Loudspeaker Specifications

High Frequency Driver Size
This is the size of the high frequency driver. Common sizes include 1", 1-1/2" and 2".
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).
80 - 18000 Hz
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
98 dB
Maximum Sound Pressure Level SPL
This is the maximum Sound Pressure Level (SPL) of the professional loudspeaker. The higher the SPL rating, the louder the monitors are able to go.
128 dB
