Background
Today’s multichannel music and film soundtracks demand more performance
from a centre channel than ever before. High performance centre-channel
loudspeakers must have frequency, phase and sonic characteristics that
closely match your main speakers. When matched correctly, the resulting
surround sound or enhanced stereo presentation will be natural. New higher
resolution multichannel formats mean that correct choice of a centre speaker is
even more critical. By designing our systems with mus ic reproduction foremost
in our minds, Meridian has once again anticipated your needs with the
DSP5500HC, matching the performance of its vertical counterparts.
Meridian DSP5500HC
The DSP5500HC is constructed with steel panels sandwiched between the
rigid inner cabinet and the veneered outer panels on four sides. The two
200mm bass drivers are housed in separate internal enclosures. A third
internal enclosure houses the tweeter and midrange. As a result the acoustic
cabinet is extremely rigid, giving the benefits of extension, clarity and dynamic
range unheard of in conventional centre channels.
Meridian also included innovative DSP technology to compensate for boundary
and corner use. This is a centre speaker that can be installed in almost any
environment with confidence.
The DSP5500HC has been designed to work coherently with the Meridian
DSP5500, DSP6000 and DSP8000 loudspeakers.
