General Features

Monitor Type
Studio monitors can be passive or active. Passive monitors require an outside amplification of the audio signal. Active monitors have a built-in amplifier to provide proper output to the speakers.
Near-Field Active
Peak Power
This is the maximum power rating of the studio monitors. For passive monitors, this is the maximum amount of wattage that the drivers are rated at. For active monitors, this is the maximum amount of wattage that the built-in amplifier sends to each driver.
75 watts
Continuous Power
This is the continuous power rating of the studio monitors. For passive monitors, this is the amount of wattage that the monitor needs to function properly. For active monitors, this is the amount of wattage that the built-in amplifier sends to each driver.
30 watts
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
56 - 20,000 Hz
Crossover Frequency
This is the frequency that the studio monitor is able to separate the audio frequencies that are being sent to the LF driver and the HF driver.
2800 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
100 dB
