An Impressive Offering From Infrasonic

The Infrasonic BLOW4Ds are a pair of 55-Watt, 4" bi-amplified near-field studio monitor speakers. The BLOW4Ds feature a two-way design to produce high quality sound. Frequency response is expanded downward by a bass reflex system, and expanded upward by a silk dome tweeter for delicate signal reproduction. Their enclosure design also contributes to the broad frequency response.

The BLOW4Ds come equipped with a DA.912 digital interface module, allowing users to utilize a number of digital inputs such as AEU/EBU(XLR), S/PDIF(RCA) and an RCA thru connector. The DAC (Digital-to-Analog Converter) in DA.912 has an astonishing 24-bit/192kHz sample format with 123dB of dynamic range. From the commercial to the home studio, the Infrasonic BLOW4Ds are some of the most outstanding near field studio monitors on the market today. With monitors this accurate and powerful, you'll surely hear what you've been missing.

Excellent!

For the price of these monitors, you get a hell of a bang for your buck.

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

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

Fantastic!

I waited a month to post a review. After 30 days of use, I have had no issues at all. The sound quality is impressive for such a value. Over all, I am impressed and pleased. Shipping time was fast. Everything went off without a hitch. Thanx Sonic!
