Key Features
Professional studio monitors for both stereo and surround (e.g., Dolby Atmos) applications
Single-point-source coaxial design for better phase alignment, superior imaging, and symmetrical dispersion
Superior high-frequency reproduction: 1.25-inch (31.75 mm), ultra-low-mass, silk-dome, high-frequency transducer for crystal-clear, natural high end
8-inch, woven-composite, low-frequency driver and front-firing acoustic port produce a powerful, accurate, and smooth bass response with extended low end
Loud and clear: 140W, Class AB biamplification delivers up to 106 dB SPL (Peak, @ 1 meter) without sacrificing tonal balance or audio clarity
35 Hz to 20 kHz frequency response
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
All the connections you need: Balanced XLR, balanced ¼-inch TRS, and unbalanced RCA inputs.
Protection features: RF interference, output-current limiting, over-temperature, transient, subsonic protection and amplifier “soft start” feature (eliminates popping on power-up), plus Power Saver mode (engages after 40 minutes)
Wall and ceiling mountable

Pros & Cons
👍 Pros
- Coaxial design offers a single-point source for superior imaging, phase alignment, and symmetrical sound dispersion.
- Wall and ceiling mountable design provides versatile placement options for optimized studio configurations.
- Dedicated Acoustic Tuning controls allow for precise room compensation, including HF, Midrange, highpass filter, and Acoustic Space.
- Wide frequency response from 35 Hz to 20 kHz ensures detailed audio reproduction across the entire spectrum.
- Robust protection features, including RF interference, over-temperature, and amplifier "soft start," enhance reliability.
👎 Cons
- The 140W Class AB biamplification, while robust, might be a limiting factor for very large control rooms or exceptionally high SPL requirements.
- Achieving optimal acoustic tuning with the available controls may require careful measurement and adjustment in specific room environments.
- While offering balanced and unbalanced inputs, the monitor does not specify any digital input options for direct digital audio connections.
- The Power Saver mode, engaging after 40 minutes of inactivity, could be inconvenient for workflows that require the monitors to be instantly ready.
- An 8-inch low-frequency driver, while capable, might still require a dedicated subwoofer for the deepest sub-bass frequencies in critical listening setups.
