Home Cinema has become so popular nowadays that an enormous variety of brands and models are
available in various product categories. However, in order to experience a spectacular and real
sensation in surround sound, there is a need for multiple loudspeakers that need to be located and
set-up carefully. The position of the TV monitor must also match the listening area, so as a result the
optimal listening position is limited to a very restricted area. The strict setup requirements, the
number of loudspeakers, and their size, the many wires, the complicated set-up and required
adjustment means many users are not satisfied with their current Home Cinema system.
To counter these limitations, and with 60 years of experience in the world of electronics as an expert in the
physics of audio and video, Kenwood has developed the new DVD entertainment system, AX-7. Using the third
generation of Kenwood's original development “Virtual Front Surround” (VFSIII) and the power of the digital
signal processor from Analog Devices Incorporated (ADI), Kenwood has constructed a unique algorithm for its
new front surround system. The AX-7 is able to recreate the atmosphere of surround sound for Home Cinema
with only 2 loudspeaker enclosures that incorporate a double speaker system (a 2-way 2 speaker hi-fi system
and a single full range effect speaker).
Virtual Front Surround III makes it possible to experience a flexible and spectacular surround sound without the
complicated critical set up of many speakers and without speaker cables cluttering your room
The Virtual Front Surround system enables an expanded acoustic field and offers a spectacular surround
sound with only 2 front speakers.
