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
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.
55 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).
73 - 20000 Hz
Maximum Sound Pressure Level (SPL)
This is the maximum Sound Pressure Level (SPL) of the studio monitor. The higher the SPL rating, the louder the monitors are able to go.
123 dB
Digital Inputs
These are the types of digital inputs and interfaces that the studio monitor is able to accept.
Digital S/PDIF
XLR Digital AES/EBU

Holy cow. Amazing buy. Built-in 24/192 DAC alone is worth it

August 16, 2012

I figured I would try my luck on these. I read a couple of reviews on them. They are made by Auzentech, a Korean brand that makes really high end sound cards for computers. I've shopped with Sonic before so I knew I would be OK if I needed to return them if I didnt like them, but I love them. The review I read is at http://www.soundonsound.com/sos/mar10/articles/infrasonicblow4d.htm I also read one here and translated it with Google: http://www.maclife.de/beat/hardware/studio-monitore/test-infrasonic-blow-4d The things I love about these speakers: - Features, features. These babies have a ridiculous amount of options for connections. - High-end 24bit/192kHz DAC My only complaint is no volume control on speaker, but I got over that since I paid
