kmd500rt-01

01

Super Sound Energy

The purpose of Steel Enclosure exposed for the first time at Seoul Hi-Fi Audio Show in 1999 is to realize zero loss sound energy during transform the electric signal to the audio signal for the audiophile.

KMD is faithful to make Zero Sound Energy Loss when the electric signal is converted into the audio signal.

02

Super Sound Orchestral Arrangement

A large number of recording microphone arrangements at the recording sites covert the audio signal of a sound source of various genres into the electric signal.

KMD desires to express the site where the sound source is occurred by Orchestral Arrangement Technology of Speakers of each frequency range used to convert the electrical signalized sound source into the audio signal. (KMD's Patent)

Super Sound Fidelity

KMD 500RT was specially designed aimed for multi channel audio playback.

KMD speakers of each range (low, middle & high) used to play the sound source as the audio signal are arranged in the way of not toll-boy but individual arranged enclosers to express the place where the three- dimensional sound source has occurred.

Super Universal Sound Origin and Angle

The directional angle of the sound source at the place where the sound source is occurred, can be adjusted.

KMD has a technology in Universal Revolving making 180 degrees on the front side of speakers in case of playing the sound source. It can make the playback controlled in the way of directional angle. (KMD's Patent)

Super Mechanical Based Encloser Structure

Designing of Speaker Enclosure

KMD Designs the Enclosure by using the 3-dimensional CAD Modeling Technology, assemblies and simulates virtually in 3-dimensional CAD system, assembles parts accurately produced by CNC Machining Center, CNC Turning Machine, CAM, and other Computer-Aided Manufacturing software.


KMD offers the high-quality original sound without audio energy loss as it is through 180 degrees Free Revolving Directional Enclosure, Cross- Over Circuits developed by KMD and Drivers by SEAS in Norway
