Klein + Hummel logo
• 3 x 4 room-matching circuitry for different placement options
