- Key Specs
- RMS Power: 400 watts (The maximum amount of continuous power the device is able to handle.)
- Peak Power Handling: 400 watts (The maximum amount of power an electronic device, like a speaker, can handle without damage. This refers to short bursts of power, while root mean square (RMS) power handling indicates the amount of continuous power a device can sustain. Higher levels of distortion can also occur at peak power levels when the device is powered beyond its recommended usage.)
- Minimum Frequency Response: 5 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Maximum Frequency Response: 2400 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
