Dolby Pro Logic Surround sound
The use of a centre speaker is a key factor in obtaining
a full surround effect when playing sources encoded
with the Dolby Pro Logic Surround sound system.
Centre speakers in a movie theatre make central
sounds, such as dialogue, clearer and create a unified
sound image.
Normally, you have to install a centre speaker
separately, but this speaker system makes it easy to set
up a high-performance home theatre system by
incorporating a high-quality centre speaker system into
the front speakers.

How the centre speaker works
The front left and right speakers are equipped with centre
channel tweeters (see above) angled inwards at 30° to
reproduce high-frequency centre channel sounds. Low-
frequency centre channel sounds are mixed with the front
channel signals and reproduced through the front left and
right full range units. This design produces a high-quality
centralized sound image for the centre channel which
exactly matches the quality of the front channel sound to
provide superior sound quality and a unified sound image
without a cumbersome external centre speaker.
Dynamic Bass Roar (DBR) super woofer
system provides theatre-like bass sound
To provide a theatre-like experience complete with
dynamic bass sounds, this speaker system incorporates
the Super Acoustically-loaded Woofer (SAW) design
(see below) in the right front speaker to form a DBR
super woofer system.
What is the SAW design?
The SAW design features a centrally-positioned woofer
drive unit, two chamber construction, and a long duct.
Through precision control of the acoustics of the two
chambers, the unit can reproduce powerful ultra low
frequencies without muddiness.
Right speaker
In addition, we also included two super woofer modes
designed to bring the dynamic bass sounds found in
movie theatres (mode 1) and concert halls (mode 2) to
your living room.

Power turns on and off automatically
The speakers will turn on automatically when a sound
signal is input and turn off when you've finished
watching a program and the sound signal goes out. So
you don't have to bother using the power switch every
time you use the system.
